Abstract
A method and apparatus for continuously forming cases from blanks using a rotary turret. Blanks are deposited near dies located on the turret. Each blank is centered on the rotary turret using an associated centering mechanism so that the blank is centered over the die. A punch aligned with the die is drives toward an extended position to push the blank through the die, thereby forming a case. The punch and centering mechanism retract as an ejector extends to remove the case from the die. A redraw sleeve coaxial with the punch strips the case from the punch to deposit the punch on the extended ejector. Subsequent turrets may be connected through transfer wheels to the first turret for performing redrawing operations until a case with the desired dimensions is obtained.
