SECTION B — PERFORMING OPERATIONS

SHAPING

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

|  | B31 |
Note(s) 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 Fulltext... Hierarchy... Expanded...D21J. 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 Fulltext... Hierarchy... Expanded...B65H.

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