Abstract
A wire tensioner maintains wire in a winding machine at a substantially constant tension during the process of winding coils for electrical components such as armatures. The tensioner has a pulley wheel that is driven by a bidirectional drive unit. During operation, the pulley wheel either feeds wire toward a workpiece or draws wire back, depending on the nature of the tension correction required.
