Abstract
A stator coil winding machine for winding a wire around a neck portion of each pole. A spindle through which the wire is inserted is reciprocated in an axial direction thereof. A nozzle is provided at one end of the spindle, and the nozzle is inserted through a slot of a stator core by the axial reciprocation of the spindle. The spindle is reciprocated axially and is reciprocatively rotated at a predetermined angle at opposite ends of the axial reciprocation. Thus, the wire is supplied from the nozzle and is wound around the neck portion. The nozzle is pivotally mounted on the spindle so as to be tiltable in the axial direction of the spindle. In another embodiment, a nozzle swinging device is provided to tilt the nozzle in a direction counter to an advancing direction of the spindle.
