【The invention's effect】
According to the twisting device of the first aspect of the present invention, there is no contact between the twisted wires due to the rotational centrifugal force of the flyer, and thus the strands constituting the twisted wires are plated or coated or Even if an aluminum wire is used, there is no danger of the plating being stripped or the coating or the aluminum wire being damaged. Furthermore, since the stranded wire moves between the pair of left and right arcuate divided halves, there is an advantage that the quality of the stranded wire is stabilized without being affected by wind pressure due to rotation of the flyer.
[0018]
According to the twisting device of the second aspect of the present invention, in addition to the above, the moving twisted wire after the completion of the predetermined twisting is pressed by the first roller row and the second roller row in the residual stress removing means of the twisted wire. Since it is meandered and held so that the twisted state does not collapse, when the stranded wire is cut, the twist does not return from the cut portion.
