ABSTRACT: FLYER WINDER FOR EXTERNALLY SLOTTED DYNAMOELECTRIC MACHINE CORE MEMBER Apparatus for winding coils in the slots of an externally- slotted dynamoelectric machine core member comprises a flyer and a support for the core arranged so that the flyer axis extends through the peripheral edge of the core midway between the two slots in which a coil is to be wound and parallel with and midway between the core sides. A shroud member is disposed within the path of rotation of the flyer, the shroud having portions adapted to extend outwardly over each side of the core to overlay the sides of the core portion between the two slots around which a coil is to be wound. The shroud portions have outer and inner ends with the inner and outer ends being joined by a radially outwardly facing, outwardly tapered surfaces. Two rotatable wheel elements are provided on opposite sides of the core and having peripheral surfaces adjacent the shroud portion surfaces. The outer surface of each shroud portion has an out- wardly extending groove therein and the peripheral surface of the respective wheel element extends into the groove thereby inhibiting rotation of the shroud member. Each of the wheel elements has a cut-out portion which communicates with its peripheral surface and which has a radially extending trailing edge which faces the respective core side as the wheel element is rotated in a direction to move the edge from the inner to the outer end of the respective shroud surface. The wheel elements are rotated in opposite directions and the cut-out portions are phase-displaced by 180° to permit passage of the flyer as the same rotates about the shroud member so that wire is initially wound around the shroud portions and alternately engaged by the leading edge of a wheel element cut-out portion and pulled thereby outwardly over the outer end of a shroud portion to guide the wire into and toward the back of the two slots.
