Abstract
Apparatus for reforming an end wall of a container comprises a pair of cooperating pads 10, 11 cooperable to clamp the wall firmly on a central axis of the pads and wall, and a cluster of work rolls 12 arranged around the pads so that when a clamped wall is entered into the profiled rolls 12 relative rotation as between the rolls 12 and protruding edge of the wall 1 brings about progressive deformation of the periphery of the wall. The apparatus may be modified to form a peripheral curl on a can end or tighten the folds of a can bottom integral with a drawn side wall.
