Definitions

  • This invention relates to apparatus for use in withdrawing yarn from yarn packages such as bobbins, cones and the like.
  • the present invention provides an improved form of device for preventing the formation of snarls which can be used with holders projecting in any direction including the vertical.
  • a pleated material such as a pleated fabric which surrounds the yarn package during the yarn withdrawal.
  • the pleated material may be in a cylindrical or conical form, the actual shape used being preferably adapted to the shape of the package.
  • An essential feature of the pleated material is that its inner edges provide a number of line contacts with the package, the pressure of such contacts being sufficient to prevent the yarn overrunning while interfering as little as possible with the yarn withdrawal.
  • the pleated material used in this invention should be made sufiiciently elastic, for example by a suitable selection of such factors as construction of the fabric, the size and strength of the pleats and dimensions of the material that the pleated material maintains line contacts with the package at all times during the withdrawal of the yarns. It is not essential for the line contacts between the pleats and the package to extend continuously over the length of the package so long as sufiicient contact is provided to prevent the yarn overrunning.
  • the pressure should, of course, be adapted to the yarn being processed so that the yarn is not damaged by the pressure.
  • the pleated device used in this invention is preferably made of fabric but other materials such as paper or a plastic material may be used.
  • a suitable fabric may be made from thermoplastic yarns such as cellulose triacetate yarns, nylon yarns or polyethylene terephthalate yarns so that the pleats may be inserted using standard pleating techniques for such fabrics.
  • FIGURE 1 is a plan view of a surround or sleeve of a pleated fabric surrounding a vertical yarn package in accordance with the invention.
  • FIGURE 2 is a perspective view of a modified surround or sleeve, the sleeve being made conical.
  • the fabric shown in the drawings is provided with a number of pleats 1 giving a series of line contacts 2 ICC . 2 with a yarn package 3 on a tube 4, the whole assembly being fitted over a carrier 5.
  • the sleeve may be pleated throughout its entire length from top 6 to bottom 7. Examples of suitable constructions v of fabric as illustrated for use on crimpe'd nylon (1 lb. to 4 oz. packages) are as follows:
  • Example 2 Material-Triacetate ninon fabric, warp and weft both 75 denier 19 filament yarn, 86 ends per inch, 72 picks per inch.
  • Example 3 For a larger package, for example a 4 lb. cone, the fabric construction given above in Example 3 may be used but modified to produce a fabric device having 18 pleats each 6 /2 inches long and 1.8 to 2.3 cm. deep. With such a device it may be necessary when most of the yarn has been withdrawn and the package diameter approaches the diameter of the cone itself, to replace the device by a smaller one constructed for instance as in Examples -1, 2 and 3.
  • the pleated material used according to this invention can be used with horizontal yarn carriers, vertical yarn carriers and carriers at any angle between the two.
  • the pleats are free to expand, as shown in FIGURES 1 and 2 when supported by a yarn package, and to collapse flat when unsupported.
  • the pleated fabric collapses normally to a flat structure which withstands readily the normal hazards under working conditions; it is easily stored and by virtue of its elasticity can he slipped over the yarn package by hand very readily as required.
  • the pleated material When used vertically, it should stand on a smooth surface so that inward movement of the material during unwinding is not impeded.
  • a yarn control device for preventing crimp in lively twisted yarn consisting of a sleeve of material having pleats surrounding said yarn package, said pleats being free to expand or to collapse, and the yarn package comprising a support for said sleeve, the relative size of the yarn package and the sleeve being such that only the inner edges of said pleats contact the outer surface 8.
  • a yarn control device according to claim 2 wherein of the yarn package, whereby the pressure of said pleats the sleeve upon removal from the package collapses prevents the yarn overrunning while allowing Withdrawal normally to a fiat structure thereby withstanding normal of the yarn to proceed unimpeded. hazards under Working conditions.
