Abstract
A method and apparatus are disclosed and can be used to fabricate a complete container end closure including an inwardly tipped cover hook located along the peripheral extremity. The apparatus and its use in performing the method are unique in that one tool does all the forming to produce the complete end closure. More particularly, the cover hook is preformed by a first tool operation and then finally formed by a subsequent step wherein the preformed end is reformed to a final configuration in a step which is completely independent of the first tool.
