Abstract: The present invention provides a ball-bat repairing apparatus to repair, for example, softball and baseball bats, in which particularly aluminum ball-bats which have been deformed from repeated use are returned to substantially their original diameter along the longitudinal extent of the ball-bat barrel. The ball-bat repairing apparatus has a frame which holds a two-piece die therein. The two-piece die has a top half and a bottom half in which a pair of semi-cylindrical die inserts are secured. The die inserts are made of relatively soft material, e.g., plastic so as not to damage the aluminum bat during repair. A compression member is threadedly received through the frame and is located in mechanical cooperation with a first of the die halves.

Abstract: A metal container lid having an apertured design with rolled edges is stamped by a method and apparatus incorporating a cushioning pad between a die and the metal sheet, which is then stamped with a perforating punch.
