ABSTRACT:
Manufacturing of a soft metal sheath formed of aluminum or copper, for example, is improved by suitably selecting the apparatus composing the shaping means employed therein and arranging the capstan and the sinking die in a novel manner. The apparatus selected is made from a wear-resistant synthetic resin such as a molybdenum bisulfide-included nylon. The sheath is manufactured from a metal tape of aluminum or copper through the working stages of applying a cylindrical tube shaped from the tape onto a cable core, butt welding the seam, and then reducing the diameter of the metal tube to connect it to the core.
