ABSTRACT:
An assembly line for continuously manufacturing fasteners from a rod with a groove for receiving a wire for retaining the fasteners in a strip includes a receiver for receiving the rod. A die press is arranged to receive the rod from the receiver and includes a piercing member for piercing an aperture in each fastener and a cutting member for cutting each fastener from the rod. A tapping member provides ribs to an inner wall of the aperture formed in the fastener by the piercing member. An inspector inspects the internal rib formed into the inner wall of the aperture disposed in the fastener verifying exactness of the aperture and the rib. A wire inserter inserts the wire into the groove forming a strip of connected fasteners. The inserter receives the fasteners sequentially from the inspector after verification of the exactness of the aperture disposed in each fastener.
