ABSTRACT:
A press structure wherein die pads are movable within die sleeves and wherein the die pads are recessed within the die sleeves initially for receiving material slugs. A suitable mechanism is provided which permits the die pads to be returned to positions beyond their starting positions so as to effect the complete removal of a formed article from its respective die sleeve to facilitate transverse removal of each formed tubular body. The stop mechanism next functions to move the die pad back to the original starting position ready to receive thereon another material slug.
