Abstract: Metallic wire for spinning machinery has improved wear resistance of its teeth portion, which results in an improved grinding cycle and in an improved service life of the metallic wire. The wire has a quench hardened part on the whole teeth portion (except the valley bottom parts) which is formed by applying laser beams to the teeth portion according to the method of manufacturing the metallic wire for spinning machinery according to the present invention.

Abstract: A traveller for spinning made of hard drawn steel wire or alloy steel wire, having at least at the surface of a part which makes contact with a ring a ceramic coated layer. The ceramic coated layer consists of one or plural layers selected from a layer of carbide, nitride, oxide, boride or the like. The traveller with a ceramic coated layer has high wear resistance, runs stably for many hours, prevents frequent yarn breakage and has longer service life.
