Abstract

The invention relates to a perforating device with a perforating device under part (10), at least two punch units (20) threaded on a bar (34) at an adjustable distance from each other, and a pressure lever (18) pivotably mounted on the under part (10) and acting against the backward end surfaces (54) of the hole punch (56) of the punch units (20) to displace the hole punches (56) counter to the force of, in each case, one return spring (48). In order to permit a slight displacement of the punch units (20) within the perforating device and simple exchange of the assembly bar (34) fitted with the punch units (20), the hole punches (56) strike, in their upper end position and under the action of their return springs (48), against an upper end stop (52) of the respective punch unit (20), while between the perforating device under part (10) and the pressure lever (18) there is arranged at least one spring element (60, 62) bridging the punch units (20), which lifts the pressure lever (18) away from the backward end surfaces (54) of the hole punches (56) and holds it under prestress against an upper end stop. As a result, the assembly bar (34) can be removed from the under part (10) as a structural unit, jointly with the punch units (20) threaded thereon. <IMAGE>
