APPARATUS OR DEVICES FOR MANIFOLDING, DUPLICATING OR PRINTING FOR OFFICE OR OTHER COMMERCIAL PURPOSES

ADDRESSING MACHINES OR LIKE SERIES-PRINTING MACHINES printing presses or machines for industrial purposes B41F; stamps, stamping or numbering devices B41K

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.

In this subclass, as indicated by the references, groups B41L15/00 and B41L17/00 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.

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.

In this subclass non-limiting references (in the sense of paragraph 39 of the Guide to the IPC) may still be displayed in the scheme.
