|  | B31 |
Note(s) This class covers subject matter restricted to adaptations or associations of handling sheets, webs, or blanks peculiar to paper-working, e.g. bag or box making, machinery. This class does not cover: making articles directly from paper pulp, which is covered by Fulltext... Hierarchy... Expanded...D21J; handling sheets, webs, or blanks of wider applicability, irrespective of whether described or claimed only for paper-working machinery, which is regarded as being of a more comprehensive nature and is covered by Fulltext... Hierarchy... Expanded...B65H. In this class, the following term is used with the meaning indicated: "paper" covers material worked in a manner analogous to paper, e.g. plastics sheet materials, laminated materials or metal foils.
