Abstract: Ends for cans are made in a single press, eliminating the need for separate shell and conversion presses, balancers, track work, and other equipment, as compared to existing can end manufacturing systems, while reducing floor space and capital investment requirements for installation of a new can end line. A sheet of end material or stock is introduced into the press and fed to a series of work stations. The sheet is maintained in a substantially continuous and void free state as the work stations perform forming operations on the sheet of material to form one or more ends therein. After the forming operation is complete, the end is ejected from the press. The maintenance of the sheet of material in a substantially continuous and void free state permits precise movement of the sheet through the press, and registration of the sheet relative to the tooling in the press.

Abstract: The product and method of manufacturing a tab having a rivet island window and adapted to be secured to a container end, including the steps of forming a first dimple at a first end position of the window and a second dimple at a second end position of the window, formed as depressed regions of metal residing outside the central plane of the metal. The method includes punching a first blank in the first dimple and a second blank in the second dimple, and subsequently bending the edge regions around the first and second blank to form a bend of the metal away from the central plane. The central region of the window is formed between and joining the blanks, and a rivet opening is formed, adapted to receive a rivet for staking the tab to a container end.
