ABSTRACT:
In a device for intermittent straightening of wire there are independent drives for wire feed and the straightening rotor. The speed of rotation (v.sub.2) of the straightening rotor varies essentially synchronously to the feed rate (v.sub.1) of the wire. To cut the wire (t.sub.4) the wire and rotor are stopped. According to the invention the direction of rotation of the rotor is reversed between successive working cycles.
