B31D3/0223 - CPC Classification

Classification description:

Making articles of cellular structure, e.g. insulating board honeycombed structures, i.e. the cells having an essentially hexagonal section Making honeycomb cores, e.g. by piling a plurality of web sections or sheets

Sub-classes:

B31D3/023 » {by cutting webs longitudinally into strips, piling these strips and uniting them along lines perpendicular to the cuts} 6
B31D3/0246 » {Plane webs having essentially longitudinal adhesive strips being folded transversely into stacks or being cut transversely into sections which are piled, e.g. zigzag-folding the webs preceding the cutting} 2
B31D3/0269 » {Forming piles by winding a web on a reel } 1
