SHAPING
 B31
MAKING PAPER ARTICLES; WORKING PAPER (making layered products not composed wholly of paper or cardboard B32B; handling thin material, e.g. sheets, webs, B65H)
 B31

Note(s)

  1. The word "paper" in this class is to be interpreted as covering material worked in a manner analogous to paper, e.g. plastic sheet materials, laminated materials or metal foils. This class does not include making articles directly from paper pulp, which is covered by D21J.
  2. This class is to be understood as restricted to adaptations or associations of handling sheets, webs, or blanks peculiar to paper-working, e.g. bag or box making, machinery. Handling sheets, webs, or blanks of wider applicability, irrespective of whether described or claimed only for paper-working machinery, is to be regarded as of a more comprehensive nature and as such classified in B65H.
 B31B
MAKING BOXES, CARTONS, ENVELOPES OR BAGS (incising, scoring, in general B26D 3/08; combined making and filling B65B)
 B31B

Note(s)

  1. In this sub-class, envelopes or bags are regarded as being essentially flexible containers, the final shape of which is determined by their contents. Boxes or cartons, on the other hand, are regarded as being essentially rigid or semi-rigid containers, the final shape of which is not determined by their contents. The term "boxes or cartons" is to be interpreted as including bags formed similarly to cartons, trays with upstanding side-walls, barrels, tubes and cups, other than articles formed by winding.
  2. If any further subdivision of any of groups B31B 3/00-B31B 41/00 becomes necessary, the new sub-groups to be provided will correspond exactly in wording and sub-group numbering to the relevant sub-groups of group B31B 1/00.

 B31C
MAKING WOUND ARTICLES, e.g. WOUND TUBES (characteristics relating to the working of plastics B29)
 B31C

Note(s)

The term "winding" in this sub-class means forming two or more complete convolutions.


 B31D
MAKING OTHER PAPER ARTICLES (making articles from wood fibre B29J 5/00; making layered products not composed wholly of paper or cardboard B32B; making cardboard and paper D21F, D21H, making articles from wood pulp D21J)
 B31D

Note(s)

This sub-class is to be understood as covering making, otherwise than by winding, articles other than boxes, cartons, envelopes, bags, and tubes from paper, other than from paper pulp.


 B31F
MECHANICAL WORKING OR DEFORMATION OF PAPER OR CARDBOARD (cutting, trimming, in general B26; incising, scoring, in general B26D 3/08; making layered products not composed wholly of paper or cardboard B32B; multi-ply material of paper or cardboard, its manufacture D21H)
