Abstract
A device for making a master plate for printing braille includes a support table on which a master plate material is positionable. A punch is disposed on a first side of the master plate material. A punch die is positioned in alignment with the punch, and is arranged on a second side of the master plate material. A punch driver is connected to the punch, and is activateable to move the punch toward the master plate material. A shifter arrangement is provided for changing a relative position of the master plate material to the punch and the punch die. A controller is operatively connected to the shifter and the punch driver for controlling an operation of the shifter and the punch driver. A data supply arrangement is coupled to the controller, and supplies punching data thereto. The controller acts upon the punching data to cause the shifter to move the plate material relative to the punch and the punch die, and cause the punch driver to be actuated to punch the plate material at locations corresponding to raised braille dot positions.
