Abstract

Braille characters are composed of dots arranged in the form of a matrix. In the process of embossing Braille characters, all embossing stamps of an embossing machine forming a given character are selected and caused to print simultaneously. Thus, embossing machines operate by embossing character by character.

Embossing Braille Characters

Braille characters are composed of dots arranged in the form of a matrix. In the process of embossing Braille characters, all embossing stamps of an embossing machine forming a given character are selected and caused to print simultaneously. Thus, embossing machines operate by embossing character by character.

It is now possible to obtain a substantial increase in the embossing speed by providing that, instead of embossing character-by-character, the characters are embossed step-by-step. Each step involves the simultaneous embossing of all horizontally aligned matrix dots of all characters of a line. The number of embossing steps for a complete line corresponds to the number of rows in the dot matrix.

Where the character matrix consists of three rows and two columns it is, e.g., possible to punch four Braille lines each including thirty-five characters into a punched card the rows of which correspond to the rows of the character matrix. The operation of embossing a line of characters is then performed in three steps each of which involves the reading out and embossing of one punched card row.
