Definitions

  • the invention relates to a texturing machine for false twist texturing of a thread according to the preamble of claim 1.
  • a generic texturing machine is known from EP 0 853 150.
  • a supplied plain yarn is textured by a false twisting process.
  • the false twist generated by a false twist unit is fixed in the thread by a heat treatment and a subsequent cooling.
  • a cooling tube is used, on the surface of which the thread is guided helically.
  • the known texturing machine has a plurality of movable thread guides that change the slope of the helical cooling section on the circumference of the cooling tube. As a cooling section of the adjusts itself on the circumference of the cooling tube yarn path.
  • This object is achieved in that between the inlet yarn guide and the outlet yarn guide a thread lifter is arranged, through which the thread is guided within the cooling section over a partial length without contact on the circumference of the cooling tube. On the section of the cooling section, in which the thread is lifted from the surface of the cooling tube, there is no intensive cooling of the thread.
  • This can advantageously be set the degree of cooling within the cooling section.
  • a particular advantage of the invention is that the minimum Umschlingonne required to reduce swirl vibrations remain on the cooling tube. Although the length of thread guided inside the cooling section is lengthened by lifting off the thread, a weaker cooling is achieved. In particular, threads with fine titers can thus advantageously be textured.
  • the thread lifter can be easily formed by a holder and a thread guide, wherein the holder holds the thread guide at a distance from the circumference of the cooling tube. This allows a localized lifting of the thread from the surface of the cooling tube.
  • the holder for changing the position of the yarn guide relative to the cooling tube in the axial and / or radial direction adjustable form can be solved at any point of the cooling section of the surface of the cooling tube.
  • a particularly simple and very effective embodiment is given by the fact that the holder is annular and on the cooling tube is plugged.
  • the thread guide is formed by a groove on the circumference of the holder.
  • the thread lifter is formed by a ring segment with an outer leading edge for guiding the thread, characterized by an even higher flexibility in the thread guide.
  • the ring segment which is arranged on the circumference of the kublrohres, may have a shape such that the thread spacing formed between the leading edge and the surface of the cooling tube in the circumferential direction of the cooling tube is unequal size. This makes it possible to make the partial length, in which the thread has no contact with the cooling tube, as large as possible. On the other hand, can be produced by increasing the distance between the leading edge and the surface of the cooling tube, an additional intensive wrap friction on the thread, which advantageously leads to the reduction of the swirl vibrations in the thread.
  • the ring segment is advantageously designed to be adjustable on the circumference of the cooling tube in the axial direction and / or radial direction.
  • the yarn brake can advantageously be formed by a brake pin, which is arranged upstream of the thread lifter in the yarn path, so that the thread at least partially surrounds the brake pin before entering the thread lifter.
  • both states can be realized with and without thread brake.
  • the degree of Fadenumschlingung on the brake pin is changeable.
  • the inlet thread guide and the outlet thread guide or only one of the thread guides can be made adjustable.
  • a processing station includes at least a first delivery mechanism 5, a heater 6, a cooling device 7, a false twist unit 15, a second delivery mechanism 14 and a take-up device 16, wherein the processing units are arranged to form a threadline one behind the other.
  • a thread 1 is withdrawn from a document spool 2 by the first delivery mechanism 5.
  • the supply spool 2 is mounted on a mandrel 3 of a gate (not shown here).
  • the first delivery mechanism 5 guides the thread 1 into the so-called false twist zone, which extends as far as the false twist unit 15.
  • the false twist unit 15 By the false twist unit 15, a false twist is generated in the thread 1, which runs back within the false twist zone in the thread.
  • the false twist unit 15 for example, have a plurality of overlapping friction discs, which generate a false twist on the thread.
  • the false twist runs back in the thread and is thereby heated in the heating device 6 and then fixed in the cooling device 7.
  • the second delivery mechanism 14 the thread is subtracted from the false twist unit 15 and fed to the take-up device 16.
  • the thread 1 In the winding device 16, the thread 1 is wound into a coil 17.
  • the cooling device 7 In order to cool the thread 1 within the false twist zone, the cooling device 7 consists of a cooling tube 8, which is connected via a line 10 to a coolant source 9.
  • the cooling tube 8 is an inlet yarn guide 18 at one end, which leads the yarn 1 to the cooling tube 8 and assigned at the opposite end a discharge yarn guide 19.
  • the end of the cooling tube 8 in the region of the inlet thread guide 18 is referred to here as a run-up end 20 and the opposite end of the cooling tube 8 as a drain end 21.
  • the supply of the coolant via the end of run 20, which is connected by the line 10 to the cooling source 9. By the coolant, the wall of the cooling tube 8 is cooled.
  • a thread lifter 11 is arranged on the circumference of the cooling tube 8.
  • the thread lifter 11 is formed by a ring segment 12 that is mounted on the circumference of the cooling tube 8.
  • the ring segment 12 has an outer leading edge 10 which extends at a distance from the surface of the cooling tube 8 substantially in the radial direction.
  • FIG. 2 schematically shows a view of the cooling device of the texturing machine from FIG. 1.
  • the inlet yarn guide 18 and the outlet yarn guide 19 are pivotally formed so that the degree of wrap and thus the helical cooling path on the circumference of the cooling tube 8 are adjustable.
  • the thread 1 is guided over the leading edge 13 of the ring segment 12.
  • the size of the part length is dependent on the distance between the leading edge 13 and the surface of the cooling tube 8 and the Grand of the slope of the helical cooling section on the circumference of the cooling tube 8.
  • the ring segment 12 can be adjusted both in the axial direction and in the radial direction on the circumference of the cooling tube 8.
  • the ring segment 12 has an elliptical or stepped shape, as shown in Fig. 3.
  • the shape of the ring segment 12 is arbitrary, so that each thread spacing can be realized.
  • the ring segment 12 could have a region in which the thread maintains contact with the cooling tube 8.
  • the ring segment 12 is fixed by a fixing means 29 on the circumference of the cooling tube 8. By loosening the fixing means 29, the ring segment 12 can be moved to any position on the circumference of the cooling tube 8.
  • a further embodiment of a cooling device 7 is shown, as they would be used for example in the texturing machine shown in Fig. 1.
  • the cooling tube 8 is assigned a thread lifter 11 between the inlet yarn guide 18 and the drain guide 19.
  • the thread lifter 11 is formed by a holder 22 and a yarn guide 23.
  • the holder 22 is mounted laterally adjacent to the cooling tube.
  • the yarn guide 23 is formed as a pin, and protrudes into the yarn running plane of the cooling tube 8.
  • the thread 1 is guided within the cooling section in the region of the cooling tube 8 via the thread guide 23, so that in a partial region of the cooling section of the thread 1 without contact with the surface of the cooling tube 8.
  • FIG. 5 shows the cooling device in a cross-sectional view
  • FIG. 6 shows the cooling device 7 in a side view.
  • the thread lifter 11 is formed by an annular holder 24 which is attached to the circumference of the cooling tube 8.
  • the annular holder 24 has an outer groove 25, in which groove bottom of the thread 1 is guided. Between the groove bottom of the groove 25 and the surface of the cooling tube 8, a distance is formed, so that the thread 1 is guided in a partial region of the helical cooling section without contact with the cooling tube 8.
  • the yarn guide 11 is preceded by a yarn brake 26 in the yarn path.
  • the yarn brake 26 is in this case formed by a brake pin 27, which has a Carrier 28 is adjustably connected to the annular holder 24.
  • the brake pin 27 is disposed in the yarn path of the groove 25, wherein the position of the brake pin 27 relative to the groove bottom of the groove 25 is variable.
  • the looping of the thread 1 on the brake pin 22 causes additional thread friction, which leads to a further reduction of the swirl vibrations in the thread 1 within the cooling section.
  • yarns with fine titers can advantageously texturize with a low overall wrap of ⁇ 360 °. Even with small angles of wrap within the cooling section on the cooling tube 8, a sufficient reduction of the swirl vibrations can be realized by the yarn brake 11 associated with the thread brake 26 to the inlet to the heater 6.
