Abstract: A device for embossing braille characters on an embossable substrate includes the combination of a feed device advancing the substrate and embossing head for embossing dots on the substrate. The embossing head is movable relative to the feed device to emboss horizontal lines of dots on the substrate in predetermined patterns. One horizontal line of Braille characters can be printed on a substrate by the embossing of three horizontal lines of dots on the substrate, the substrate being advanced between the horizontal lines of dots by the feed device.
