03-AO-5348 METHOD AND APPARATUS FOR CONTROLLING THE LENGTH OF ROLLED WEDGES FOR DYNAMOELECTRIC MACHINES ABSTRACT OF THE DISCLOSURE 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 through the first drive link continues to travel along a fixed path.
