ABSTRACT:
An apparatus for forming a self-locking patch type fastener which includes carrier means for moving a plurality of threaded metal fasteners along an arcuate path, clamping means associated with the carrier means to clamp the fasteners to the carrier means, movable resin transfer means having a fastener contact surface, and the transfer means being positioned to move the contact surface into contact with the fastener as the fastener is moved in an arcuate path past the transfer means. The speed and direction of movement of the contact surface relative to the carrier means during contact between the contact surface and the fastener is such as to provide an even transfer of resin from the contact surface to deposit a plastic patch thereon. Unclamping means are positioned with respect to the carrier means to unclamp the threaded fasteners after deposit of the plastic patch thereon and conveyor means then convey the fasteners away from the carrier means.
