Abstract
A wire straightener, and multiple preform rollers prepare a continuous length wire for further forming with multiple form rollers having multiple spaced apart notches on an exterior surface edge of the rollers. The notches cause a section of the wire to be non-formed. After the formed wire is fed to a gripper housing where the wire is cut to a predetermined length, the non-formed section is punched to create the fastener head. The end section of the fastener opposite the head is tapered and the finished fastener is ejected from the machine.
