Process for the machining of stamping parts photochemically etched out of a carrier base, and stamping webs obtained therefrom

摘要

The invention relates to the machining of cutting (stamping) edges which are etched photochemically out of a carrier base and by means of which labels consisting of label material adhering releasably to a supporting web are to be cut (stamped) as a result of the rolling of the cutting edges of the label material, wherein the cutting edges are given a triangular cross-section having fluted sides by milling by means of a frustoconical milling cutter engaging the longitudinal sides of the cutting edges and rotating about its axis. The invention also relates to cutting edges obtained by the process.
