Apparatus includes pinch wheels that both advance wedge material stock and also substantially permanently form the stock material to precise dimensional tolerances by reducing the material thickness; means by which the formed material is retained in the formed configuration thereof; wedge severing means; and means for loading severed wedges into a wedge magazine. One of the pinch wheels is driven through a clutch-brake system arranged so that it may be driven unidirectionally only from a reciprocating drive arm. The wedges have precisely controlled dimensional tolerances and dimensional stability, with the result that the wedges lie squarely in stator core slots (when the wedges are inserted into such slots), and "wire over wedge" problems associated with skewed wedges in stator core slots are overcome. |
