Abstract: An apparatus is provided for extending and retracting a redraw sleeve of a container bodymaker and for electromagnetically holding the redraw sleeve in its extended position against a container blank. A linear motor is disposed between two bulkheads and is interconnected with the redraw sleeve through one or more actuating rods. An electromagnet assembly is disposed proximate to a redraw die and, when activated, holds the redraw sleeve against the container blank while a reciprocating ram forces the container blank through the redraw die. The linear motor and the electromagnet assembly are axially disposed relative to the redraw die and the bulkheads to provide adequate access to the nose of the ram, the redraw sleeve and other components.

Abstract: Domer apparatus includes a housing having a cavity therein; an inner die being disposed in the cavity and being disposed around a longitudinal ram axis; an outer die being disposed in the cavity, being disposed around the longitudinal ram axis, and being disposed circumferentially around the inner die; second, third, and fourth springs being disposed in the cavity radially outward from the longitudinal ram axis, being circumferentially spaced-apart, and operatively engaging the inner die; and an air spring being disposed outwardly of the housing distal from the outer die, and providing a resilient force to the outer die along a plurality of paths that include a plurality of push rods, that are disposed radially outward of the longitudinal ram axis, and that extend longitudinally past the second, third, and fourth springs.
