Smart Summary: A web material structuring belt consists of two main parts: a support layer and a structuring layer. The structuring layer is placed on top of the support layer and can have strips made from special material. These strips have ends (termini portions) and middle sections (non-termini portions). The middle sections can create a gap seam when placed together. There are also techniques for wrapping the structuring layer around the support layer. 🚀 TL;DR
A web material structuring belt may include a support layer and a structuring layer. The structuring layer may be disposed on the support layer in a facing relationship. The structuring layer may include one or more strips of structuring layer material. The structuring layer may comprise termini portions and non-termini portions. Two or more non-termini portions of the one or more strips of structuring layer material may form a gap seam. Also disclosed are methods for wrapping a structuring layer about a support layer.

This application claims the benefit of U.S. Provisional Application No. 63/708,270, filed October 17, 2024, the substance of which is incorporated herein by reference.
The present disclosure relates generally to molding belts and more specifically to molding belts comprising a structuring layer wrapped around at least a portion of a support layer thereof.
The discussion of shortcomings and needs existing in the field prior to the present disclosure is in no way an admission that such shortcomings and needs were recognized by those skilled in the art prior to the present disclosure.
The tissue industry is a highly competitive, highly technical industry. It includes a number of paper making processes ranging from low bulk conventional wet press processes to high bulk through air dried (TAD) processes. The papermaking transformations that primarily drive product performance include headbox layering, wet transfer from a forming wire to a molding or structuring template, creping the sheet from a Yankee dryer, and embossing.
Papermaking belts are continuous loops typically formed by taking a strip of material (either a support layer and/or a structuring layer), circling it to bring the ends together, and then joining the ends to form a continuous loop. This process creates one significant joint where the two ends of the article meet perpendicular to the machine direction and going from edge to edge in the cross direction. An alternative method for making belt is using strips of material that are narrower than the width of the finished belt and looping or winding them in a continuous fashion to create a full width belt. This requires joining the edges in the machine direction, cross direction, or in any direction in which the strips of material are wound. Winding creates more joints or seams that need to be managed for quality and runnability.
When two different articles/layers/planes meet an unwanted potential exists for discontinuities such as different sizes in gaps between the two materials, different thicknesses, and differences in the filled pattern areas. Different thicknesses may arise, for example, as an additive thickness if the two articles overlap at the junction, or due to differences associated with article variability in abutting, gap, or overlapping junctions. Differences in the filled pattern areas may arise, for example, if the articles do not exactly mirror or register and align. Discontinuities in openings, closings, thickness, strength, air permeability etc. may translate to discontinuities in the papermaking process that may lead to speed, drying, belt hygiene, creping issues as well as imperfections in the finished sheet. For example, the paper machine will need to slow down to mitigate the impact of “speed bumps” as less speed means less force and more ability for the system to flex and to adsorb the discontinuity of, for example, a dry or wet spot caused by the belt discontinuity or to be able to crepe a heavily patterned area. In a worst case, the areas of discontinuity may create sheet breaks that neither speed nor increasing material or strength may overcome and the belt simply cannot be run continuously.
The discontinuities may also lead to poor absorbency, softness, strength, surface volume, pattern visual and thickness for the consumer in the final paper product. Such issues may impact the ability to convert the substrate into a finished saleable form, with wet spots, caliper changes, strength variability leading to substrate web breaks on a converting line. Thus, discontinuities may disproportionately impact the line when running at higher commercial line speeds. All of these issues may impact the compressibility of a wound roll or stacked sheets, which may impede reliably winding or stacking, packaging, or palletizing the finished product form.
A complication exists in that papermaking belts must balance the need for durability with the need for high air permeability to form fibers and dry the sheet. Hence, papermaking belts, including structuring and supporting layers, are typically designed to be as durable as possible while including as little material as possible. One significant failure mode is holes and tears in the belt, which under the high speeds, temperatures, strains, and loads of papermaking may propagate to a point where the belt is not runnable either because it has lost structural integrity, or it is leaving holes, tears or non-patterned areas in the finished product sheet or causing sheet breaks because of the large discontinuity of the tear or hole. Uniform structuring and support layer materials rely solely on the integrity of the material properties to resist and contain a hole or tear.
A need, therefore, exists for paper making belts that are durable, allow for adequate air flow, and that reduce the issues correlated with discontinuities in structuring layers.
Various embodiments solve the above-mentioned problems and provide methods and devices useful for paper making belts that are durable, allow for adequate and potentially improved air flow, and that surprisingly reduce the issues correlated with discontinuities in structuring layers by providing a particular type of discontinuity, a gap seam, between non-termini portions of strips wrapped around a support layer to form a structuring layer.

It should be understood that the various embodiments are not limited to the examples illustrated in the figures.
This disclosure is written to describe the invention to a person having ordinary skill in the art, who will understand that this disclosure is not limited to the specific examples or embodiments described. The examples and embodiments are single instances of the invention which will make a much larger scope apparent to the person having ordinary skill in the art. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by the person having ordinary skill in the art. It is also to be understood that the terminology used herein is for the purpose of describing examples and embodiments only, and is not intended to be limiting, since the scope of the present disclosure will be limited only by the appended claims.
All the features disclosed in this specification (including any accompanying claims, abstract, and drawings) may be replaced by alternative features serving the same, equivalent, or similar purpose, unless expressly stated otherwise. Thus, unless expressly stated otherwise, each feature disclosed is one example only of a generic series of equivalent or similar features. The examples and embodiments described herein are for illustrative purposes only and that various modifications or changes in light thereof will be suggested to the person having ordinary skill in the art and are to be included within the spirit and purview of this application. Many variations and modifications may be made to the embodiments of the disclosure without departing substantially from the spirit and principles of the disclosure. All such modifications and variations are intended to be included herein within the scope of this disclosure. For example, unless otherwise indicated, the present disclosure is not limited to particular materials, manufacturing processes, or the like, as such may vary. It is also to be understood that the terminology used herein is for purposes of describing particular embodiments only and is not intended to be limiting. It is also possible in the present disclosure that steps may be executed in different sequence where this is logically possible.
All numeric values are herein assumed to be modified by the term “about,” whether or not explicitly indicated. The term “about” generally refers to a range of numbers that one of skill in the art would consider equivalent to the recited value (for example, having the same function or result). In many instances, the term “about” may include numbers that are rounded to the nearest significant figure.
In everyday usage, indefinite articles (like “a” or “an”) precede countable nouns and noncountable nouns almost never take indefinite articles. It must be noted, therefore, that, as used in this specification and in the claims that follow, the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a support” includes a plurality of supports. Particularly when a single countable noun is listed as an element in a claim, this specification will generally use a phrase such as “a single.” For example, “a single support.”
Where a range of values is provided, it is understood that each intervening value, to the tenth of the unit of the lower limit (unless the context clearly dictates otherwise), between the upper and lower limit of that range, and any other stated or intervening value in that stated range, is encompassed within the disclosure. The upper and lower limits of these smaller ranges may independently be included in the smaller ranges and are also encompassed within the disclosure, subject to any specifically excluded limit in the stated range. Where the stated range includes one or both of the limits, ranges excluding either or both of those included limits are also included in the disclosure.
In this specification and in the claims that follow, reference will be made to a number of terms that shall be defined to have the following meanings unless a contrary intention is apparent.
“Disposed on” refers to a positional state indicating that one object or material is arranged in a position adjacent to the position of another object or material. The term does not require or exclude the presence of intervening objects, materials, or layers.
“Align” or “aligned” or “aligning” means to place or to arrange in a straight line or along an axis. Aligning edges of substrates or layers, therefore, means arranging the substrates so that the edges in question extend along approximately the same line or along approximately parallel lines. It is to be appreciated that aligning edges of substrates may be accomplished in a variety of ways, including placing the substrates one on top of the other or side by side.
“Facing relationship” refers to a relative positioning of materials, such as substrates, in which a surface of one material is oriented toward a surface of another material. For example, when two layers are stacked on top of each other, they are in a facing relationship. The term does not require or exclude the presence of intervening objects, materials, or layers. Any of the structuring layers described herein may be placed into a facing relationship with other structuring layers and/or with a support layer.
“Machine direction” (MD) refers to the direction of material flow through a process. In addition, relative placement and movement of material may be described as flowing in the machine direction through a process from upstream in the process to downstream in the process.
“Cross direction” (CD) refers to a direction that is generally perpendicular to the machine direction.
“Major axis” of an elongated strip refers to the longest straight line that may be drawn within the strip, extending from one end of the strip to the other, and passing through its center or midpoint. The major axis may define the primary direction of elongation and represents the strip's greatest dimension in terms of length. In many cases, the major axis may be used as a reference for measuring and describing the strip's size and orientation.
“Minor axis” of an elongated strip refers to the shortest straight line that may be drawn within the strip, perpendicular to its major axis, and passing through the strip’s center or midpoint. The minor axis may represents the strip's smallest dimension in terms of width or thickness.
“Termini” refers to the two opposite ends or extremities of a long, narrow object, material, or structure. These are the specific points or sections located at the furthest points from each other along the length of the structure. In other words, it may refer to portions of an elongated strip located at the furthest points from each other along the length of the elongated strip. As an example, a termini portion of a strip may be an end, a side, or an edge of the strip lying at one of two furthest extremities along a major axis of the strip or along an axis that is parallel to the major axis.
“Non-termini” refers to the central or intermediate section of a long, narrow object, material, or structure that is not located at either end or extremity. In other words, it may refer to portions of an elongated strip that lies between the two ends or termini. This portion may vary in length and width, but it is distinct from the ends or termini. As an example, a non-termini portion of a strip may be an end, a side, or an edge of the strip lying at one of two furthest extremities along a minor axis of the strip or along an axis that is parallel to the minor axis.
“Seam” refers to a perceptible or conceptual boundary, interface, or transition zone between two materials, surfaces, or edges, characterized by their close proximity, adjacency, and/or alignment.
“Non-termini seam” in the context of an elongated strip refers to a perceptible or conceptual boundary or interface that exists along the length of the strip but that does not occur at either end of the strip. This seam may exist, for example, between adjacent non-termini portions of one or more strips wound about a support layer. In essence, a non-termini seam is a seam that runs along the body of the elongated strip.
“Termini seam” in the context of an elongated strip refers to a perceptible or conceptual boundary or interface that occurs specifically at one or both ends of the strip. This seam is characterized by its presence at the strip’s endpoints. In other words, a termini seam is a seam that is located at the extremities of the elongated strip, where the strip physically ends or terminates.
“Abutting seam” may refer to a type of termini seam or to a type of non-termini seam. In the context of a termini seam, “abutting seam” refers to a perceptible or conceptual boundary, interface, or transition zone between a first termini portion and a second termini portion, in which the first termini portion contacts but does not overlap or interlock with the second termini portion. In the context of a non-termini seam, “abutting seam” refers to a perceptible or conceptual boundary, interface, or transition zone between a first non-termini portion and a second non-termini portion, in which the first non-termini portion contacts but does not overlap or interlock with the second non-termini portion. In either context, the first non-termini portion and the second non-termini portion may be components of the same or different elongated strip or structuring layer, for example.
“Gap seam” may refer to a type of termini seam or to a type of non-termini seam. In the context of a termini seam, “gap seam” refers to a perceptible or conceptual boundary, interface, or transition zone between a first termini portion and a second termini portion, characterized by a deliberate gap or space therebetween. Unlike an abutting seam, where the ends of the strip come into direct contact, a gap seam leaves a space or opening between the ends of the strip. In the context of a non-termini seam, “gap seam” refers to a perceptible or conceptual boundary, interface, or transition zone between a first non-termini portion and a second non-termini portion, characterized by a deliberate gap or space therebetween. Unlike an abutting seam, where the sides of a strip or a pair of adjacent strips come into direct contact, a gap seam leaves a space or opening between the adjacent non-termini sides. In either context, the first non-termini portion and the second non-termini portion may be components of the same or different elongated strip or structuring layer, for example.
“Overlapping seam” may refer to a type of termini seam or to a type of non-termini seam. In the context of a termini seam, “overlapping seam” refers to a perceptible or conceptual boundary, interface, or transition zone between a first termini portion and a second termini portion, in which the first termini portion extends over the second termini portion to cover it partly or completely. In the context of a non-termini seam, “overlapping seam” refers to a perceptible or conceptual boundary, interface, or transition zone between a first non-termini portion and a second non-termini portion, in which the first termini portion extends over the second termini portion to cover it partly or completely. In either context, the first non-termini portion and the second non-termini portion may be components of the same or different elongated strip or structuring layer, for example.
“x-y interlocking overlap seam” may refer to a type of termini seam or to a type of non-termini seam. In the context of a termini seam, “x-y interlocking overlap seam” refers to a perceptible or conceptual boundary, interface, or transition zone between a first termini portion and a second termini portion, in which the first termini portion interlocks with the second termini portion to resist separation in an x-direction, along the minor axis, and in a y-direction long the major axis. In the context of a non-termini seam, “x-y interlocking overlap seam” refers to a perceptible or conceptual boundary, interface, or transition zone between a first non-termini portion and a second non-termini portion, in which the first non-termini portion interlocks with the second non-termini portion to resist separation in an x-direction, along the minor axis, and in a y-direction long the major axis. In either context, the first non-termini portion and the second non-termini portion may be components of the same or different elongated strip or structuring layer, for example.
“z-interlocking overlap seam” may refer to a type of termini seam or to a type of non-termini seam. In the context of a termini seam, “z-interlocking overlap seam” refers to a perceptible or conceptual boundary, interface, or transition zone between a first termini portion and a second termini portion, in which in which the first termini portion interlocks or at least overlaps with the second termini portion to resist separation in a z-direction that is orthogonal to the major and minor axis. In the context of a non-termini seam, “z-interlocking overlap seam” refers to a perceptible or conceptual boundary, interface, or transition zone between a first non-termini portion and a second non-termini portion, in which the first non-termini portion interlocks or at least overlaps with the second non-termini portion to resist separation in a z-direction that is orthogonal to the major and minor axis.
“Internally wrapped” refers to a method of wrapping or winding a strip of material in such a way that it passes through the central space or core of another object, such as a support layer in the form of a continuous or endless loop. The term may also describe the state of a strip after wrapped about a support layer according to such a method.
“Externally wrapped” refers to a method of wrapping or winding a strip of material in such a way that it does not pass through the central space or core of another object, such as a support layer in the form of a continuous or endless loop. The term may also describe the state of a strip after wrapped about a support layer according to such a method.
“Wrapped in a direction” such as “wrapped in a machine direction MD” or “wrapped in a cross direction CD” refers to the act of winding or encircling an object with a material, such as a strip of fabric, tape, or any flexible material, while following a specific path or orientation. This path or orientation may be linear, curved, diagonal, or any other specified course, depending on the intended purpose or design. The phrase “wrapping in a direction” highlights the deliberate and controlled manner in which an object is enveloped or covered by a material, taking into consideration the desired path or orientation of the wrapping process. The term may also describe the state of a strip after wrapped about a support layer according to such a method.
“Spirally wrapped” refers to a method of wrapping or winding a material, such as a strip of fabric, tape, wire, or any flexible substance, around an object in a spiral or helical fashion. In this wrapping technique, the material is wound around the object’s surface in a continuous, repetitive spiral pattern, creating layers of overlapping or closely spaced turns. “Spirally wrapped” emphasizes the helical or spiral nature of the wrapping pattern, distinguishing it from other wrapping techniques that may involve linear or more complex winding patterns. The term may also describe the state of a strip after wrapped about a support layer according to such a method.
FIG. 1A is a schematic perspective view of a method 10 for wrapping a support layer 200 with a structuring layer 300. The method 10 may comprise disposing the support layer 200 on a plurality of rollers 14 supported by a mandrel stand 12. The rollers 14 that support the support layer 200 may extend from the mandrel stand 12 in a cross direction CD that is substantially orthogonal to a machine direction MD in which the support layer will ultimately be used as a component of a web material structuring belt. A second set of removable mandrel stands 12 could be disposed opposite the first set to eliminate cantilevering of the rollers 14. The second set would be removable to allow belts to be put on and taken off the rollers. The structuring layer 300 may comprise a structuring layer material 301, in the form of a strip 400, which may optionally coiled into a roll 302. The strip 400 may be disposed on the support layer 200 in a facing relationship therewith. The strip 400 may comprise a major axis 440 and may be disposed on the support layer such that the major axis 440 is at a first angle 441 relative to the machine direction MD and at a second angle 442 relative to the cross direction CD.
FIG. 1B is a schematic top view illustration showing a convention for measuring angles between an axis and either the machine direction MD or the cross direction CD. It is to be appreciated that the machine direction MD may extend in two directions as shown. Similarly, it is to be appreciated that the cross direction CD may extend in two direction as shown. The machine direction MD and the cross direction CD may intersect and may be orthogonal relative to each other. To measure the angle at which an axis 440a, 440b is positioned relative to the machine direction MD, start on the line defining the machine direction MD and rotate toward the axis in either a clockwise or a counterclockwise direction about the intersection of the machine direction and the cross direction to reach the axis. Counterclockwise rotation results in a negative angle. Clockwise rotation results in a positive angle. It is to be appreciated that the axis 440a, 440b may be at any angle relative to the cross direction CD, but that once the angle reaches 90 degrees or -90 degrees, it is more practical to measure the angle relative to the machine direction MD. Similarly, the axis 440a, 440b may be at any angle relative to the machine direction MD, but that once the angle reaches 90 degrees or -90 degrees, it is more practical to measure the angle relative to the cross direction CD. Thus, practically speaking the angle may always be expressed in a range of from 0 to 90 degrees or from 0 to -90 degrees. For example, angle 441a may be from 0 (440a is aligned with the machine direction MD) to -90 (440a is aligned with the cross direction CD). Similarly, angle 441b can be from 0 (440b is aligned with the machine direction MD) to 90 (440b is aligned with the cross direction CD). Likewise, angle 442a can be from 0 (440a is aligned with the cross direction CD) to 90 (440a is aligned with the machine direction MD). Finally, angle 441b can be from 0 (440b is aligned with the cross direction CD) to -90 (440b is aligned with the machine direction MD).
Referring again to FIG. 1, it is to be appreciated that the first angle 441 relative to the machine direction MD may be from about -90 degrees to about 90 degrees, or from greater than -90 to less than 90 degrees, or from greater than about -90 to less than about 90 degrees, or from about -85 degrees to about 85 degrees, or from about -80 degrees to about 80 degrees, or from about -75 degrees to about 75 degrees, or from about -70 degrees to about 70 degrees, or from about -65 degrees to about 65 degrees, or from about -60 degrees to about 60 degrees, or from about -55 degrees to about 55 degrees, or from about -50 degrees to about 50 degrees, or from about -45 degrees to about 45 degrees, or from about -40 degrees to about 40 degrees, or from about -35 degrees to about 35 degrees, or from about -30 degrees to about 30 degrees, or from about -25 degrees to about 25 degrees, or from about -20 degrees to about 20 degrees, or from about -15 degrees to about 15 degrees, or from about -10 degrees to about 10 degrees, or from about -5 degrees to about 5 degrees, or about 0 degrees.
It is to be appreciated that since the cross direction CD is perpendicular to the machine direction, the value of the angle 442 between the major axis 440 and the cross direction CD follows mathematically based on specification of the angle 441 or vice versa. The second angle 442 relative to the cross direction CD may be from about -90 degrees to about 90 degrees, or from greater than -90 to less than 90 degrees, or from greater than about -90 to less than about 90 degrees, or from about -85 degrees to about 85 degrees, or from about -80 degrees to about 80 degrees, or from about -75 degrees to about 75 degrees, or from about -70 degrees to about 70 degrees, or from about -65 degrees to about 65 degrees, or from about -60 degrees to about 60 degrees, or from about -55 degrees to about 55 degrees, or from about -50 degrees to about 50 degrees, or from about -45 degrees to about 45 degrees, or from about -40 degrees to about 40 degrees, or from about -35 degrees to about 35 degrees, or from about -30 degrees to about 30 degrees, or from about -25 degrees to about 25 degrees, or from about -20 degrees to about 20 degrees, or from about -15 degrees to about 15 degrees, or from about -10 degrees to about 10 degrees, or from about -5 degrees to about 5 degrees, or about 0 degrees.
For all embodiments described herein, it is to be appreciated that the first angle 441 and the second angle 442 may be the same or different. It is also to be appreciated, for all embodiments described herein that the first angle 441 and/or the second angle 442 may vary for adjacent strips 400 and may even vary for a single strip 400 when the single strip 400 is repeatedly wrapped around the support layer 200 the angle 441 and/or the angle 442 may vary for adjacent portions of the same strip 400.
FIG. 2A, FIG. 2B, and FIG. 2C cooperate to illustrate various strips 400 having non-termini portions 420 and termini portions 430. Each strip 400 may comprise a major axis 440 extending between termini portions 430 of the strip 400. Each strip 400 may also comprise and a minor axis 450 extending between non-termini portions 420 of the strip 400.

It is also to be appreciated that although the sides 421, 422, 423 of the illustrated strips are approximately parallel, this need not be the case. Additionally, any combination of patterns may be employed, for example, on side of a strip 400 may be straight and another side of that same strip 400 may be curved, wavy, or zig-zagged.
According to various embodiments, it is possible to create a structuring layer material 3 mm wide and approximately 23,000 kilometers long. The structuring layer may have straight edges or curved or any variety of shape. The layer may have holes of any geometry. The structuring layer does not need to be continuous – if it is unable to hold itself together in a single layer a topical layer with light temporary adhesive may be used to maintain the integrity of the layer through treatment of bonding with the support layer. Optionally an associating layer may be used to carry the discontinuous structuring pattern, as described in US Pat. Application Serial No. US 2023/0138090 and US Pat. Application Serial No. US 2023/0137439, which are hereby incorporated by reference in their entireties. For example, according to various embodiments, it is possible to place an endless support layer approximately 5.2 meters wide and 21.3meters circumference with optionally applied associating material, bonding layer (as described in in US Pat. Application Serial No. US 2023/0139935, which is incorporated by reference in its entirety) or modifying material (as described in US Pat. Application Serial No. US 2023/0140783, which is incorporated by reference in its entirety) onto two mandrels so that the support layer is lightly tensioned with outward pressure on two opposing ends of the support layer loop and the outer surface of the support layer is free from contact with the mandrels. According to various embodiments, it is possible to initiate an orthogonal or spiral wrap in the machine direction or cross direction by positioning the structuring layer and the support layer in contact with one another. According to various embodiments, it is possible to continue the wind across to cover the support layer so that the structuring layer leaves a 2 mm gap seam between the non-termini edges of each wrap. The termini seams may be abut, gap, or overlap. For example, according to various embodiments, it is possible to treat the layers to bond, as for example in US20230138090. The structuring layer pattern and the non-termini gap seam may become an integrated macro pattern.
According to various embodiments, it is possible to create a structuring layer material with non-thermoplastic, thermoset polymer, UV light curable polymer, silicone rubber and/or non-silicone vulcanized rubber film or apertured film and/or porous film and/or laser-abraded film and/or laser-etched film and/or perforated film narrower than the width of the support layer and where the layer has a curvature such that the second non-termini edge is longer in length than the first non-termini edge. Alternatively, according to various embodiments, it is possible to provide a structuring layer of woven material, wire mesh or extruded plastic netting narrower than the width of the support layer where the layer has a curvature such that the second non-termini edge is longer in length than the first non-termini edge. It is to be appreciated that these material options for the structuring layer apply to all of the examples and embodiments described herein.

FIG. 5A is a schematic perspective view. FIG. 5B is a schematic perspective view of a portion of the web material structuring belt 100 of FIG. 5A.
Each strip 400 may have a major axis 440 that is disposed parallel to, substantially parallel to, aligned with, or substantially aligned with the machine direction MD, such that the angle 441 between the major axis 440 and the machine direction MD may be in a range of from -5 degrees to 5 degrees, or about -5 degrees to about 5 degrees, or about -4 degrees to about 4 degrees, or about -3 degrees to about 3 degrees, or about -2 degrees to about 2 degrees, or about -1 degrees to about 1 degrees, or about 0 degrees, or 0 degrees.
It is to be appreciated that since the cross direction CD is perpendicular to the machine direction, the value of the angle 442 between the major axis 440 and the cross direction CD follows mathematically based on specification of the angle 441 or vice versa. For example, the angle 442 between the major axis 440 of each strip and the cross-direction CD may be 90 degrees, or about 90 degrees, or in a range of from about 85 degrees to about 90 degrees, or about 85 degrees to about 90 degrees, or about 86 degrees to about 90 degrees, or about 87 degrees to about 90 degrees or about 88 to 90 or about 89 to 90.

Optionally, it is possible to apply an associating material, bonding layer or modifying material to the support layer. According to various embodiments, it is possible to initiate the orthogonal wrap by positioning the structuring layer and the support layer in contact with one another so that the first side of the first structuring layer wrap non-termini edges align with the support layer first MD edge. According to various embodiments, it is possible to wrap the length of structuring layer fully around the endless support layer, until the structuring layer passes over the first termini edge. With the structuring layer overlapping itself, it is possible to cut through both layers with a cut 5 degrees from perpendicular with the non-termini edges of the structuring layer material, to create an abut seam on a 5 degree angle. Optionally, the seam may be cut to have a gap, abut, or overlap, or any combination of seam types. Optionally the seam may be cut parallel to the cross direction or up to 45 degrees from parallel to the cross direction of the support layer. According to various embodiments, it is possible to treat the entire first orthogonal wrap of structing material in contact with the support layer to bond the two layers. Next, it is possible to increment a new length of structuring material layer over 1/8” to create a gap seam between the second non-termini edge of the first wrap and the first non-termini edge of the second wrap. According to various embodiments, it is possible to place the termini edge of the second wrap approximately 1 inch further in the machine direction than the first wrap termini seam. Optionally the first and second seams may be in line or up to 10 feet apart. According to various embodiments, it is possible to maintain parallel placement of the second structuring layer wrap with the edge of the support layer and with the first wrap second non-termini edge. When this wrap of structuring layer overlaps with itself, it is possible to cut through both structuring layers with a cut 5 degrees for perpendicular with the non-termini edges of the structuring layer material, to create an structuring layer abut seam on a 5 degree angle. Optionally, the seam may be cut to have a gap, abut, or overlap, or combination of seam types.

According to various embodiments, it is possible to trim any excess structuring layer that extends past the support layer. Optionally the structuring and support layer may be treated to bond the layers after all the wraps have been completed by temporarily affixing the orthogonal wrap termini edges across the belt with tape until the bonding process is begun.

Alternatively, the angle 441 may be from less than 0 degrees to greater than -90 degrees, or less than about 0 degrees to greater than about -90 degrees, or about -3 degrees to about -805 degrees, or about -6 degrees to about -70 degrees, or about -8 degrees to about -60 degrees, or about -10 degrees to about -50 degrees, or about -12 degrees to about -45 degrees, or about -15 degrees to about -35 degrees, or about -18 degrees to about -25 degrees, or about -20 degrees to about -25 degrees, or about -22.5 degrees.
It is to be appreciated that since the cross direction CD is perpendicular to the machine direction, the value of the angle 442 between the major axis 440 and the cross direction CD follows mathematically based on specification of the angle 441 or vice versa. The angle 441 may vary for adjacent strips 400 and even in a case where a single strip 400 is repeatedly wrapped around the support layer 200 the angle 441 may vary for adjacent portions of the same strip 400.

As best illustrated in FIGS. 5B, 6B, 7B, and 8B, but as is applicable to all embodiments described herein, a gap seam 602 may have a width spanning the distance between adjacent strips 400.

The gap width GW may be from about 1/64 in (0.0397 cm) to about 2 in (5.08 cm), or about 1/32 in (0.0794 cm) to about 1 in (2.54 cm), or about 1/32 in (0.0794 cm) to about 0.75 in (1.905 cm), or about 1/16 in (0.1588 cm) to about 1/2 in (1.27 cm). The gap seam 602 may effectively become part of the overall structuring layer 300 in that it may be used to add a texture, a contour, a protrusion, a trough or a shape to a material disposed on the web material structuring belt 100.
As will be appreciated by those having ordinary skill in the art, various embodiments solve a variety of problems associated with winding belts. Providing winding belts from a narrower width structuring layer may provide material, cost, and pattern opportunities versus a full width structuring layer. Heretofore, winding belts, tended to create more seams that may create a higher probability for a discontinuity that is disadvantageous for a commercial-scale process or a commercially-acceptable product. It is has been discovered that a controlled gap seam, especially on the increased seam lengths of the non-terminal portions, will not have high thickness or low permeability issues that lead to the process and product problems. Various embodiments may reduce discontinuities so as to minimize process and product discontinuities that may lead to needing to run lower speeds or making bad product.
Various embodiments may control the type of seams so that they are predominately gap seams. Various embodiments may control where and how the seams in the machine direction MD and the cross direction CD are located using similar or disparate sized pieces of structuring strips. Various embodiments may employ gapping seams to create a “fire break,” where using structuring layer strips that remain independent of contact from each other, prevents a tear, hole, delamination, or other failure in the structuring layer from continuing to grow across the entire belt. Various embodiments may spirally wind the structuring strips in the cross direction CD, thus isolating individual segments across the machine direction MD, which may be the primary direction of strain for the belt. Without being bound by theory, it is thought that by segmenting the strips and keeping them independent of each other, the MD strain can be carried by the support layer, thus reducing strain on the structuring layer and any association, associating layer or bonding between the support and structuring layer. According to various embodiments, the gap seam may be part of the overall pattern of continuous or discontinuous structuring layers. According to various embodiments, a continuous pattern layer, where there is a continuous network of structuring layer material forming a pattern, may enable a semi-continuous overall pattern by separating the continuous network strips with a discontinuous gap seam, while a discontinuous pattern layer where the structuring layer material is not a continuous network may enable maintaining a discontinuous overall pattern by creating a continuous discontinuous network with the gap seam.
