It is also a procedure to specify for the production of this ring traveler.
  • a ring traveler has one made of iron material existing, uncoated core on the at least in the area of the treads with which he is on a ring of a ring spinning or ring twisting machine slides or in which the thread is guided, one if necessary has multi-part nitrided surface layer.
  • the core is heated to a temperature in the range from 450.degree. C. to 600.degree. C., preferably to a temperature close to 550.degree. C., and is kept in the temperature range mentioned for 3 to 60 hours, preferably for about 24 hours.
  • the nitrating agent can be supplied in the form of a gas, a liquid or a plasma, preferably consisting of NH 3 and N 2 parts. Areas in which no nitriding treatment should take place are covered, for example.
  • the nitrided edge layer of the ring rotor core consists of a connection layer without an additional diffusion layer, from a connection layer with additional, radially inner diffusion layer or only a diffusion layer.
  • the connection layer points preferably a thickness of 0.1 microns - 30 microns and the Diffusion layer to a thickness of 1 ⁇ m - 2000 ⁇ m.
  • the active medium preferably has, in addition to Nitrogen parts, sulfur and / or carbon parts on. By adding sulfur and / or carbon parts the coefficient of friction can be reduced. At the same time, the thicknesses of the connection layer and the diffusion layer can be matched as required.
  • connection layer When choosing small thicknesses of the connection layer there are only slight changes in the roughness of the Core surface.
  • the Surface of the ring traveler before and / or after the Nitriding treatment additionally polished. Ring traveler that are exposed to high chemical stress, are preferably post-oxidized.
  • the ring travelers according to the invention have significantly improved Operating characteristics, especially an increased one Runner service life and increased resistance to cutting at the thread passage.
  • the functionally very important Resistance to cutting in the thread passage with mechanical and / or chemical exposure was increased by 50% - 200% improved, resulting in an improvement in the quality of the processed yarn results. Because of the increased chemical resistance will also contaminate yarn avoided by corrosion products during processing previously developed and chlorine-containing fibers have so far occurred. Due to the good sliding properties, it is also little or no fiber lubrication required.
  • the ring traveler can also be done with less effort manufactured and possibly existing individual Requirements are adjusted.
  • Ring travelers according to the invention can be used in spinning mills as well as used in twisting factories. Your good Running properties, e.g. good gliding and less Wear, come together particularly advantageous with steel rings, but they can also on other rings, such as on sintered, burnished or coated rings can be used.
  • Figures 1a to 1f show ring travelers 10a, ..., 10f in various, already described in WO 99/49113 Configurations.
  • 1a and 1b are C-shaped Ring traveler 10a, 10b shown as they typically are T-flange rings from ring spinning or ring twisting machines be used.
  • Figures 1c to 1f show ear and hook-shaped ring traveler 10c, ..., 10f.
  • the Ring travelers 10c and 10d are placed on inclined flange rings, the ring traveler 10e on tapered and the Ring traveler 10f on vertically running flange rings used.
  • Ring travelers 10 or 10a,... 10f according to the invention can in the shown in Fig. 1a, ..., 1f or in any further refinements are produced.
  • a ring traveler 10 has one Iron material existing, uncoated core 20 on, at least in area 1 of the treads which he has on a ring of a ring spinning or ring twisting machine slides or in the area where the thread is led to a nitrided zone.
  • the thread passage lies in the areas marked with 4 Ring traveler 10a, ..., 10f.
  • the ring traveler 10 is at least partially one Subjected to nitriding treatment during which the core 20 Thermal energy and a nitrating agent as active medium is fed.
  • the ring traveler 10 preferably polished before nitriding.
  • the base material of the core 20 is preferably a unalloyed or low-alloy steel, preferably a nitriding steel.
  • a core 20 is preferably made from a tempered steel chosen during the nitriding treatment only negligible small size changes arise.
  • the base material of the core 20 also contains preferably nitride-forming elements such as chromium, vanadium, Aluminum, molybdenum, manganese and / or nickel.
  • the process parameters such as temperature profile (Ramp profile of heating, holding time and holding temperature, Ramp profile of cooling) and composition of the nitrating agent is the result of the nitriding treatment.
  • the core is heated in a furnace to a temperature in the range from 450.degree. C. to 600.degree. C., preferably to a temperature close to 550.degree. C. and kept in the temperature range mentioned for 3 to 60 hours, preferably for about 24 hours.
  • the nitrating agent can be supplied in the form of a gas, preferably consisting of NH 3 and N 2 parts, optionally also having H 2 , a liquid or a plasma.
  • nitrogen atoms are ionized in an evacuated chamber, after which they are attracted to the oppositely polarized surface 22 of the ring travelers 10 and combine with the iron to form iron nitride
  • Ring travelers 10 treated according to the invention have the following Treatment preferably a black, blue, yellow or white glossy surface 22a.
  • the active medium preferably has Sulfur and / or carbon parts. This can reduce the coefficient of friction on the one hand and at the same time influences the formation of the nitrided zones become.
  • core 20 of the ring traveler 10 a possibly multi-part nitrided edge layer formed, which is based on FIGS to 5 is explained in more detail.
  • Fig. 2 shows a section through the core 20 of a untreated ring traveler 10. It can be seen that Basic material unchanged over the entire core cross-section 21 is present.
  • Fig. 3 shows a section through the core 20a treated ring traveler 10, which is a thin, made of nitrided Base material has existing surface layer, the is referred to as connection layer 23, in which one extensive diffusion saturation has occurred.
  • Fig. 4 shows a section through the core 20b intensively treated ring traveler 10, which is a connection layer 23 and another one made of nitrided Base material existing layer, which as Diffusion layer 24 is referred to.
  • Diffusion layer 24 is nitrogen-enriched mixed crystals and contain excreted nitrides.
  • Fig. 5 shows a section through the core 20c treated ring traveler 10 of only one diffusion layer 24 and have no connection layer 23.
  • layer structure is made according to the requirement profile for ring traveler 10.
  • Running speeds will preferably be a hard tie layer intended.
  • ring travelers 10 who are subjected to relatively high forces under Avoiding a connection layer, preferably only a tougher, yet relatively hard diffusion layer 24 chosen.
  • the connecting layer preferably has a thickness of 0.1 ⁇ m - 30 ⁇ m and the diffusion layer has a thickness of 1 ⁇ m - 2,000 ⁇ m. This is particularly advantageous Use a tie layer with a thickness of 8 ⁇ m - 12 ⁇ m and a diffusion layer with a thickness of 100 ⁇ m - 200 ⁇ m. By choosing a small thickness or completely avoiding the connection layer Material breaks can be prevented, which have been used so far made this technology impossible in this area to have.
  • the layer thicknesses resulting from the nitriding treatment are strong in steel composition and Surface condition of the untreated ring travelers 10 dependent. Basically, when there is a high nitrogen supply and high temperatures a large connection layer and with low nitrogen supply and low temperatures achieved a thin connection layer.
  • the layer thicknesses or the diffusion depths depend on the Treatment duration.
  • Fine, light ring travelers 10 are also during a shorter duration treated as coarse, heavy ring travelers 10th
  • the coefficient of friction can be reduced. simultaneously can the thickness of the tie layer and the Diffusion layer can be tailored as needed.
  • connection layer When choosing small thicknesses of the connection layer there are only slight changes in the roughness of the Core surface 22a, so that a subsequent polishing the treads can be avoided. Furthermore, a Embrittlement of the core material avoided.
  • Ring traveler 10 which has a high chemical stress are preferably post-oxidized.
  • the nitriding treatment is preferably carried out for the entire ring traveler 10, although it is also possible, only the mechanically and / or chemically stressed To provide areas with a nitrided edge zone.
