Abstract

Rigid material 3, 5 and 6 is placed in the indents of a braille original and transferred to a duplication master substrate to form a braille duplication master. The braille duplication master is contacted under pressure, for example roller 11, with a depressionable member 10, Thereby duplicating the braille points of a braille original,

Rigid material 3, 5 and 6 is placed in the indents of a
braille original and transferred to a duplication master
substrate to form a braille duplication master. The
braille duplication master is contacted under pressure, for
example roller 11, with a depressionable member 10, Thereby
duplicating the braille points of a braille original,

A screen, with openings at intervals matching the two-
dimensional matrix of uniformly spaced rows of braille
points in the braille original, can be placed over the
original to achieve registration between screen openings and
indents of the original, The rigid materials can include
any material having rigidity sufficient to form indents in
the depressionable material selected for depressionable
member 10, Typical suitable rigid material include metals,
metal alloys, hard rubber, sand and rigid organic and in-
organic materials, The rigid material may have any shape,
spherical being preferred for convenience and standardi-
zation ease, For example, with screen openings of around
1,5 mm spherical shaped rigid material of about 1 mm is
preferred for braille originals typically having 1 mm

indent diameters,

Excess rigid material can be removed by brush, blade
scraper, air jet or other suitable means to produce the
braille original loaded with rigid material in its indents,

The duplication master substrate can have the rig...
