B41B MACHINES OR ACCESSORIES FOR MAKING, SETTING, OR DISTRIBUTING TYPE; TYPE; PHOTOGRAPHIC OR PHOTOELECTRIC COMPOSING DEVICES (photographic devices in general G03)
Description
B41B encompasses machinery and equipment for the complete manufacturing and handling workflow of typographic characters, including type casting, setting, spacing, and sorting systems. It covers mechanical type composition devices, photocomposition systems, and photoelectronic typesetting equipment used in traditional and modern printing preparation. This subclass also includes the physical type characters themselves and auxiliary apparatus for type distribution and management. Related printing processes and the actual printing machines themselves fall under adjacent B41 subclasses rather than B41B.
