ABSTRACT:
An apparatus to expand a diameter of a can or other article comprises a forming turret that includes a stop plate and a forming tooling. The stop plate is configured to be adjacent a dome-end of a can to restrict motion of the can; the stop plate is axially movable relative to a turret axis of rotation. The forming tooling includes a plate and an expansion tool axially movable relative to the turret axis of rotation. The plate includes an opening through which the tool passes. The expansion tool is configured to move into an open end of the can to expand the diameter of the can.
