Abstract:
Apparatus for forming a twisted electrical cable comprising:a first plurality of stationary payoff reels each wound with a length of stranded bare wire conductor having upstream and downstream ends;means for simultaneously paying off the stranded bare wire conductors from said reels;first accumulator means arranged downstream of said payoff reels for accumulating a portion of the stranded bare wire conductor from each payoff reel;extruder means arranged downstream of said first accumulator means for application of an insulation material to each stranded bare wire conductor as it passes through the extruder means;means arranged downstream of said extruder means for cooling the insulation material applied to each stranded bare wire conductors and forming a plurality of insulated conductors, each insulated conductor having a longitudinal axis;second accumulator means arranged downstream of said cooling means for accumulating a portion of each insulated conductor;take-up means arranged downstream of the second accumulator means and means rotating said take-up means about a first axis for twisting each insulated conductor about its longitudinal axis and simultaneously twisting said insulated conductors about one another to form said twisted electrical cable; andmeans rotating said take-up means about a second axis for taking up said twisted electrical cable onto said take-up means.
