Abstract

The mechanism, for soft materials such as plastics or metal foil, has a feed unit, a series of blanking punches and a sepg. unit to separate the individual tabs. Dies form a continuous stiffening rib in the feed stock before it reaches the punches. The stiffening rib in the feed stock renders the stock easier to handle in the feed mechanisms and the punches. USe of a cam driven feed unit provides ample time to feed the stock between the feed operations.
