摘要： In order for a coil winding head, preferably to be reinforced by the baked-lacquer process, to be compression-molded with no need for preliminary pre-positioning by tape-wrapping and with no damage to the winding wires, a form shell apparatus is provided with a form core, which radially confines the coil end forms shape on the inside, with a radially advanced confining form shell divided into at least two parts in the circumferential direction. This multi-part shell radially confines the coil end turns on the outside. A compression form shell axially advanceable against the coil end turns confines the coil end turns in an axial direction. It has, on its inner and outer circumferential surfaces, integrally molded guide fingers, which extend axially in the direction of the coil end turns to be shaped. Corresponding guide grooves are molded into the form core and the confining form shell, into which guide grooves the guide fingers extend. Furthermore, the compression form shell has axial inner and outer compression fingers, which extend into the gaps of the coil winding head and press the winding of the said coil winding head in the radial or tangential direction. After assembly, the apparatus safely secures and protects the coil end turns in the desired position and shape.
