A machine for automatically assembling the tubular rivet and pin of a blind rivet assembly. The tubular rivets and pins are fed from supply hoppers along a pair of chutes, one of which carries a sequence of rivets and the other of which carriesa sequence of pins. The chutes terminate at a pair of rotatably indexable turrets which have peripheral configurations adapted to pick off and carry the rivets and pins from the ends of their respective chutes. The turrets are rotatably indexed to bring the rivets and pins sequentially to an assembly station at which the pin and rivet are axially aligned with each other and in readiness to enable the pin to be driven into and through the tubular rivet. A hammering mechanism is employed to drive the pin through the sleeve to a finally assembled configuration with the sleeve and the assembled pin and rivet then are ejected from the machine. |
