PURPOSE: To enable removal of the torsion remaining in a twisted wire in the stage of producing the twisted wire by providing a secondary fabricating device between the turn roller and capstans between an overtwister and a winder.

CONSTITUTION: Strands for a twisted wire are drawn out of plural supply spools 1 attached to a tortoise-shaped cradle 4 and are given twists by the rotation of flyers 3. The torsion opposite from the twisting direction is generated on one side in this case and therefore the twisted wire past guide rollers 5 is further twisted down and untwisted by as much as the number of the torsion by an overtwister 6. The twisted wire is taken off by capstans 7 via a turn roller 8 and is taken up on a take-up spool 11 via a traverse roller 10. A secondary fabricating device 9 is placed in the tension-free position between the turn roller 8 and the capstans 7 to bend and set alternately the twisted wire at the radius of curvature of 50W10 times the diameter of the twisted wire, thereby removing the torsion remaining in the twisted wire.
