| Title of Invention | A SPINNING MACHINE TRAVELER |
|---|---|
| Abstract | The present invention provides a spining machine traveler comprising: a base material consisting of hard steel wire or alloy steel wire;and a nitrogen compound layer provided on the outer side of the base material;characterized in that: said traveler further comprises a sulfide layer provided on the outer side of the nitrogen compound layer. |
| Full Text | The present invention relates to a spinning machine traveler, and more specifically, to a spinning machine traveler which is ro be used in a spinning machine, such as a ring spinning machine (ring spinning frame) or a -ring twisting machine (ring twisting frame), and which is formed into a predetermined shape by using a hard steel wire or an alloy steel wire. 2. Description of the Related Art Recently, in ring spinning frames also, there is a demand for an increase in speed to achieve an improvement in productivity, and an ultra-high-speed spinning operation at a spindle RPM of not less than 20,000 rpm has been carried cat. As the spindle rotational speed increases, the speed at which the traveler circles on the ring also increases. When the circling speed of the traveler increases, the frictional resistance between the ring and the traveler increases, and wear the ring and the traveler is expedited, resulting in a rather short service life. Further, when the frictional resistance between the ring and the traveler increases, a large quantity of frictional heat is generated, making the parts themselves subject to damage and deformation and adversely affecting the take-up thread. SUMMARY OF THE INVENTION The present invention has been made in view of problem inherent, in "Chef prick-r art, Therefore, it is an object of the present invention to provide a spinning machine traveler which, even in the case of an ultra-high-speed spinning operation at a spindle rotational speed of 25,000 rpm or more, makes it possible to do away with running-in operation at the start of sliding treatment consists o£ a treatment: method in which so rising treatment and nit riding treatment are executed simple temperature. WHAT IS CLAIMED IS: ' 1. A spinning machine traveler comprising: a base material consisting of hard steel wire or alloy steel wire; a kitchen compound layer provided on the outer side of che base material; and a sulfide layer provided on che outer side of the nitrogen compound layer. 2- A spinning machine traveler according to Claim 1, further comprising a solid lubricant material layer provided on the cuter side of the sulfide layer. 3. A spinning machine traveler according to Claim 1, wherein the nitrogen compound layer and the sulfide layer are formed through sulphonitriding treatment. 4, A spinning machine traveler according to Claim 3, wherein the sulphcnitriding treatment consists of a gas sulphonitriding treatment. |
