Method and device for punching thermoplastic material or the like

摘要

The invention relates to a method and a device for punching thermoplastic material, having cutters which are heated in a controllable manner and the toothed cutting edges (2) of which are pressed during punching into a plastic support of a counter tool. To reduce the energy expended and to simplify the design, it is proposed that the cutters (1) be electrically heated in such a way that an operating temperature of 80-150 DEG C is produced only in the region of their cutting edges (2). <IMAGE>
