ABSTRACT:
A clamping unit has a pair of clamping jaws movable toward each other by manually operable threaded rods to clamp a slotted hollow body such as a separable bottom stop member for a separable slide fastener on a beaded edge positioned between the clamping jaws. A central presser presses the slotted hollow body against shoulders of the clamping jaws to shape the slotted hollow body. The clamping jaws and the presser are adjustably limited in their coacting movement so as to handle slotted hollow bodies of various sizes. The clamping jaws and the presser are spring-loaded so that they will be automatically retracted out of an operating position upon release.
