ABSTRACT:
The present invention offers a machine which is capable of creating contrahelic wound harness sections existing with continuously disposed straight lay wire sections. The invention avoids the necessity of interposing electrical connectors between the contrahelic and straight lay sections thereby vastly improving the reliability and cost considerations of a complex multiwire harness. Pulleys are driven in synchronism by microprocessor-controlled stepper motors. The pulley winding the contrahelic layer may be moved transversely by a rack and pinion gear arrangement, the pinion gear being stepper motor driven by the microprocessor so that a correct transversal rate is achieved during contrahelic winding.
