Abstract:
A punch whereby decorative cutouts with clearly cut peripheries can be produced from a perforation process, wherein the punch comprises:a die defining an outer profile and at least one inner profile; a cutter comprising an inner leading edge configured to mate with the outer profile of the die, an outer trailing edge, an inclined periphery extending between the inner and outer edges, and at least one central cutting edge configured to mate with the at least one inner profile of the die; a resilient ejector formed as a loop and received in a recess surrounding the die, and configured to mate with the inner leading edge of the cutter, and having a top face equal in height to an upper face of the die; and means for combining the die and the cutter, whereby the cutter can reciprocally extend through the die; the improvement residing in that after the central cutting edge and the leading inner edge have cut peripheries in a material , a remaining portion of the material is held in place by the resilient ejector until the trailing edge and the inclined periphery have descended past the upper face of the die to complete the perforation process.
