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.
