Since the plurality of strands are twisted together at the first twist pitch and the lengths of the center wire and the outer wire are fixed, the outer wire needs to be wound around the center wire at the second pitch, the length of the formed twisted wire becomes short due to twisting, the center wire does not change due to no winding, and a difference in length occurs between the center wire and the twisted wire. The length difference is cumulatively increased along with the increase of the length of the stranded wire, and when the length difference reaches a certain degree, the central wire can form a curved arch and can push against the outer layer to surround the wire during the arch, so that two results are formed, namely, the central wire arches to the outer layer, the excess length is released, and a product with non-round stranding is formed; and secondly, the outer layer monofilament is broken when the arch is formed, so that waste products are formed.
