Definitions

  • This invention relates to a paraffin-waxing device for a textile winding machine which transfers the yarn from a package on the feed side to the package under formation.
  • the invention relates to a paraffin-waxing device having a yarn guide pin fixed to the centre of a flange between the support pegs for the paraffin wax disc, said yarn guide pin being positioned axially by spacer elements so that its slot intercepts the advancing yarn in order to deviate it in such a manner as to obtain the correct contact pressure between the yarn and the paraffin wax disc.
  • paraffin wax indicates any type of composition similar to the solid paraffin wax used to lubricate or coat the yarn for the purpose of reducing its coefficient of friction in its sliding along the guide members during the subsequent operating stages, and for the other typical purposes of paraffin-waxing. Essentially, paraffin-waxing improves yarn working and consequently the quality of the finished product.
  • Winding forms part of the fibre working process in the textile industry and part of the winding procedure involves passing the yarn through a device which applies paraffin wax to the yarn.
  • a paraffin wax disc or roller is used, rotated by a belt or geared motor, the yarn sliding along its top front. This allows the paraffin wax to be distributed uniformly over the entire length of the yarn. It also results in uniform consumption of the paraffin wax disc and uniform contact with the yarn.
  • Paraffin-waxing devices are known which operate reliably and provide constant paraffin-waxing of the yarn, so satisfying the essential requirement of a paraffin-waxing device for use in a winding unit.
  • paraffin-waxing the main purpose of paraffin-waxing is to reduce to a minimum the coefficient of friction between the yarn and its contacting members, and in doing this it is necessary in each case to experimentally determine the optimum quantity of paraffin wax to deposit on the yarn, this depending on the type of paraffin wax used and the nature of the yarn.
  • yarn guide lever mechanisms or yarn tensioning eyelets of complicated construction and adjustment are used in known paraffin-waxing devices.
  • Said known means deviate the moving yarn to a greater or lesser extent to cause it to slide over the front surface of the paraffin wax disc at different pressure.
  • the primary factor which directly influences paraffin-waxing is the pressure with which the moving yarn rests on and presses against the paraffin wax disc.
  • the ratio of the quantity of paraffin wax deposited on the yarn to the pressure of the moving yarn against the front surface of the paraffin wax disc is almost linear.
  • the pressure of the moving yarn against the paraffin wax disc is directly related to the deviation to which the yarn path is subjected by yarn guide elements which compel it to envelop about the substantially ring-shaped front surface of the paraffin wax disc.
  • the present invention provides an improvement in the paraffin-­waxing device, and in particular an improvement in those elements or means used for deviating the moving yarn for the purpose of obtaining precise regulation of the quantity of paraffin wax to be deposited on the yarn, which satisfies the following objects: - to allow the yarn pressure on the front surface of the paraffin wax disc to be adjusted to exactly the same value for the entire succession of winding units; - to allow the quantity of paraffin wax which adheres to the yarn to be predetermined according to the technical requirements of the yarn being worked, by simple and rapid adjustments by the service operator which do not depend on his ability or diligence.
  • a paraffin-waxing device for a textile winding machine comprising a disc of solid paraffin wax for depositing a predetermined quantity of paraffin wax on yarn being wound onto a forming package from a feed package, said paraffin wax disc being carried by a shaft on which it is mobile axially by the action of a compression spring which urges it against pegs projecting from a frontal flange on which they are integrally fixed.
  • a yarn guide pin At the centre of said flange between said pegs there is fixed a yarn guide pin the position of which, or its axial projection from the flange, is determined by spacer elements of substantially flat washer form.
  • Said spacer elements are inserted or withdrawn from between said yarn guide pin and said frontal flange to deviate the advancing yarn to a greater or lesser extent in order to obtain the correct contact pressure between the yarn and the paraffin wax disc.
  • the central yarn guide pin cantilever-fixed onto said flange is axially displaceable by means of screw elements.
  • the central yarn guide pin comprises a yarn interception slot of annular shape, said central yarn guide pin being able to rotate freely about itself.
  • 6 is the yarn being wound onto a forming package from a feed package (neither of which is shown), said yarn travelling from the bottom upwards and passing through the paraffin-waxing device; 7 and 14 are fixed yarn guide elements located respectively one below and one above the paraffin-waxing disc.
  • Said guide elements position the yarn at the entry and at the exit of the paraffin-­waxing device; 8 is a shaft of square or polygonal cross-section rotated by the geared motor 16 which by means of said shaft 8 slowly rotates the disc of paraffin wax 2 together with its housing 10; 1 is the central yarn guide pin which by means of its slot intercepts and deviates the yarn which advances through the paraffin-waxing device to cause it to undergo deviation to the extent of obtaining correct contact pressure between the yarn and the paraffin wax disc; 2 is the solid paraffin wax disc or roller housed in its cylindrical housing 10, said paraffin wax disc being urged axially forwards by an elastic element of helical spring type 5.
  • Said slot can be formed laterally or can extend annularly, its depth and width being conveniently suitable for guiding and deviating the various types of yarns being worked.
  • the guide elements for the yarn being worked must have those surfaces in contact with the moving yarn of ceramic or similar material.
  • the paraffin wax disc 2 is positioned such that its frontal surface urged against the pegs 4 deviates the path of the yarn 6, which is taut between the guide elements 7 and 14. It can be understood that said variation causes the yarn to adhere against the paraffin wax under pressure. This adhesion pressure is greater the greater said deviation.
  • This procedure does not enable precise control of the quantity of paraffin wax transferred to the yarn to be obtained to work yarns which are slightly different, or to work the same yarn but with a slightly different amount of paraffin-waxing, for optimisation purposes.
  • the service operator then sets all the paraffin-waxing devices of the successive winding units to the same number of spacers, to ensure that the paraffin-waxing is constant and equal for all said winding units.
