Abstract
Apparatus for crimping a noncircular edge portion of a cup-shaped container or for rolling a bead on a noncircular edge portion of such a container includes a plurality of forming rollers supported on a rotary tool carrier for rotation with the tool carrier and relative to it. A roller follower associated with each forming roller and engaged within a stationary cam track causes each forming roller to travel in a noncircular path about the axis of the tool carrier as the tool carrier rotates about its axis. The tool carrier moves in an axial direction generally toward and away from a mandrel or receiver supporting the container to move the forming rollers into and out of forming engagement with a noncircular edge of the container.
