Abstract
Systems and methods for winding wire are disclosed. A system includes a wire take-up unit and a wire tensioning unit. The take-up unit includes a rotating mandrel and a wire directing device, the wire directing device arranged to cause the wire to be wound in a figure-eight configuration on the rotating mandrel to form a coil having many layers of wire. The wire tensioning unit applies tension to said wire as it is wound, and applies a first amount of tension to a predetermined amount of wire constituting at least a first two layers of the coil, and a second amount of tension to the wire beyond the predetermined amount. In one embodiment, the wire tensioning unit includes digital self-relieving air regulator pneumatically coupled to and controlling a pressure in said pressurized chamber of a pre-lubricating cylinder that is coupled to the wire being wound.
