Abstract: A machine includes a feed system for moving fasteners to a track-type fastener injector system and a pusher for moving the fasteners along the track. A rivet ejector assembly comprises a pair of bomb bay-type doors which support a portion of the track feed system and a mechanism for recognizing misfed rivets as they approach the bomb bay doors. The bomb bay doors are rotated about their longitudinal axes so that opposing inner surfaces of the bomb bay doors pivot away from each other, along with the track portion, permitting the fastener to fall or be blown therethrough, ejected from the injector system.
