Note(s) This sub-class includes manually controlled power-operated apparatus and apparatus of this type with additional control by input of recorded information, e.g. on punched cards or tapes. It also includes the "print-out" features of apparatus controlled by record carriers or electric signals in so far as these are of general interest, e.g. impression, inking, line-spacing mechanisms, but excludes electrical features thereof and such apparatus as a whole.

|  | B41L |
Note(s) The term "manifolding" is to be interpreted as meaning the obtaining of several copies simultaneously by means of pressure-sensitive layers when making an original. The term "duplicating" is to be interpreted as meaning the obtaining of successive copies from a master, e.g. a hectographic image. "Stencilling" involves the use of a printing surface which is perforated to form the image, the ink flowing through the perforations on the copy material. As indicated by the references, groups Fulltext... Hierarchy... Expanded...B41L 15/00 and Fulltext... Hierarchy... Expanded...B41L 17/00 are intended to cover letterpress and lithographic printing apparatus only in so far as it is specially adapted for office or other commercial purposes, the general constructions or features of apparatus of these types being classified primarily in sub-class Fulltext... Hierarchy... Expanded...B41F. Constructions or features determining classification in these groups are, for example: ease of operation by clerical staff, cleanliness of operation in non-industrial environments, the use of printing surfaces constructed for the production of a limited number of copies. Constituent parts common to manifolding by means of pressure-sensitive layers or intermediaries, to apparatus or machines for duplicating or printing for office or other commercial purposes, and to addressographs or like series-printing machines Fulltext...
