近年、リング精紡機、リング撚糸機等の紡機においても
生産性向上のため、高速化が指向されている。そして、
高速化を進める上でトラベラの摩耗が重要な問題となっ
ている。(Prior Art) In recent years, speeding up of spinning machines such as ring spinning machines and ring twisting machines has been sought to improve productivity. and,
Traveler wear has become an important issue as speed increases.

れており、紡機のスピンドルの回転が比較的遅いときに
はあまり問題はないが、スピンドルの回転数が２０００
Ｏｒｐｍを越える場合には摩耗の点などで問題が生じ
、対応できなくなってきた。Conventionally, carbon tool 1 (J Is G-4401SK material) has been commonly used as the material for travelers for spinning machines, and although there is no problem when the spindle rotation of the spinning machine is relatively slow, 2000
When exceeding Orpm, problems arise in terms of wear and the like, and it has become impossible to cope with the problem.

膜（層）を形成したものとが提案されている。Therefore, as a means to improve the wear resistance of the traveler,
For example, the traveler disclosed in Japanese Patent Publication No. 57-4728 etc. is made entirely of alloy steel with excellent wear resistance,
A traveler disclosed in Japanese Patent Application Laid-Open No. 61-6333 and the like has been proposed in which a wear-resistant film (layer) is formed on at least the surface of the portion that contacts the ring.

えで重要となる。As shown in FIG. 7, the winding tension W of the yarn Y, the balloon tension T, and the centrifugal force C are applied to the spinning shaft traveler 1 during the winding operation, and the resultant force is the contact pressure with the ring 2. Acts as. It is important that the traveler 1 slides on the ring 2 in a constant posture in order to prevent yarn breakage and deterioration of yarn quality.

、その間機台の稼動効率が低くなり生産性が低下すると
いう問題がある。As shown in Figure 8.9, in the early stages of use of the traveler 1, the contact area with the ring 2 is small, resulting in an unstable gliding position, which is disadvantageous in that thread breakage occurs frequently and fuzz is generated. . In order to eliminate this inconvenience, conventional travelers require a break-in period at low speed during the initial stage of use until a shape that conforms to the ring surface is formed, during which time the operating efficiency of the machine becomes low and productivity decreases. There is a problem.

不安定な期間が長くなるという問題がある。(Problem to be solved by the invention) In order to cope with the increase in machine speed, if the traveler is made of a wear-resistant material, or if a wear-resistant film is formed on the traveler surface through surface treatment, the wear resistance will be reduced. Until the shape is formed, the traveler slides under high surface pressure, resulting in progressive wear. Further, due to the wear resistance, it takes a long time to form a conforming shape, and there is a problem that the period during which the traveling posture of the traveler is unstable becomes long.

きを確認する必要がない。As in the past, press working using a molding machine can be applied to manufacture the traveler, and a mold that forms a recess corresponding to the shape that fits in with the ring is used as the press mold. The steel wire or alloy wire that serves as the base material is formed into a predetermined shape by press working using the above-mentioned mold, and then heat treatment is applied as necessary, and further surface treatment is applied for the purpose of improving wear resistance and heat resistance. conduct. Instead of forming the recesses 3 only at one location on the traveler 1 as shown in FIG. 1, they may be formed at two symmetrical locations as shown in FIG. When two recesses 3 are formed, there is no need to check the orientation of the traveler 1 when attaching it to the ring.

される。(Function) During the winding operation of the spinning machine, the traveler 1 moves to the flange 2 of the ring 2.
Slide at high speed on a. As shown in FIG. 2.3, the traveler of the present invention slides with the entire concave portion 3 in contact with the flange portion 2a of the ring 2 from the beginning of its use, so the contact area between the traveler 1 and the ring 2 becomes large. The gliding posture becomes stable. Therefore, unlike conventional travelers, it is possible to use the machine at high speed from the beginning without providing a period of slow spinning operation. In addition, since the surface pressure exerted on the traveler is reduced even in the initial stage of use, the wear rate of the traveler is reduced, and the usable period of the traveler is significantly extended.

It is possible to improve productivity by increasing productivity. Also,
Even in the early stages of use, the surface pressure exerted on the traveler is reduced, and the speed at which the traveler wears out is reduced. Therefore, surface treatment can be applied to a traveler made of ordinary steel wire, without having to make the entire traveler of wear-resistant material. Even if it is a material, it has an excellent effect of being able to withstand use for a sufficiently long period of time.
