Abstract
An apparatus and a process for continuously producing an assembly of headed fasteners of uniform length. The fasteners, fixed in either an equally spaced apart parallel relationship or in a contiguous parallel relationship, are produced by providing at least one strand of wire in straight and untwisted form, cutting the wire into headless fasteners of uniform length, transferring the headless fasteners onto a guide track in parallel, adjacent alignment, collating the headless fasteners to form a continuous web thereof, conveying the continuous web of headless fasteners into a clamping block and then forming a head from one end of the fasteners to form the headed fastener. The apparatus for producing the headed fastener assembly includes means for providing the wire in straight untwisted form, means for cutting the wire into headless fasteners, means for transferring the headless fasteners onto a guide track in parallel adjacent alignment, means for collating the fasteners a conveyor to convey the continuous web of headless fasteners to a head-forming means, and severing means for selectively cutting the continuous web to produce the assemblies or clips of headed fasteners.
