Abstract
An actuator for a redraw sleeve that operates independently of the ram drive mechanism is provided. The actuator utilizes an eccentric journal coupled to a drive shaft of a servomotor. The servomotor is structured to provide its output shaft with a variable rotation speed so as to accommodate the need for the redraw sleeve to be in selected locations at specific times. Further, the redraw sleeve includes a collapsing redraw cylinder to allow the redraw sleeve to dwell in a forward position.
