Abstract

The letter perforator has a lower part composed of a base plate (1) which forms the punching die and two edge side parts (11, 11') which are connected to the said plate and on which there are formed tabs (12, 12') which contain the punch guides (13, 13'). The entire lower part is punched from a piece of sheet metal. The web forming the punching die is formed by a part (2) which is cut away from the base plate (1) on three sides of a rectangle, is initially bent approximately vertically upwards and is then bent horizontally backwards. By means of lateral tabs (9, 9') which rest on edges (10, 10') of the side parts (11, 11') which are bent upwards at right angles, the punch pressure is transferred to the lateral parts (11, 11') which contain the bearings (16, 16') of the pressure plate. Deformation of the perforator is avoided in this manner, despite the thinness of the sheet metal from which the base plate (1) is formed. <IMAGE>
