  • Wire twisting method and apparatus
    Patent number: 4102117
    Abstract: A twisted pair of wires is produced by drawing two insulated wires from two supply reels while rotating one wire supply reel about the other. A capstan and tachometer measure the linear rate at which the twisted pair is being drawn. The output of the tachometer is controllably and variably divided and used to control a power inverter that drives a motor which rotates the one wire supply reel about the other. The variable ratio between the linear wire movement and the rotary or twisting movement is controlled by a random generator producing a series of numbers representing length per twist of the twisted pair, between fixed limits.
