Abstract
Abstract An apparatus for forming magnetic core winding end turn assemblies includes a center-mounting member to receive the cores thereabout. Arcuate outer jaws are positioned to be outside the end turn assembly and arcuate inner jaws are positioned to be inside the end turn assembly. The jaws are connected to cams outside the end turn assembly, the inner jaws by arms positioned axially beyond the end turn assembly, which are actuated for moving the jaws toward each other to confine the end turn assembly. A forming ring is movable relative to the core between the jaws for applying a compressive force on the end turn assembly to form the assembly into a compact mass. There is a stop, movable relative to the forming ring for regulating the amount of movement of the forming ring. The apparatus has two forming units, each having inner jaws, outer jaws and a forming ring. One forming unit is axially movable relative to the centermounting member to allow insertion and removal of cores.
