Title:
WIRE TWISTING APPARATUS AND METHOD FOR MANUFACTURING TWISTED WIRE
Document Type and Number:
WIPO Patent Application WO/2017/022418
Kind Code:
A1
Abstract:
A wire twisting apparatus (10) is provided with a shaft member (11) provided with a nozzle (11b) through which a wire (32) let out from a spool (31) is inserted, a shaft member rotation mechanism (12) that causes the shaft member (11) to rotate about a center axis (C1), a plurality of orbiting bodies (23) that are provided around the shaft member (11) and that orbit the shaft member (11) by means of rotation of the shaft member (11), a rotation inhibition mechanism (25) for inhibiting rotation of each of the orbiting bodies (23), and a rotation driving mechanism (40) controlled by a control device (8) to rotate the spool (31). The spool (31) is rotatably supported by the orbiting body (23) so that the center axis (C3) of the spool (31) can be orthogonal to the center axis (C1) of the shaft member (11), and the rotation driving mechanism (40) is provided in the orbiting body (23).
