Abstract
Abstract Apparatus for developing one or more coil groups of electrically conductive wire. The apparatus includes a coil turn-forming assembly having a jump form portion and a snap-out form portion. The jump form portion includes a plurality of turn-gauging steps with an interruption formed at one side. The snap-out form portion is supported adjacent to the interruptions on the turngauging steps and includes a corresponding number of snap-out winding form plates, each having a fill-in winding section for spanning one of the associated interruptions on the jump form portion. The apparatus also includes a flyer for placing wire on the coil turn-forming assembly to generate turns and a jump means for locating a turn-gauging step of the jump form portion in the path of the wire being wound by the flyer. Concurrently as the jump means locates a turn-gauging step in the path of the wire wound by the flyer, a snap-out plate is extended to place a fill-in winding section in alignment with its associated interruption of a turn-gauging step. The turn-gauging step of the jump form portion and its associated fill-in winding section cooperate to provide a form for winding or generating turns of a predetermined length for receipt in a coil group accommodating means or device. Preferably, the coil group accommodating means is comprised of spaced curved blades defining turn receiving slots. The spaced curved blades and corresponding fill-in winding sections of the snap-out plates have associated mating curved surfaces whereby, when a snap-out plate is engaged with a curved blade, the entry of the turns of a coil being generated into the corresponding turn receiving slot is facilitated by the mating curved surfaces. Thus each coil is developed directly in the coil group accommodating means as the turns for the coil are generated about the coil turn-forming assembly. Also, the jump form portion and the snap-out plates may be supported for movement in essentially a vertical direction, and the curved blades are supported in alignment with the snap-out plates so that force of gravity facilitates the removal of the turns from the coil form assembly. Additionally at least part of the jump form portion is movable relative to the snap-out portion during the turn-generating operation for selectively varying the lengths of successive turns. A coil group is developed in the coil group accommodating means by producing a plurality of serially connected wound coils of a coil group in the coil group accommodating means. Thereafter the coil group may be inserted directly from the coil group accommodating means into preselected slots of a stator core.
