Definitions

  • An improved yarn spinning device having a spindle for winding up yarn, a traveler for receiving and redirecting the yarn, and a metal ring for guiding the traveler as it is moved about the spindle by the action of the yarn being wound on the spindle, the ring having a bearing surface for contacting the traveler.
  • the improvement includes a bearing surface having a multiplicity of smooth-surfaced indentations for accumulating the natural elements that separate from the yarn during processing and adapting those elements to act as lubricants between the traveler and ring, those elements including Waxes and finishes used in processing the yarn and fibers of the yarn alone and in combination with the waxes and finishes.
  • This invention relates to yarn spinning and twisting devices, and more particularly to an improved ring for guiding the traveler in such devices.
  • the oil film on the ring is transferred to the traveler and creates a sticky surface which facilitates the accumulation of lint on the traveler.
  • This accumulation increases the drag of the traveler, resulting in heavier yarn tension and an increased wear rate of the traveler.
  • the oil-fouled lint is also difficult to remove by conventional traveler cleaning means. Attempts to employ a soft or velvety surface applied to the bearing surface of the ring have proved unsuccessful for such a surface, while it does retain certain particles of the yarn, being on the metal ring wears quickly and its lubricating power is lost.
  • an improved yarn spinning device having a spindle for winding up yarn, a traveler for receiving and redirecting the yarn, and a metal ring for guiding the traveler as it is moved about the spindle by the action of the yarn being wound on the spindle, the ring having bearing surface for contacting the traveler.
  • the improvement includes a bearing surface having a multiplicity of smooth-surfaced indentations for accumulating the natural elements that separate from the yarn during processing and adapting those elements to act as lubricants between the traveler and ring, those elements including waxes and finishes used in processing the yarn and fibers of the yarn alone and in combiantion with the waxes and finishes.
  • FIG. 1 is a plan view of a spinning device using a spindle, traveler and ring in accordance with this invention
  • FIG. 2 is a sectional view of the ring and its support taken along line 2-2 of FIG. 1;
  • FIG. 3 is an enlarged view of a section of the ring taken along line 33 of FIG. 2, showing the bearing surface of the ring;
  • FIG. 4 is an enlarged sectional view taken along line 44 of FIG. 3 with the compressive layer somewhat exaggerated;
  • FIG. 5 is a magnified sectional view of a portion of the bearing surface of the ring.
  • FIG. 1 a spinning device 10 for winding yarn 12 on spindle 14 by means of a hardened steel traveler 16.
  • Spindle 14 is rotated about its central, vertical axis by a suitable source of power not here shown.
  • Yarn 12 is fed to traveler 16 from the output of a yarn processing machine, not shown.
  • yarn 12 is wound on it in layers 18, FIG. 2, and the action of yarn 12 as it is wound moves traveler 16 about metal ring 20.
  • Ring 20 has a horizontal flange 22 and a vertical Web 24; web 24 abuts shoulder 26 of holder 28 when the ring is mounted therein. And ledge 30 of holder 28 supports base 32 of web 24.
  • the horns 34 of traveler 16 retain the traveler on ring 20 by guiding on bearing surface 38 on the lower and edge portions of flange 22.
  • Bearing surface 38 has a compressive layer 42 extending from the surface to a depth of approximately 0.002- 0.008 inch, FIGS. 3 and 4.
  • Compressive layer 42 is formed by shot peening the ring with steel balls having a hardness value of approximately 60 on the Rockwell C scale (Re), the shot peening compressively stressing the ring and densifying its crystalline structure in the layer 42 extending inwardly from surface 38, which results in the layer having a compressive residual stress of approximately 148,000 pounds per square inch and a hardness of approximately 58 Rc.
  • the shot peening of bearing surface 38 provides, in addition to the high hardness compressive layer, a surmild mechanical treatment may, for instance, consist of striking, rubbing, brushing, or vibrating. Such treatment during the electrical treatment will not only fold out but also spread the material out.
  • the sheet material is in a spread-out condition wherein the individual fibrils, making up the material, are parallel to the longitudinally axis of the sheet material.
  • this is a desirable configuration.
  • the yarn used in the manufacture therein should not be lean and smooth but rather should have a high percentage of loose-fibrils along the surface of the web or sheet as the case may be.
  • it is essential to use a bulky yarn which is not produced under the process described in the above-identified patent.
  • My invention resides in forming a pile fabric from this polymeric sheet material as it emerges from the foldingout step.
  • a plurality of rollers 54 are shaped to form a crown 56 at their centers.
  • the fibrils in the central portion of film 10 passing over the crown 56 will break while those in the edge portion of the film passing over the edge of the roller will not.
  • This action of crowned rollers 54 causes the fibrils in the center portion of sheet 10 to break.
  • This web is particularly useful in making yarn and as such it is twisted by conventional yarn twisting means as it is wound onto a spool 58.
  • rollers 13, 54 (only one roller is shown; however, it would be within the skill of the art to connect a plurality of crowned rollers into the mechanism) and 29 are connected to a suitable driving mechanism 30.
  • This mechanism comprises an endless belt or chain 32 which passes over a pulley or sprocket 34 which is fixed to roller 54, then over a sprocket 36 which is fixed to roller 13, then over a sprocket 38 which is fixed to roller 29, then over an idler sprocket 40, then over a drive sprocket 42, which is driven by any suitable power source such as electric motor 44, and finally back over sprocket 34.
  • the rollers 12, 13, 54, 28, and 29 are rotated in the directions shown by the arrows.
  • roller 22 is provided with a plurality of grooves 24 and a plurality of needles 26- or other similar sharp, pointed implements, which project radially from the center of the grooves 24. These needles may be secured in the grooves 24 in any suitable manner.
  • portions of it are channelled into the grooves 24 and become impaled upon the needles which penetrate through the sheet material and cause a portion of the individual fibrils to be severed.
  • the degree of breakage would be determined by the number of grooves in the roller and the number of pins in the grooves; however, no more than one-half of the fibers passing over the roller should be broken in order to retain sufiicient web strength.
  • rollers 28 and 29 which are also rotatably mounted in the frame plates 14 and 16. These rollers feed the bulky sheet material to a suitable take-up mandrel (not shown).
  • FIGURE 5 illustrates another embodiment of my invention.
  • a roller 46 contains a plurality of grooves 48 around the perimeter thereof. These grooves are cut at an angle of 45 to the horizontal axis 50 of the roller 46.
  • This roller 46 is attached to frames 14 and 16 in place of roller 22.
  • a plurality of knife blades 52 are positioned around the circumference of roller 53 rotatably mounted between the vertical frames 14 and 16 a predetermined distance from roller 46.
  • the sheet 10 is passed between the roller and the blade.
  • the blade 52 is rotated in close enough proximity to the roller 46 so that portions of the film 10 pass over the crown of the grooves 48 and are cut by the rotating blades 52.
  • a 60-inch wide fibrillated web of 0.8 mil polyethylene, having a density of 0.95 gram/cc. and a melt index of 0.3 (ASTM D 123 8-5DT, Condition E), is threaded through the machine described in FIGURE 2.
  • a chopper roller 53 is provided with 12 tempered spring steel blades 52 around its circumference. The blades 52 coact with a 12-inch diameter grooved roller 46, made of mild steel and coated to a thickness of 60 mils with durometer rubber.
  • Each groove 48 in roller 46 defines an ellipse in a plane making a 45 angle with the roller axis.
  • These grooves are Aa-inch wide, Aa-inch deep, and spaced so that their centers are fli-inch apart, and having all their edges and corners chamfered and rounded on a -inch radius.
  • Bulk film is fed to roller 12 at the rate of 20 feet per minute while the machine is being adjusted to insure clean, uniform cuts. After adjustment, the rate is increased to feet per minute and about 2000 feet of the material is fed through the machine.
  • Air filters 2 /2 feet square are produced from some of this material by laminating 21 layers of this bulked film together, each layer being laid at right angles to the adjacent layers 21 and being stitched together in both directions across the film at 6-inch intervals with cotton string and subsequently edged with an aluminum channel having a As-inch flange.
  • Example 11 The rollers 46 and 53 are replaced with a 12-inch diameter pin-studded roller 22 similar to that shown in FIGURE 4.
  • the grooves 24 are /2-inch center-to-center with a sharp 60 included angle peak between the grooves.
  • equally spaced cylindrical pins 26 are positioned wherein each pin is 7 -inch in diameter and has a flat, sharp edged top portion located -inch below the peaks.
  • Web material similar to that used in Example I is threaded through the machine and the machine is started and run at an initial rate of about 15 feet per minute output while adjustments of the film tension over the pinstudded roller 22 are made. After adjustment, the rate is increased to 150 feet per minute to produce approximately
