B31F1/24 - CPC Classification

Classification description:

Mechanical deformation without removing material, e.g. in combination with laminating; Corrugating; Corrugating combined with laminating to other layers Making webs in which the channel of each corrugation is transverse to the web feed

Sub-classes:

B31F1/242 » {the corrugations being obliquely inclined to the web feed } 4
B31F1/245 » {by feeding the webs in a channel larger than the thickness of the webs by means of rollers, e.g. involving prefolding} 0
B31F1/247 » {by reciprocating members} 2
B31F1/26 » by interengaging toothed cylinders {cylinder constructions } 24
B31F1/29 » by making use of rods, e.g. co-operating with a toothed cylinder {combined with uniting the corrugated web to flat webs } 1
B31F1/30 » Tools secured to endless chains {e.g. toothed belts; combined with uniting the corrugated web to flat webs} 4
