ABSTRACT:
A fastener mounting apparatus includes a punch which is connected with a base to be mounted on one section of a press and a fastener mounting section which is movable relative to the punch during operation of the press. A conveyor is operable to conduct fasteners to a loading station in the fastener mounting section. An ejector assembly applies force against a slug cut from a member to move the slug away from a die. The ejector assembly includes a pin disposed in a coaxial relationship with the punch and a spring assembly offset to one side of the punch. A force transmitting member or rocker arm transmits force from the spring assembly to the ejector pin. A loading force applied against the fasteners by the conveyor is terminated during a portion of each operating cycle of the press to reduce the force urging the fasteners toward the loading station and prevent jamming of fasteners at the loading station. In one embodiment of the invention, a latch or retainer assembly is provided to hold the mounting section in a position in which the punch blocks movement of the fasteners to the loading station.
