Abstract
An improvement in devices for placing prewound coils and insulating wedges into slots of dynamoelectric machine stator cores, for example in manufacturing electric motors, is disclosed with the device having a wedge making apparatus including a drive, an arrangement for cutting insulating wedges from a strip of insulating material, and an arrangement for forming the wedges into a magazine for subsequent insertion into stator core slots. The improvement provides for the quick conversion of the device from operation on one stator core configuration to operation on a different stator core configuration without removing any bolts from the device with the improved wedge making apparatus actuating arrangement including an elongated bipartite material cut-off drive bar for coupling the drive to the cutting arrangement, an elongated bipartite wedge forming drive bar coupling the drive to the arrangement for forming the wedges into the magazine with both the bipartite drive bars being separable into two parts to allow removal of the cutting and forming arrangements from the device without disturbing the drive. Each bipartite drive bar includes a clamping bolt received in a slot of one bipar…
