ABSTRACT:
A system and process for use when forming lift-tab can end assemblies wherein each can end assembly includes a lift tab having a smooth side, an opposite roughened side and a hole extending between the sides and a can end having a protruding shaft integrally formed in one face thereof utilizes a guide system for inverting a strip of metal stock through about 180.degree. as the strip is conveyed between one workstation at which lift tabs are pre-formed therein and another workstation at which the tabs are punched, so as to sever the tabs from, the strip. The punched tabs are thereafter collected in a stacked relationship and directed to a position adjacent still another workstation at which the tabs are attached, by way of the tab holes and the can end shafts, to the can ends. By inverting the strip of metal stock during the assembly-forming process, the tabs are inverted from a smooth-side-down condition to a smooth-side-up condition for attachment to the can end.
