B41L

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)

NOTE

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 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.

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.
