ABSTRACT:
An apparatus, for assembling a pair of fastener elements of a garment fastener, includes a safe-confirmation member mounted on a lower end of a vertically movable supporting rod supported by a frame in parallel relation to a punch-carrying plunger, and a drive means for moving the supporting rod vertically between an uppermost position in which the safe-confirmation member is disposed around a punch, and a lowermost position in which the safe-confirmation member is disposed around the die in the absence of the operator's finger or a tool near the die. Upon arrival of the safe-confirmation member at the lowermost position, a detecting means produces a command signal to start lowering of the punch toward the die.
