ABSTRACT:
End tooling for forming easy open can ends has cooperatively-engageable upper and lower tooling defining a plurality of stations. Each station has appropriate punches and dies for progressively converting shells indexed by conveyor into easy open can ends. The tooling is adapted to convert ends of multiple diameters. The punch caps and die caps at each station have cylindrical bodies sized to engage and align a turned edge of a shell. The caps also have one or more arcuate grooves in the end face thereof for receiving the turned edge of ends having a diameter smaller than that of the cap.
