 B41J

Note(s)

  1. This subclass covers:
    • manually controlled power-operated apparatus or apparatus of this type with additional control by input of recorded information, e.g. on punched cards or tapes;
    • 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, printing heads.  [5]
  2. This subclass does not cover:
    • electrical features of apparatus controlled by record carriers or electric signals and of interest apart from the "print-out" features of said apparatus;
    • apparatus controlled by record carriers or electric signals, as a whole.  [5]
  3. In this subclass, the following term is used with the meaning indicated:
    • "paper" covers also similar flexible copy material;  [3]
    • "printing material" covers both paper and temporary record carriers from which records are transferred to a paper, but does not cover printing masters, e.g. formes.  [5]

 B41L

Note(s)

  1. This subclass does not cover 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, or to addressing machines or like series-printing machines, which are covered by subclass B41F.
  2. In this subclass, as indicated by the references, groups B41L 15/00 and 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 are classified in subclass 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.
  3. In this subclass, the following terms are used with the meanings indicated:
    • "manifolding" means the obtaining of several copies simultaneously by means of pressure-sensitive layers when making an original;
    • "duplicating" means 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.
