Definitions

  • the invention relates to a machine for twisting yarn and a belt drive mechanism in the machines for driving a plurality of false twist spindle units individually rotatable about their own axes to twist lengths of yarn characterised in that the spindle units are driven from the faces of one or other of parallel runs of at least two driving belts driven by a common driving member.
  • This invention relates to transmission means for rotating a plurality of false-twist spindles in a yarn processing machine wherein the yarns are continuously given a twisting movement while they are simultaneously being drawn through the spindles in apparatus for processing yarns, for example in false twist-yarn-crimping machines.
  • the driving belts or driving bands of the transmission means for rotating these spindles are of the order of 80 feet in length, continuous or flexibly jointed, smooth in surface and of thin section and are usually driven directly from a pulley mounted on an electric motor.
  • the driving belt or band usually extends around the entire yarn twist machine and is capable of turning about 2300 twist spindles simultaneously at high speeds, the belt or band taking the total torque or horsepower directly from the motor pulley.
  • the number of spindles which can be applied to the belt per unit length is limited relative to the width of the false twist spindle unit or assembly and in relation to the length of the belt employed and the power it is capable of transmitting.
  • a yarn processing machine having a mechanism for driving a plurality of false twist spindle units characterised in that said units are driven from one or other of the faces of one or other of the parallel runs of at least one driving belt driven from a common driving member.
  • FIG. 1 shows a conventional false twist spindle unit driving mechanism
  • FIG. 2 shows one embodiment of a false twist spindle unit driving mechanism according to the present invention
  • FIG. 3 shows another false twist spindle unit driving mechanism according to the present invention
  • FIG. 4 is a plan view of the mechanism shown in FIG. 3'.
  • FIGS. 5, 6 and 7 illustrate various different false twist spindle driving arrangements.
  • FIG. 1 shows a known false twist spindle unit driving mechanism comprising, on an electric motor shaft, a pulley 1 which drives an endless belt 2 which is guided and supported on idle pulleys 3, 4.
  • the belt 2 drivingly engages on a series of false twist spindle units 5.
  • the motor rating is of the order to 15-20 HP. and the total load of the spindle units is sustained by the single belt.
  • a driving mechanism which is shown in FIG. 2 is characterised by the provision of two driving belts 16, 20 guided and supported by idle pulleys 30, 40, 11, 12, 13 and 14 and driven by pulleys 15 and 6.
  • the latter pulleys are fixed to the same shafts as pulleys 8 and 9 respectively which are driven by an electric motor drive by means of a belt 7 which also passes around an idler pulley 19.
  • the false twist spindle units 17, 18 are driven by contact with one face or the other of one or other run of each belt and it will be appreciated that the total load is sustained by the two belts 16, 20 and two belt driving pulleys 8, 9.
  • FIGS. 3 and 4 illustrate a more elaborate embodiment of the invention wherein, as with FIG. 2, two belts 21, 22, together drive all the false twist spindle units 27, 28.
  • the belts 21, 22 are guided by pulleys 70 and respectively and driven from pulleys 60 and 50 respectively.
  • Multi-grooved pulleys 35, 45 are fixed to the same shafts as the pulleys 50, 60 respectively and are driven through V belts 25 from a drive pulley 26 on the driving shaft of an electric motor 23.
  • FIG. 5 shows a false twist spindle 51 engaged by two rollers 31, 61 driven from belt runs 32, 62 respectively.
  • FIG. 6 shows how two false twist spindles 52, 68 can be driven by two rollers 53, 63 respectively with an intermediate roller 64 between them.
  • FIG. 7 shows how a single false twist spindle 54 can be driven by two rollers 34, 44 which are in contact with two opposed belt runs and which have an intermediate restraining roller 66 between them.
  • a mechanism to rotate the spindle units includes a belt drive having parallel belt runs driving the false-twist spindles, the improvement comprising at least two spindle-driving belts, an individual pulley driving each of said spindle-driving belts, and a common motor drive driving the individual pulleys simultaneously by means of a common belt-drive.
  • a yarn processing machine as in claim 1 which further includes at least one idle pulley associated with each of said spindle-driving belts and assisting said mechanism in power transmission from said common motor drive.
  • a yarn processing machine as in claim 4 which 68, 25 6/1961 France 5777.45
