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 ofa carrier base and by means of which labels consisting oflabel material adhering releasably to a supporting webare to be cut (stamped) as a result of the rolling of thecutting edges of the label material, wherein the cuttingedges are given a triangular cross-section having flutedsides by milling by means of a frustoconical millingcutter engaging the longitudinal sides of the cuttingedges and rotating about its axis. The invention alsorelates to cutting edges obtained by the process.
