Abstract
A device for the perforation of a ductile and/or tacky sheet material includes a frame, pressing tool, a stamp provided with at least one hole, as well as a drive element suspended in the frame for causing the pressing tool and the stamp to move toward each other and away from each other respectively. The pressing tool is provided with an end face and the stamp with a die-edge surrounding the die-hole, which can be caused to act cooperatively with the end face of the pressing tool. The lateral dimensions of the end face are greater than the lateral dimensions of the die-edge, whilst the end face comes into contact with the die-edge essentially around the entire periphery thereof, or the end face and the die-edge enclose a gap with a fixed lateral dimension essentially around the entire periphery thereof.
