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.

Abstract: A method of terminating a set of leads integral with a winding on a dynamoelectric machine stator assembly with the winding and the leads formed of magnet wire having a conductor with a dielectric material coating adhered in insulating relation thereto, and a set of dielectric tubes extend about the leads, respectively. To practice this method, the tubes are arranged in preselected positions with the free ends of the leads extending beyond one opposite end portion of the tubes, respectively. Each tube is melted through to sever a distal section from each tube adjacent its one opposite end portion while the insulating integrity of the dielectric material coating on the leads is maintained.

Abstract: The application discloses new modes of changing the length of pinch roller fed wedge material that involves transmitting motive power from a power shaft to a driven pinch roller through a power train that includes at least one pivoting lever, the effective length of which is quickly changed by moving a pivot shaft which supports such lever. Power is supplied through a first link from a main drive shaft to a pivoting slider, and then to a rocker arm or a lever which rocks about a pre-selected pivot point. Power is transmitted from such lever to a rack or other driving mechanism which then supplies motive power to a pinch wheel assembly. The pivot for the previously mentioned rocker arm is adjustable, and thereby the relative effective lengths of the rocker arm on either side of the pivot may be selectively varied in order to change the extent of rotary movement of the driven pinch roller even though the first drive link continues to travel along a fixed path.

Abstract: Methods and apparatus are disclosed for producing dynamoelectric machine coil groups or winding poles. A clamp device, relatively axially movable coil form and turn receiver, and relatively rotatable flyer are used, and interpole wire segments are established by intercepting, at a fixed location, a segment of wire extending between the form and flyer prior to complete cessation of relative rotation between the same.Intercoil winding segments are also accurately established. For example, an intercoil winding segment is deflected out of the winding plane and in a direction toward a subsequent winding form stage during the development of the last turn of a coil developed on the previous winding stage. Deflection of the intercoil winding segment is preferably accomplished substantially concurrently with advancement of the winding form relative to the turn receiver.
