Definitions

  • the invention relates to a thread guide according to the preamble of claim 1.
  • Thread guides are mainly used in the textile industry in yarn cleaners.
  • a thread guide is usually arranged before and after the measuring field of the thread cleaner for thread guidance.
  • V-thread guides mostly consist of polished aluminum-ceramic discs with a V-neck (so-called V-thread guides).
  • V-thread guides Common to all of them is the simultaneous limitation of the thread at three different points, which lie in a plane orthogonal to the direction of the thread.
  • This simultaneous narrowing at three planar (in a radial plane) points results in two types of disadvantages: the first disadvantage is that contaminations of the thread (especially thick spots) get stuck in the planar thread narrowing; the second disadvantage is that the thick point causes the thread to jump out of the V-neck of the first thread guide for a short time and the thick point continues outside the measuring field without being noticed.
  • the invention seeks to remedy this.
  • the invention is based on the object. To provide a thread guide in which there is no constriction of the thread run at several points at the same time and which permits the use of a single thread guide per thread cleaner.
  • the invention solves the problem with a thread guide, which has the features of claim 1.
  • a further advantage of the preferred embodiment according to the invention is that, thanks to the three spatially arranged lugs serving as thread limitation, an outlet channel asymmetrical to the running direction of the thread is produced, which can be easily cleaned at any time by means of an air nozzle attached outside the thread path.
  • the thread guide shown in FIGS. 1 and 2 consists essentially of a disk-shaped base body 1 with a front, circular base surface 11 and a rear rectangular base surface 12.
  • the base body 1 is expediently made of aluminum oxide ceramic and its surface parts are polished smooth to reduce the friction that occurs .
  • the disk-shaped base body 1 has a V-shaped cutout 2 on a sector of approximately 60 °, the radii 3, 4 of which serve as the thread inlet and the center 5 of which serves as the thread guide base.
  • the thread guide base 5 is designed as a first nose 6 serving to limit the thread. Its highest radial elevation 13 is shifted by approximately 2 mm with respect to the front base surface 11 in the direction of the rear base surface 12 of the base body 1 in order to facilitate the entry of the thread 10. For the same reason, the inlet ramp 16 of the first nose 6 facing the front base surface 11 has an angle ⁇ of 29.2 ° with respect to the central axis 17 of the base body 1.
  • the right thread inlet 3 - seen in the thread running direction 9 - is designed as a second nose 7 serving to limit the thread.
  • Your highest sectoral survey 14 is as far as possible towards the front Base 11 of the base body 1 shifted.
  • the left thread inlet 4 - seen in the thread running direction 9 - is designed as a third thread 8 serving to limit the thread, the highest sectoral elevation 15 of which is shifted by approximately 2.8 mm relative to the front base surface 11 in the direction of the rear base surface 12 of the base body 1 .
  • the greatest possible axial distance (of at least 1.8 mm) between the two lugs 7 and 8 is thus achieved, which counteracts the simultaneous narrowing of the thread path.
  • the same purpose serves the optimal design of the inlet and outlet ramps 18, 19, 20 of the lugs 7 and 8.
  • the inlet ramp 18 of the second lug 7 facing the front base 11 therefore has an angle ⁇ of 35.5 ° and that of the rear base 12 facing inlet ramp 19 of the third nose 8 an angle ⁇ of 30 ° with respect to the central axis 17 of the base body 1.
  • Due to the fact that the outlet ramp 20 of the second nose 7 facing the rear base surface 12 is arranged at an angle ⁇ of 52 ° with respect to the central axis 17 of the base body 1, an outlet channel 21 (FIG. 4) which runs obliquely to the central axis 17 is created which is now without difficulty can be cleaned by means of a correspondingly arranged in the extension of the outlet channel 21 air nozzle 22.
  • the optimal distance of the radial or sectoral elevations 13, 14 and 15 from the base surface 11 serving as a reference surface depends on the thickness of the yarn used.
