Note(s) 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. Sub-class Fulltext... Hierarchy... Expanded...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 Fulltext... Hierarchy... Expanded...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. Fulltext... Hierarchy... Expanded...F16, takes precedence.
