Abstract

A wire winding system includes a capstan assembly for drawing wire at a substantially constant speed and a wind-up unit turntable adapted to receive a spool upon which wire is adapted to be wound. Between the capstan assembly and the wind-up unit turntable is an adjustable wire wind-up tension control system for a plurality of wire gauges. The tension control system comprises dancer means including a dancer pulley, variable weight means, including a chain with a plurality of weights affixed to the chain, and wire gauge selection means, operatively connected to the dancer means and the chain for positioning the chain to apply the predetermined weight for a selected one of the plurality of wire gauges so that a predetermined tension is placed in the wire. A linear sensor is operatively connected to the dancer means for sensing the relative position of the dancer means and providing a signal. The wind-up unit turntable is driven by a variable torque motor which is operable in response to the signal from the linear sensor to vary the torque supplied to the wire winding turntable.
