Abstract
A wire positioning mechanism and method for positioning a start wire of a coil bundle from the bottom of the coil bundle to the top of the coil bundle during winding of the coil. The mechanism includes a pivotable and retractable arm with a clamp assembly, a contacting finger, and a wire hook on one end thereof. The start wire is first deflected into the space between the two separated sections of a coil form by the contacting finger. The wire is then lightly clamped. The coil is then wound on the coil form so that the start wire will be positioned inside the coil. The wire hook is then activated to reposition the start wire through the coil bundle and out over the top of the coil bundle. The start wire positioning mechanism is then moved out of the way of the coil and the winding operation is completed.
