ABSTRACT:
The present invention is an assembly and method for continuously manufacturing fasteners. A die press actuated at a first speed receives the contoured wire into a die having a piercing element for piercing an aperture and a cutting element for cutting a fastener from the wire. A guide receives the fasteners from the die press and a drive unit engages the fasteners oriented by the guide and conveys the fastener to an elevated height relative to a tapping device. The guide redirects the fasteners by a first router. The fasteners are gravity fed into the first router and redirected to one of the tapping devices. Each tapping device has a tapping element for forming internal ribs in the aperture of the fastener. The tapping devices each actuates at a second speed that in aggregate is generally equal to the first speed of the die press.
