Abstract
Methods and apparatus for reforming drawn and ironed containers are disclosed. The invention permits improvements in bottom profiles by radially expanding arcuate segments against the inner leg that connects the bottom rim of the container to the center panel. The reforming introduced by the present invention permits containers to be constructed of a lighter gauge material without suffering from any loss in strength. The container being reformed is seated on a flat surface and a radially expanding die is used in conjunction with a tapered mandrel to reform the bottom profile. Most preferably, the reforming tool of the present invention is incorporated into a container necking mechanism.
