Abstract

A fixed strip steel punch form for punching out a fixed pattern corresponding to the form of the steel strip 22 in each of a number of stacked compressible layers of material 34 comprises a vacuum system for vertically reducing the stacked height of the compressible layers of material 34 without disturbing the sides and before punching out, and for maintaining the compressed state during continuous or phased punching operations. In a method for punching out compressible layers of material 34 a cutting edge 22 and the compressible layers of material 34 to be punched out thereby 22 are arranged in an airtight collapsible chamber and the air is evacuated from the said chamber, so that it collapses, following which the compressible layers of material 34 are pressed against the cutting edge 22, so that this is pressed through the compressible layers of material 34, as a result of which each of the layers is punched out in a set pattern corresponding to the form of the strip 22. <IMAGE>
