Definitions

  • the invention has for its object to provide a false twisting device which, in addition to the switchability between and S to Z twist, can be functionally attached to a texturing machine in practically any orientation, in particular also offers the possibility of shifting forces caused by a the inclined orientation of the device on the machine deviating from the normal working position can be caused to compensate or compensate.
  • three spindles 18, 20, 22, shown broken and each equipped with a plurality of friction disks 16, are rotatably arranged, the bearings of which satisfy modern high-speed texturing processes.
  • the bearings (not shown) are so far apart in a fastening 12a at the tips of an arrangement in the form of an isosceles triangle that partial regions of the friction disks 16 pointing into the interior of the triangle overlap. This overlap area is used in a known manner for twisting the threads of a thread.
  • the lower part 14 of the device 10 consists of a holder 26, which is used to attach the device 10 to the frame of the texturing machine, not shown. From the upper end of the holder 26, rod-shaped arms 28 protrude at right angles, only one of which is visible and which carry a carriage 30 connected to the upper part 12 of the device 10.
  • An adjustable support arm 32 is provided on the end of the holder 26 opposite the arms 28, and a pressure roller 34 is provided on the free end thereof is mounted, the outer surface of which is parallel to the outer surface of the whorl 24 when the upper part 12 is attached.
  • the pressure roller 34 can be switched from the position shown in FIGS. 1 and 3 to the position shown in FIGS. 2 and 4 when the whorl 24 is repositioned accordingly, so that it lies either on one or the other side of a drive belt 36.
  • an additional one-sided loading of the compression spring 46 can counteract a shift in force that occurs as a result.
  • the upper plate 48 of the slide 30 is adjusted to the right against the lower 50, so that the distance between the shoulder 66, which is fixedly connected to the spring 46, and the bolt 40a is reduced, and thus the compression of the Spring 46 would be increased in this area. Accordingly, the spring 46 is relieved in the area between the lugs 66 and 52. Subsequent rotation of the sleeve 58, while the spring 46 is tensioned, causes the slide 30 to be shifted to the right on the bracket 28 over its entire length.
