PERFORATING; PUNCHING; CUTTING-OUT; STAMPING-OUT; SEVERING BY MEANS OTHER THAN CUTTING (details common to machines for severing B26D; drilling metal B23B, wood B27C, stone B28D, punching metal B21D; plastics, rubber B29C, B29D, B29H; making boxes, cartons, envelopes, or bags B31B; tailoring A41H; shoemaking A43D; surgery A61B; of glass C03B; of leather C14B; of tickets G07B)
 B26F

Note(s)

  1. This sub-class provides for perforating, punching, cutting-out, stamping-out, and for severing, by means other than cutting, non-metallic sheet material and metal foil in general and also for severing, by means other than cutting, other forms of non-metallic materials not otherwise provided for.
  2. Sub-class B26D provides for features specific to machines for cutting, perforating, punching, cutting-out, stamping-out, and severing by means other than cutting which relate to a requirement or problem of a nature which is not peculiar to a machine for these purposes, that is, details of, and arrangements for, operating and controlling such machines, although the realisation of such features may differ according to the kind of machine concerned. Sub-class B26D provides in general for such features even if the feature in any particular case is to some extent peculiar to, or is claimed only for, a machine designed for perforating, punching, cutting-out, stamping-out, or for severing other than by cutting. If the details or arrangements have no essential features specific to cutting, perforating, punching, cutting-out, stamping-out, or severing machines, the more general class, e.g. F16, takes precedence.
