Abstract
A reciprocally driven device is provided for forming a smooth inwardly convex flange-bearing edge-groove or -corrugation onto the open end of a metal container. A punch is moved axially to secure the container in a receiver, to move at least two cheeks towards the axis of the punch and to compress a resilient pressure-cushion about the periphery of the punch to form the flange-bearing edge-groove in the open end of the container. The device is particularly useful on an extrusion press which forms the drawn metal hollow body of the container.
