Abstract: A method and apparatus is disclosed which reduces the complexity of the apparatus needed to accomplish the cross linking reaction in the process of coating a synthetic resin material onto a conducting wire. A rotary orifice is provided just down stream of the extruder and just upstream of the forming die. The rotary orifice imparts a compressive and a shearing stress to the resin to thereby increase the temperature uniformly. The increase in temperature assists in bringing about the cross linking reaction.

Abstract: An automatic cable winding apparatus comprises a traverse arm mounted to the traverse block sliding on a traverse base that guides cables to be wound on the drum and provided near the top thereof with guide rollers guiding said cables while supporting them from the upper and the lower sides thereof and a presser roller pressing the cables sideways, a device giving pressing force to said traverse arm, proximity switches detecting that the cables are wound up to the vicinity of the flange of the drum, a rotation angle detector which causes said traverse base to stop by the detection signals generated from said proximity switches and detects the rotation angle of the drum, another device for quickly advancing and retracting said traverse block relative to the flanges of the drum when said rotation angle detector detects that the drum has been rotated by a predetermined angle, and a device for raising the traverse apparatus by the height of the outer diameter of the cable every time a new layer of cable is wound
