METHOD FOR PREPARATION OF BRAILLE PRINTING SHEET

摘要

PURPOSE:To provide a printing sheet with a high productivity through simultaneous formation of braille holes and spacer holes on the printing sheet by feeding the braille printing sheet puncher with a braille inputting tape provided with a bit for braille forming signal and a bit for functional signal. CONSTITUTION:In the production of a braille printing sheet by punching braille holes on the sheet with a puncher, a braille inputting tape comprising a braille forming signal and a line changing signal into a braille printing sheet puncher. Then, braille holes are formed on the sheet set on the puncher according to the braille forming signal while spacer holes are formed thereon according to the line changing signal in the functional signal. This eliminates the need for providing the spacer forming holes in the making of the braille printing sheet.
