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 along a curved guideway to a receiving station. Prior to being engaged by 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 formation on the feeder maintains the cup in engagement with the registry formation while the cup is initially engaged by the ram during forward movement thereof.
