In apparatus for and a method of making a cable a zero twist machine 1 is connected to a double twist machine 2. A capstan 12 draws a wire pair through to the double twist machine 1 isolating the tension in the pair upstream of the capstan from that downstream of the capstan. A further capstan 17 enables the tension in the wire to be isolated from the tension in the wire at the point at which it is wound on a take up reel 18. By controlling the drives of both capstans 12 and 17, the tension in wire at entry to the double twist machine may be optimized. The provision of the two capstans enables wire to be metered into and out of the bow thus preventing of inhibiting looping of the wire out of the bow 16 of machine 2 under low tension. |
