Title:
WIRE TWISTING DEVICE AND METHOD OF MANUFACTURING TWISTED WIRE
Document Type and Number:
WIPO Patent Application WO/2019/106925
Kind Code:
A1
Abstract:
This wire twisting device is provided with: a core wire moving mechanism which causes a core wire to be moved in an axial direction; a spool which rotates to unwind a wire material wound thereon; a revolving mechanism which causes the spool to revolve around the core wire; and a rotation drive mechanism which causes the spool to rotate to unwind the wire material. The wire material unwound from the spool is wound helically around the periphery of the core wire as the core wire moves in the axial direction due to revolution of the spool. The wire twisting device is provided with a control device which comprises: a wire material speed acquisition unit which acquires a speed of the wire material being wound around the core wire; and a rotation drive mechanism control unit which controls the rotation drive mechanism so that the speed of the wire material that has been acquired by means of the wire material speed acquisition unit has a predetermined value.
