Abstract

122,773. Dresden, G. May 30, 1918. Cupped articles; eyelets.-A punching machine for forming cupped articles from sheet metal which is fed by a step-by-step motion under a series of punches is described as for making eyelets. The strip A is fed under a series of punches F of decreasing diameters, the dies having reciprocating bottoms formed by pins I supported by and adapted to be moved by a cam such as the shaft J. Beyond the punches F is a bottom piercing punch M and a severing punch R, the eyelets falling through the hole T. The strip is pressed upwards between these dies by a pair of spring-pressed pins P.
