Definitions

  • the invention relates to a texturing machine for stretch texturing of a synthetic thread according to the preamble of claim 1.
  • a generic texturing machine is known for example from EP 0 879 907 AI.
  • Texturing machines of this type are used to texturize one or more threads in order to produce a bulked and crimped yarn from a melt-spun smooth thread, which is suitable for further processing into a knit or woven work.
  • the spun smooth thread is drawn off from a supply spool within a texturing zone, which contains a heating device, a cooling device and a texturing unit, is textured, stretched and, after texturing, is wound into a spool.
  • a wetting device is arranged between the heating device and the cooling device within the texturing zone, through which a cooling fluid is applied to the thread.
  • the thread is passed over a wetted surface with contact, which causes an additional thread friction within the texturing zone.
  • the invention is therefore based on the object of developing a generic texturing machine of the type mentioned in such a way that the Thread between the heating device and the kuW coupled is wettable with a cooling fluid with as little friction as possible.
  • Another object of the invention is to design the wetting of the thread between the heating device and the cooling device in such a way that the desired thread friction ratios can be set depending on the thread speeds and the thread types.
  • the invention is characterized in that when the thread comes into contact with the wetting surface, thread friction occurs, which depends on the relative speed between the thread and the surface.
  • the wetting surface is designed as a thread running track on the circumference of a rotatable cooling roller.
  • a cooling fluid is held in the thread running track on the circumference of the cooling roller and can be transferred to the thread upon contact. Due to the rotary movement of the cooling roller, on the one hand only a thread friction determined by the relative movement between the thread and the thread running track acts, and on the other hand a continuous, uniform, metered wetting of the thread is achieved.
  • the running thread is constantly contacted with a metered wetted surface of the thread running track.
  • the positive effects of wetting the thread are retained.
  • the metering of the cooling fluid by the rotatable cooling roller is preferably such that when the thread and the cooling fluid come into contact a complete evaporation of the cooling fluid occurs. This ensures that the thread runs absolutely dry into the downstream cooling device, so that, for example, cooling rails or cooling pipes, on the surface of which the thread is guided, do not become dirty. It However, it is also possible to choose the wetting of the thread in such a way that a certain residual moisture is retained in the thread. This variant is particularly applicable to cooling devices which cool the thread without contact by means of a free cooling zone. Any degree of dryness can thus be set on the thread.
  • the cooling roller is driven by a cooling roller drive, which is preferably designed as an electric motor.
  • the cooling roller can be driven both with the direction of rotation in the direction of the thread and with the direction of rotation in the opposite direction of the thread.
  • the cooling roller is driven in the direction of rotation in the thread run.
  • the thread friction can thus be minimized in a state in which the thread and the thread running track of the cooling roll have the same speeds.
  • the cooling roller can also be driven with the direction of rotation counter to the thread run.
  • the thread and the thread track move in the opposite direction, which leads to a high thread friction when wetting the thread.
  • the circumferential speed of the cooling roller can be adjusted to any set thread running speed within the texturing zone, regardless of the direction of rotation being wound.
  • the thread running track is preferably designed as a groove on the circumference of the cooling roller in order to maintain a sufficiently large amount of cooling fluid in the thread running track.
  • the thread is thus guided for wetting within the groove on the circumference of the cooling roller.
  • the cross section of the groove is designed in such a way that adhesion of the cooling fluid in the groove base remains ensured even at higher peripheral speeds of the cooling roller.
  • the cooling fluid is preferably fed to the thread running track on the circumference of the cooling roller by a metering device.
  • the metering device can be designed as an immersion bath which contains a supply of cooling fluid and in which the circumference of the cooling roller is partially immersed.
  • the metering device by a nozzle which is arranged inside the cooling roller or outside the cooling roller in order to supply the cooling fluid to the thread running track.
  • the heating device, the cooling roller and the cooling device are arranged in an essentially straight yarn path.
  • a texturing zone can thus be formed in which additional thread guides and thus thread friction are avoided.
  • Such low-friction texturing zones can, however, also advantageously be achieved with a kinking thread run between the heating device and the cooling device in that the thread is deflected by the cooling roller.
  • a development of the invention is therefore particularly suitable in order to achieve a compact machine structure.
  • the heating device and the cooling device are preferably held in a V-shape in a machine frame, the cooling roller for deflecting the thread being arranged in the tip of the V-shaped arrangement.
  • the cooling roller is provided on the circumference with several thread running tracks running parallel to one another.
  • Each thread track can be assigned a separate metering device or a common metering device.
  • the cooling roller is arranged within a chamber, so that the vapors generated can be removed by a suction device connected to the collecting chamber.
  • FIG. 1 schematically shows a processing point of an exemplary embodiment of the texturing machine according to the invention
  • FIG. 2 schematically shows a cross-sectional view of the wetting device of the texturing machine according to the invention from FIG. 1
  • Fig. 3 schematically shows a cross-sectional view of another

  • the thread 2 is wound into a bobbin 15 in the winding device 12.
  • the winding device 12 consists of a drive roller 13, a traversing device 14 and a spool holder 16.
  • the spool 15 is driven by the drive roller 13 at a substantially constant speed.
  • the wetting device 6 is arranged between the heating device 5 and the cooling device 9 within the texturing zone formed between the first delivery unit 4 and the texturing unit 10.
  • the wetting device 6 has a rotatably mounted cooling roller 7, which will be described in more detail below.
  • the cooling roller 7 is arranged in a collecting chamber 8.
  • the collection chamber 8 is connected in a suction device, not shown here.
  • the thread 2 is drawn within a texturing zone and simultaneously textured after it has been drawn off from the supply spool 1.
  • a false twist is generated on the thread 2 by the texturing unit 10, which is preferably formed by a friction transmitter.
  • the false twist is planted back in the thread 2 against the direction of the thread within the texturing zone, so that the multi-filament thread 2 is crimped by the heating device 6 and the downstream kuM Rhein 9 arranged in the texturing zone.
  • the heating device 6 is preferably designed as a high-temperature heater, the heating surfaces of which are heated at a temperature above the melting temperature of the thread. For this purpose, the thread 2 is guided through the heating device 6 essentially without contact.
  • the heating device 5 by means of a contact heater.
  • the thread is fed into the wetting device 6.
  • the thread 2 enters the collecting chamber 8 via a thread inlet and meets the cooling roller 7 driven at a peripheral speed.
  • a cooling fluid is held in a thread running track on the periphery of the cooling roller 7, through which the heated thread 2 is wetted.
  • the amount of cooling fluid that is applied to the thread 2 is dimensioned such that the thread no longer has any cooling fluid residues after leaving the collecting chamber 8, since these have evaporated within the collecting chamber 8.
  • the resulting steam is discharged through the suction device, not shown here.
  • the cooling device 9 could be designed as a cooling rail or as a cooling tube, on the surface of which the thread is guided with contact. However, it is also possible to form the cooling device through a free cooling zone in which the thread is cooled without contact by external air or ambient air.
  • the thread 2 passes through the texturing unit 10 and is guided through the second delivery mechanism 11 to the winding device 12.
  • the first delivery unit 4 and the second delivery unit 11 are driven at a differential speed, so that the thread 2 is drawn at the same time.
  • the first delivery mechanism 4, the heating device 5, the wetting device 6, the cooling device 9 and the texturing unit 10 are arranged in a thread running plane. In this way, a straight thread run is achieved within the texturing zone, which does not require any additional thread guide elements.

  • the immersion depth of the cooling roller 7 is dimensioned such that the groove cross section of the groove 17 on the circumference of the cooling roller 7 within the immersion bath 22 is completely filled with the cooling fluid 23.
  • the thread 2 is guided in the groove 17 on the circumference of the cooling roller 7.
  • cooling roller 7 Due to the rotation of the cooling roller 7, a quantity of cooling fluid 23 which is constantly held in the groove 17 is challenged from the immersion bath 22 and to the contact point between the running thread 2 and the cooling roller 7.
  • the cooling fluid 23 absorbed by the thread 2 for wetting out of the groove 17 is thus constantly renewed by rotation of the cooling roller 7, a thread friction arising between the groove 17 and the thread 2 being dependent on the relative speed between the thread 2 and the groove 17 ,
  • the cooling roller 7 can be driven by the electric motor 21 at such a peripheral speed that the lowest possible thread friction acts on the thread 2.
