Abstract
In a machine for reducing the cross-section of a number of wires by drawing each of them through a respective series of dies of decreasing diameter, a corresponding series of individual capstans is used for drawing each wire through its series of dies, and each one of several drive shafts supports at spaced positions along its length the capstans of a respective drawing stage of each series. Each capstan is driven by the shaft on which it is mounted, and the drive mechanism for the shafts can be adjusted, by presetting or otherwise, to give different peripheral speed ratios to the capstans, to suit different die sets and/or to compensate for wear. The capstans are mounted between bearings supporting the shafts, and the drive mechanism is located outside the bearing at the relevant end of the shaft. Preferably mechanism coupling adjacent shafts alternates between the two ends of the machine.
