Abstract

The paper punch consists essentially of a lower part (1) equipped with side cheeks (2) and of a pressure plate (3) articulated on the side cheeks (2). Pressure is transmitted between the pressure plate (3) and hole punches (4) by means of a pressure bar (5) which is parallel to the pivot axis (32) of the pressure plate (3), bears with its upper edge against the pressure plate (3) and on its lower edge (53) has two downwardly pointing pressure studs (52) engaging into cup-like recesses (71) of the hole-punch heads (7) and being supported pivotably with their tip against the bottoms of these. <IMAGE>
