Definitions

  • the invention relates to a method for texturing threads, which are first fed to a first delivery mechanism, then textured and provided with a false twist and finally fed to a second delivery mechanism. Furthermore, the invention extends to a texturing device with a texturing nozzle surrounded by a housing, around which an annular space is provided. This is connected on the one hand via a line to a compressed air source and on the other hand via radial bores to the interior of the texturing nozzle.
  • the false twister following the threads of the texturing nozzle is an aggregate sensitive to dust and fiber deposits, especially if it consists essentially of a twist pin rotatably mounted about its axis.
  • This swirl pin which is wrapped by the thread by 180 °, is forced onto a circumferential speed that essentially corresponds to the thread running speed, which leads to extraordinarily high speeds with a pin diameter of only a few millimeters. Even slight contamination of this unit causes considerable friction losses. Relatively frequent business interruptions for cleaning, maintenance and repair purposes are therefore inevitable.
  • the invention is based on the object of proposing an improved and, in particular, trouble-free working method for texturing threads, in particular of glass fibers, the filaments forming the thread also being textured in the optimally twisted state.
  • the swirl process and the texturing process are combined into one process step, so that not only the thread is spared covering the shortest distance between a texturing nozzle and a false twister, but also separate units for texturing and the false twist task are dispensed with.
  • the combined texturing and swirling has the particular advantage that the high-speed air currents required for texturing are also effective in the false twist area, thereby preventing dust and fiber deposits and the formation of other contaminants.
  • a texturing device which is equipped with a texturing nozzle surrounded by a housing, around which an annular space is provided, which on the one hand has a line with a compressed air source and, on the other hand, has holes which are essentially radial and inclined to the direction of the thread is connected to the interior of the texturing nozzle.
  • the inner wall of the texturing nozzle is provided with spirally extending grooves over at least part of its axial extent.
  • the grooves which preferably extend continuously with a large slope over at least a certain distance in front of and behind the mouth region of the essentially radial bores which are inclined to the direction of the thread, impart both the thread and the air jets, which also preferably flow tangentially into the interior of the texturing nozzle , a spin that twists the thread intensively without taking any further precautions.
  • the filaments pressed against the inner wall of the texturing nozzle in the textured state of the thread are effectively carried along by the rotation of the nozzle, whereby the thread also twists intensely.
  • a further embodiment of the invention provides for the texturing nozzle to be provided with spirally running grooves as well as to be rotatably supported and driven in the housing .
  • the texturing nozzle is provided with a conically narrowing entry area, a cylindrical center piece and an exit area that widens conically or in an arc.
  • an embodiment of the invention finally provides that the texturing nozzle is provided with a cross pin which is arranged within the widening outlet region and penetrates the interior of the texturing nozzle .
  • the thread can only pass the cross pin on one side, it is not just for the Thread passage available exit area of the texturing nozzle is reduced to less than half, but the thread is also displaced in the area of the cross pin from the area of the nozzle center axis and is subjected to a centrifugal force due to the eccentric position thus forced, as a result of which the thread is pressed intensively against the inner wall of the nozzle, which is a powerful swirl still favors.
  • a thread 3 composed of filaments runs through a texturing nozzle, generally designated 1 and surrounded by a housing (not shown), in the direction of an arrow 2.
  • This thread runs into the texturing nozzle 1 via a conically narrowed inlet area 4, and an essentially cylindrical one passes Middle piece 5 and occurs via an arcuately enlarged outlet area 6 in a textured and twisted state.
  • the texturing nozzle 1 is pressurized with compressed air via bores 7 which are inclined at acute angles to the running direction of the thread 3, the bores 7 being arranged in a uniform distribution around the circumference of the texturing nozzle 1 and opening tangentially in the essentially cylindrical center piece 5. This is provided over its axial extent with spirally extending grooves 8 which extend to the outlet cross section of the texturing nozzle 1.
  • adjacent grooves 8 are laterally separated from each other by a web 9, which has an approximately semicircular cross section, so that sharp edges that could injure the thread 3 passing through are avoided.
  • the swirl air introduced and with it the thread receives an intense effect around its longitudinal axis and is thereby twisted at the same time as its texturing.
  • the texturing and twisting effect can also be achieved in that the texturing nozzle 1 'is rotatably arranged in a housing 11 via ball bearings 10 and is rotated about its axis via a drive wheel 12.
  • a thread runs in the direction of an arrow 2 via a conically narrowed inlet area 4 'into the texturing nozzle 1', passes through a cylindrical middle piece 5 'and exits via a conically enlarged outlet area 6' in a likewise textured and twisted state.
  • the housing 11 encloses an annular space 13 which is delimited on both end faces by sealing disks 14 which are approximately U-shaped in cross section, an inner edge of the sealing disks 14 being provided with an elastic sealing ring 15.
  • the annular space 13 is connected via a radial nozzle 16 to a compressed air source, not shown.
  • a compressed air source not shown.
  • bores 7' are in turn arranged at an acute angle to the central axis of the texturing nozzle 1 ', via which the compressed air is applied to the center piece 5' from the annular space 13.
  • the thread is puffed up in the middle piece 5 'by the compressed air, pressed against its inner wall and thus the rotational movement of the texturing nozzle 1' is transferred to the thread.
  • a cross pin 17 penetrates the outlet area 6 'of the texturing nozzle 1' and forces the thread to eccentrically shift, which thereby increases one Centrifugal force is subjected. Through this, the thread is also pressed against the inner wall in the widening outlet area 6 ', so that the rotational movement is intensively continued.
