Description
B41G covers specialized printing apparatus designed for applying metallic finishes, linear decorative elements, and edge treatments to paper and similar substrates. The subclass encompasses bronze printing machines (which deposit metallic powders or foils onto printed surfaces), line printing equipment for creating decorative borders and rules, and apparatus for edging or finishing sheet edges. It also includes auxiliary perforating devices integrated with printing systems to simultaneously punch holes or cut decorative patterns while printing. These technologies were historically significant in commercial printing, bookbinding, and decorative finishing operations.
