Definitions
- the invention relates to a textile 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 twist 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 several movable thread guides which change the pitch of the helical cooling section on the circumference of the cooling tube.
- the cooling path is the thread path that occurs on the circumference of the cooling tube.
- This object is' according to the invention in that a yarn lifter is disposed between the inlet yarn guide and the outlet yarn guide, is guided through which the thread within the cooling zone over a partial length without contacting the circumference of the cooling tube. No intensive cooling of the thread takes place on the section of the cooling section in which the thread is lifted from the surface of the cooling tube.
- the degree of cooling within the cooling section can thus advantageously be set.
- a particular advantage of the invention is that the minimum wraps on the cooling tube required to reduce swirl vibrations are retained. Although the thread piece guided within the cooling section is lengthened by lifting 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, the holder holding the thread guide at a distance from the circumference of the cooling tube. This enables the thread to be lifted from the surface of the cooling tube in a localized manner.
- a particularly simple and very effective variant is given in that the holder is annular and on the cooling tube is attached.
- 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 guide edge for guiding the thread, is characterized by an even greater flexibility in the thread guide.
- the ring segment which is arranged on the circumference of the cooling tube, can have a shape such that the thread spacing formed between the leading edge and the surface of the cooling tube is unequal in the circumferential direction of the cooling tube. 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, by increasing the distance between the leading edge and the surface of the cooling tube, an additional intensive wrap friction can be generated on the thread, which advantageously leads to the reduction of the twist 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 thread brake can advantageously be formed by a brake pin which is arranged upstream of the thread lifter in the thread run so that the thread at least partially wraps around the brake pin before it enters the thread lifter.
- the emia thread guide and the outlet thread guide or only one of the thread guides can be designed to be adjustable.

- a processing point is a schematic. shown texturing machine according to the invention.
- the texturing machine has a large number of processing points, the processing units of the processing points being held in one or more machine frames.
- a processing point contains at least a first delivery mechanism 5, a heating device 6, a cooling device 7, a false twist unit 15, a second delivery mechanism 14 and a winding device 16, the processing units being arranged one behind the other to form a thread path.
- a thread 1 is drawn from a supply spool 2 by the first delivery mechanism 5.
- the supply spool 2 is attached to 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 to the false twist unit 15.
- a false twist is generated in the thread 1 by the false twist unit 15, which runs back within the false twist zone in the thread.
- the false twist unit 15 can have, for example, a plurality of overlapping friction disks which generate a false twist on the thread.
- the false twist runs back in the thread within the false twist zone and is heated in the heating device 6 and then fixed in the cooling device 7.
- the thread is drawn off from the false twist unit 15 by the second delivery mechanism 14 and fed to the winding device 16. In the winding device 16, the thread 1 is wound into a bobbin 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 pipe 8 has an inlet thread guide 18 at one end, which guides the thread 1 to the cooling pipe 8 Mn, and an outlet thread guide 19 at the opposite end.
- the end of the cooling tube 8 in the region of the inlet thread guide 18 is referred to here as the leading end 20 and the opposite end of the cooling tube 8 as the ending end 21.
- the coolant is supplied via the run-up end 20, which is connected to the cooling source 9 through the line 10.
- the wall of the cooling tube 8 is cooled by the coolant.
- 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 attached to the circumference of the cooling tube 8.
- the ring segment 12 has an outer guide edge 10 which extends at a distance from the surface of the cooling tube 8 essentially in the radial direction.
- FIG. 2 schematically shows a view of the cooling device of the texturing machine from FIG. 1.
- the inlet thread guide 18 and the outlet thread guide 19 are designed to be pivotable, so that the degree of wrap and thus the helical cooling path on the circumference of the cooling tube 8 can be adjusted.
- Part length is the distance between the leading edge 13 and
- the ring segment 12 can be adjusted in the axial direction as well as in the radial direction on the circumference of the cooling tube 8.
- the ring segment 12 has an elliptical or step-like shape, as shown in FIG. 3.
- the shape of the ring segment 12 is arbitrary, so that any thread spacing can be realized.
- the ring segment 12 could have an area in which the thread maintains contact with the cooling tube 8.
- the ring segment 12 is fixed to the circumference of the cooling tube 8 by a fixing means 29. By loosening the fixing means 29, the ring segment 12 can be moved into any position on the circumference of the cooling tube 8.
- FIG. 4 shows a further exemplary embodiment of a cooling device 7, as would be used, for example, in the texturing machine shown in FIG. 1.
- a thread lifter 11 is assigned to the cooling tube 8 between the inlet thread guide 18 and the drain thread guide 19.
- the thread lifter 11 is formed by a holder 22 and a thread guide 23.
- the holder 22 is attached to the side of the cooling tube.
- the thread guide 23 is designed as a pin and protrudes into the thread running plane of the cooling tube 8.
- the thread 1 is guided within the cooling section in the area of the cooling tube 8 via the thread guide 23, so that in a partial area of the cooling section the thread 1 is not in contact with the surface of the cooling tube 8.
- FIG. 5 and 6 show a further exemplary embodiment of a cooling device 7, as would be used, for example, in the texturing machine according to FIG. 1.
- a section of the cooling tube 8 is shown with a thread lifter 11.
