ABSTRACT:
A die assembly for extruding a cover of a thermoplastic material over on plurality of bare or previously covered wires. The assembly comprises a two-part die body which holds between the parts a pair of removable cylindrical distributors, a removable wire guide and a removable die plate. The distributors are spaced from each other and the wire guide and the die plate are on opposite sides of the space between the distributors. Manifolds in the body parts supply heated thermoplastic material to flow channels on the peripheries of the distributors, and such channels extend to the space between the distributors. The wire guide has tubular passageways equal in number to the number of wires to be covered, and the die plate has an opening or openings dimensioned to correspond to the exterior dimensions of the cover or covers to be applied to the wires.
