B42 BOOKBINDING; ALBUMS; FILES; SPECIAL PRINTED MATTER
Description
Class B42 covers mechanical and manual processes for binding books and related document assemblies, including techniques for collating, folding, and securing sheets or signatures. It encompasses the manufacture of albums, filing systems, and bound documents, as well as specialized printed materials with particular structural or functional requirements. The classification includes equipment, machines, and methods for producing finished bound products, but excludes the underlying printing processes themselves (covered under B41) and general paper or material processing operations. Adjacent classes address paper manufacturing, printing technology, and unrelated document handling or storage systems.
