ABSTRACT:
Apparatus for forming elongated metal cans from relatively short cups by utilizing a reciprocating ram to drive the cups one at a time through a die pack, is provided with a continuously rotating feeder that transfers the cups from the exit of a gravity feed chute to a receiving station where each cup is indexed for engagement by the ram as it moves forward in its working stroke. The feeder rotates through one complete revolution for each forward-return cycle of the ram and during each revolution thereof a pocket in the feeder receives a cup from the chute, which cup then moves downstream through a guideway to a receiving station. Prior to being seated in a registry formation at the receiving station, the cup is engaged by a stripper that removes the cup from the feeder pocket. The feeder continues to drive the cup toward the registry formation while the cup is being stripped from the feeder pocket. A tensioner device and a formation on the feeder maintain the cup seated fully on the registry formation during the initial engagement of the cup by the ram while the latter moves forward in its working stroke.
