ABSTRACT:
A generally dome-shaped end closure for a receptacle, such as, the bottom end wall of a beverage container is roll-formed in a closely coordinated sequence of steps wherein the receptacle is fixed in position so that the external surface of the end wall to be formed is disposed in facing relation to a yieldable support, and rotatable bearing surfaces are simultaneously advanced into engagement with the end wall while being continuously rotated about a common axis whereby to form one or more annular ribs in the end wall while forcing the end wall to assume a generally convex or dome-shaped configuration as it is expanded outwardly against the yieldable support. A roll-forming apparatus for carrying out the method of the present invention permits a succession of end walls to be roll-formed on a revolving turret which carries a plurality of roller assemblies, each roller assembly defining the rotatable bearing surfaces which are rotated by a spindle drive, the spindle drive being axially advanced by a cam member as it is rotated to cause the associated roller assembly to advance axially through the interior of each receptacle for the roll-forming operation followed by retraction away from the receptacle whereupon the yieldable support is operative to release the can from its fixed position for unloading into a separate stacking area.
