High Speed Embossing of Braille Masters

The left drawing shows a computer-operated printing mechanism for forming Braille master plates 1. The latter are employed on a standard Braille embossing press, not shown, to form a final Braille manuscript having raised characters.

In operation, an ink-character, as distinguished from a raised-character, manuscript which is to be converted to Braille is prepared using a computer- based editing program in computer 2. The ink-character manuscript, stored electronically in computer 2, is converted to a raised-character manuscript, also electronically stored, using conversion programs. The raised-character manuscript in computer 2 is then used to control the printing mechanism and form the Braille plates 1.

The printing mechanism includes one or more printing elements 4 which strike plates 1 which is positioned in carriage 3. Elements 4 form the raised characters on plates 1 in a manner similar to the manner that a typewriter types out an ink-character.

Plates 1 are in the form of sheets or rolls of foil-like material such as electrolytic copper, aluminum, other malleable alloys, plastics or papers. The material can be prepared in continuous-sheet form with horizontal perforations to permit folding and stacking or, alternatively, can be prepared as individual page- size sheets mounted on a special continuous form carrier paper.

As indicated in the right drawing, an element 4 strikes plates 1 simultaneously forming male portio...
