PROCESS DEVELOPMENT FOR STRANDING AND PLYING OF METALLIC YARNS.
Abstract
A manufacturing process and associated equipment for the twisting, plying and cabling of small diameter, high strength, heat resistant metal wires into multifilament yarns were developed. The equipment is capable of twisting wires with diameters from 0.0005 in. and smaller, to 0.0015 in. into yarns with 0.1 to 50 turns per in. twist. Textile twisting equipment was evaluated, and it was established that some ring-twisters can be adapted to the twisting of fine wire. The list of manufacturers who produce these machines is given. The shortcomings of the standard commercial textile ring-twisters for wire twisting are discussed. Modifications are given that must be made to overcome these shortcomings. The design of the machine constructed is given. The design incorporates the necessary type creel, wire and yarn guides, and an electronic stop motion that detects the rupture of a single 0.0005-in.-diameter metal filament. (Author)
