ABSTRACT:
A wire forming apparatus for making springs with coiled body portions and end loops is modified by providing a digital controlled wire feeding accessory. The accessory permits the normal mechanical feeding of the wire and tooling to be interrupted for desired intervals during the spring forming process thereby allowing digital controlled wire feeding to occur. The digital controlled wire feeding enhances the normal operation of the apparatus by allowing specified lengths of wire to be added to the coiled body portions and/or end loops of the manufactured spring.
