Title:
COIL WINDING DEVICE, COIL WINDING METHOD, AND METHOD FOR MANUFACTURING ROTARY ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2021/024538
Kind Code:
A1
Abstract:
A nozzle holder (65B) of this coil winding device (60) comprises, on a tensioner (62) side: a first insertion part (77b1) that causes a bundle wire (42) to pass therethrough toward a spindle shaft (65C) side and that can restrict the circumferential rotation of the bundle wire (42); a second insertion part (77b2) that can grip and release the bundle wire (42) inserted into the first insertion part (77b1) toward the spindle shaft (65C) side; and rotation mechanisms (7uR, 7dR) that rotate at least one of the first insertion part (77b1) or the second insertion part (77b2) in the circumferential direction of the bundle wire (42) in a state in which the first insertion part (77b1) restricts the circumferential rotation of the bundle wire (42) and the second insertion part (77b2) grips the bundle wire.
