Definitions

  • This invention relates to textile yarn twisting'and more particularly to a double twister.
  • the driven rotating part of the known double twister usually comprises a so-called take-up disk.
  • This disk sometimes includes or has attached thereto a so-called buffer body which rotates at the same speed as the disk.
  • the yarn passes in contact with this buffer body after leaving the hollow spindle and before moving upward.
  • the extent to which the yarn contacts the buffer body depends on a number of factors such as the pre-tension, thickness of the yarn, and spindle speed.
  • a great disadvantage of known double twisters is that the size of the yarn package placed on the double twister is-limitedby the size of the disk. Since the balloon formed by the yarn should not touch the package, the diameter of the yarn package generally cannot exceed and is usually smaller than the diameter of the rotor.
  • Another disadvantage of known double twisters is the considerable power consumption of the rotating parts at higher R. P. M. The power consumption, of course, is greatly influenced by the size of the moving parts.
  • Another object is to provide a double twisterjwhich will operate with smaller amounts of electric power.
  • a still further object of the invention is to provide a double twister of improved utility that may be readily adjusted to compensate for variations in process conditions.
  • Figure l is a side elevational view of a double twister spindle embodying one form of the present invention.
  • Figure 2 is a perspective view showing in more detail the thread guiding member of Figure 1;
  • Figure 3 is a plan View of a double twister spindle constructed according to the present invention and equipped with a modified form of thread guide.
  • a double twister is provided with a freely rotatable thread guiding member concentrically mounted around the driven spindle of the double twister.
  • the double twister of the present invention possesses the advantages that no take-up disk is present and the driven rotor consists principally of a buffer body from which the yarn emerges.
  • the dimensions, and particularly the diameter, of the buffer body are independent of the size of the yarn package to be twisted and may be kept as small as possible.
  • the freely rotatable thread guiding member gf the "ice present invention is preferably constructed in the form of a yer.
  • This flyer may be made in various sizes, the important consideration being that as little resistance as possible is experienced during its rotation. Very good results are obtained if the flyer is constructed from a thin metal wire such as steel Wire, which surrounds the double twister spindle in the form of an eyelet.
  • the end ⁇ of the metal wire is provided with any suitable thread guide, such as a thread eyelet.
  • the numeral 10 designates a yarn supply package being supported on stator member 11.
  • Supply package 10 is concentrically arranged around a tubular member 13. Any well-known type of pre-tensioning member (not shown) may be present in tubular member 13.
  • Tubular member 13 is in axial alignment with driven spindle 14 and stator member 11 is freely rotatably supported in known manner by said spindle.
  • the upper part of spindle 14 is provided with an axial opening which communicates with radial opening 15 in a flange-like buffer body 16 which is attached to the spindle below and in spaced relation to stator member 11.
  • the upper part of spindle 14, that is the part which lies above body 16, is of reduced diameter.
  • flyer member 17 Disposed between stator 11 and buffer body 16 is a flyer member 17, concentrically mounted to rotate freely around driven spindle 14.
  • a thread guide member 18 is attached to each extremity of flyer 17. As seen in Figure 2, thread guide 18 may comprise-a detachable fork.
  • Flyer 17 is attached to a hub or ring-like member 9 which surrounds the spindle, as shown in Figure 3.
  • the yarn 12 is withdrawn from supply package 10 and passes via tubular member 13 through the axial opening in spindle 14 and out through the radial opening 15 in buffer body 16.
  • the yarn 12 remains in contact with the buffer body 16 for a certain time, depending on such factors as the pre-tension and the speed, and then passes through the thread guide 18 and balloons upward to a winding device (not shown) via thread guide 19.
  • the flyer 17 adjusts itself in such a waythat the yarn first lies in the form of an arc against buffer body 16 and then passes to the balloon through the thread guiding member ⁇ 18 of flyer 17. If sudden changes occur in the tension during operation, injurious effects are prevented by a change in the position of the flyer with respect to the point where the yarn leaves the buffer body. Such changes also tend to be compensated for by an adjustment of the angle of contact of the yarn around the thread guiding member. However, the speed of rotation of the thread guiding member always remains equal to that of the rotating part of the twisting device.
  • Double flyer 20 consists of two metal wires, the ends of which are provided with eye-shaped thread guides 21 connected to a ring-shaped hub member 22 concentrically mounted for free rotation around driven hollow spindle 23. Double flyer 20 is mounted above buffer body 24 as in the arrangement described above.
  • the buffer body can have any shape, so long as its diameter is less than that of the flyer. lt is even possible to use the rotating spindle as a buffer body if its diameter is suitable for this purpose.
  • the yer need not be a double flyer as indicated in the drawings) It is possible to use a"single lyerprovided with a counter-weight.
  • the power consumption of the device' made according to the invention was 9 watts ⁇ at 6,000 R. P. ML and'17 Watts at 9,'000NR.A P. M.
  • the power consumption of the 'double twister of conventional structure was 37. watts at 6,000 R. P. M. and 98 watts at 9,000 R. P.y M.Y
  • a considerable saving in electrical power 4 is attainedrby the present invention.
  • An equally important advantage of the' double twister ofthe present invention is the manner in whichit may bev easily adaptedY to various processing circumstances by. merely exchanging the yeij.
