ABSTRACT:
An end stop attaching apparatus has a pair of punch arms pivotally mounted on a punch holder on a shaft rotatably supported on a frame for angular movement about its own axis between end stop applying and supplying or loading positions, the punch arms having a pair of clinching punches, respectively, on their ends for supporting an end stop therebetween. A punch actuator is operatively mounted on the punch holder and is coupled with the punch arms for moving the punches toward and away from each other. The punch actuator is activated to enable the punches to clinch the end stop about a longitudinal edge of a stringer tape in the end stop applying position, and to enable the punches to receive an endmost end stop from an end stop supply in the end stop supplying or loading position.
