ABSTRACT:
End plates are clamped around a circular magnetic core and tightened to produce two straight parallel sides. Side plates are placed adjacent to the remaining curved portions of the core. The side plates are forced together with the aid of a jack and frame structure. When the desired rectangular shape has been obtained, bolts are attached to the side plates to maintain the shape of the core until it has been annealed. The frame structure includes a pair of tracks which help to guide the side plates during the forming process.
