Abstract: A shed-type coil winder is disclosed in which a shed form is supported against rotation within a rotating wire feed envelope. Rotation of the shed form is prevented by an eccentric drive. The eccentric drive includes a wire support rotating about a first axis and an eccentric ring rotating about an eccentric axis spaced from and parallel to the first axis. The eccentric ring is driven by a parallelogram-type linkage so that it rotates with the flyer support in a uniform manner. The eccentric ring engages an eccentric cam on a form support to hold the form support against rotation while the flyer support and the eccentric ring rotate. A window is provided in the eccentric ring through which a wire guide extends with clearance. Consequently, the eccentric drive does not interfere with the rotation of the wire guide system. A jump actuating system is connected to the form support system to axially move the form in a stepwise manner.

Abstract: A coil winding system is disclosed in which wire directing shrouds are installed in a stator where the winding is performed to direct the wire of the coils into the proper position within the stator. An automated system provides a loading gripper head for picking up an unwound stator at a pick-up position on a supply conveyor and for transferring such unwound stator to a loading-unloading position on an indexing table. A shroud gripper subsequently installs the shrouds in the stator at the loading-unloading position and the stator and shrouds are locked with respect to the table. The indexing table then transports the unwound stator to a winding position and simultaneously moves a wound stator to the loading unloading position. The shroud gripper then removes the shrouds and an unloading gripper transports the wound stator to a discharge conveyor.

Abstract: Apparatus for winding coils in the slots of an externally-slotted dynamoelectric machine core member comprises a flyer and a support for the core. Shroud member portions are disposed within the path of rotation of the flyer. 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 outwardly 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.degree.

Abstract: Disclosed is the apparatus and method for depositing a winding of varying depth along the teeth of a stator. The necessity for complex motion of the winding head is avoided by moving the head in conventional reciprocating fashion and then introducing winding turn distributing elements from outboard of the stator. The distributing elements are moved radially inward between the path of the wire-dispensing component of the winding head and the end faces of the stator tooth receiving the winding. The distributing elements are moved in a series of reciprocating strokes of decreasing length as the winding head moves through its winding path, thereby distributing the windings in increasing depth toward the base of the stator tooth receiving the winding.
