Abstract: Machines for writing braille type having two opposing rows of embossing units each with a support holding a punch-forming stamp guidable between an inactive position and a pushed-out embossing position with abutment against a die member disposed opposite the embossing unit. An electromagnet for each unit controls the stamp with a displaceable plunger. The rows of units are arranged for synchronous movement towards and away from each other in a direction substantially at right angles to the path of movement of a sheet for receiving the type. Each opposing support forms coherent die-punch pairs. Each support has a double-armed rocker which with one end abuts an impressing end of the embossing stamp while the other end projects outwards so that on movement of the support towards the path of the sheet, it is guided substantially at right angles towards the end of the plunger of the electromagnet when said plunger is pushed out.
