ABSTRACT:
This disclosure relates to a system for the continuous high speed production of non-metallic (NM) sheath cable from bare and insulated single strand conductors continuously produced in a high-speed tandem wire drawing and insulation operation. An automated material handling system is provided for transporting and conveying wire pack containers from coiling strands where the bare and insulated single strand wires are coiled into the containers to a station where the wires are continuously paid-out overhead from the wire pack containers and brought together in a jacketing line where PVC coating compound is extruded thereon. A sheathed cable is then coiled and packaged in a continuous manner. The depleted wire pack containers are then transported back to the coiling stands to close the material handling loop. The system is controlled by a programmable computer which controls the delivery of wire pack containers to various ones of a plurality of conveyor lines on a demand basis.
