Definitions

  • the present invention relates to a device for increasing and regulating the Thread pulls, in particular a Entwirrumblenbremse, at one Texturierspinnvorraum with at least one texturing device according to the Override of claim 1.
  • the temperature of the plug has to be when stretched below a certain polymer dependent value. If the plug is stretched out at too high a temperature, the thread loses immediately part of the ripple again. One tries, therefore, the cooling angle and thus to choose the residence time of the plug on the screen drum as large as possible. The yarn drawn out again to a thread slides over a sliding angle on the Screen drum. This is due to friction on the screen a certain thread train generated. If one chooses the first angle, the cooling angle, as large as possible, takes the second angle, the slip angle, inevitably.
  • the threading after the sieve drum is for the reasons listed above in the Usually too low for a stable run on the following conveyor rollers.
  • the thread string after the screen drum by inserting a Thread brake increased accordingly.
  • the thread brake is usually around friction brakes.

  • one of the texturing device 4 downstream thread running path 26 is present, on which the thread 7th at least once on a free thread length 24 of 0.5 m - 10 m, preferably 1 to 5, in particular 2 to 5 m, the friction with a gaseous and / or fluid medium is suspended, wherein before the free thread length 24 of the thread is not by friction Thread guide elements is braked. In other words, closes the free Threadline over which the thread of no mechanical elements is acted upon or deflected, directly to the texturing device 4 and their Screen drum 6 without the thread has contact with such elements.
  • Free thread length is to be understood as a length on which the thread does not come into contact with a thread guide element. This length can be up to 10 meters long.
  • the thread running path has at least the length of a free thread length.
  • the thread can be repeatedly passed back and forth and thus repeatedly pass through the corresponding free thread length,
  • the thread is on the yarn path over at least two pulleys guided, the distance determines the free thread length.
  • the thread sets on the free length of thread surrounding him medium, for example Air, in a movement.
  • This train can be guided in parallel by pulleys act more free thread lengths of the thread and thus increase the friction. Perhaps Resulting frictional heat is dissipated by the surrounding medium immediately, and it can not come to a friction-induced heating of the thread.
  • means are present which the gaseous and / or fluid medium along the free thread length in a directed Move movement, preferably opposite or transverse to the thread running direction.
  • a directed Move movement preferably opposite or transverse to the thread running direction.
  • An additional braking effect on the thread can be achieved.
  • the means that set the medium in motion For example, it could be a blower, a pump, a supply line of the Medium in the vicinity of the free thread length or a Abbowschkeit the Media act.
  • the medium can be brought so targeted in the vicinity of at least one free thread length.
  • the chamber should be laid out in such a way that the thread is passed comfortably through and the gaseous and / or fluid medium within the chamber is set in motion can be.
  • the chamber preferably has a movable lid, the serves to insert the thread, the chamber is advantageously provided with openings for provided the inlet or outlet of the thread, the chamber preferably has openings for a supply and a discharge of the gaseous and / or fluid medium.
  • the Thread on one or more sections of the free thread length within a or more tubular elements extends.
  • the tubular elements are used for Guiding, especially if the thread is not in the running state or the thread pull diminishes due to other reasons. In the current state of touched Thread usually not the tubular elements.
  • the at least one tubular element is preferably one lockable longitudinal slot for inserting the thread provided, and one or a plurality of supply channels for the supply of the gaseous and / or fluid medium.
  • the effectiveness of the device according to the invention can still be improved if it comprises a control device with which the thread train to be achieved is controllable.
  • the control device for example, the free thread length can be varied, but it can also speed the directional movement, the Composition, the amount or the temperature of the gaseous and / or fluid Medium be regulated.
  • control device comprises a control loop, which ensures a constant value of the thread train. This possesses the Control device means for detecting the thread train.
  • FIG. 1 shows a section of a texturing spinning device 1 according to the prior art Technology.
  • the yarn to be processed 7 is first on a pair of stretching rollers. 2 stretched and then led into a texturizer 4. There arises a plug 5, which is placed on a rotating screen drum 6 after leaving the texturing device 4 becomes. It remains above the cooling angle K on the screen drum 6. After going through of the cooling angle K, the plug at the end A of the cooling angle K becomes a Thread 7 pulled out. The extended thread 7 then slides within the angle R on the screen drum 6. The friction between thread 7 and screen drum 6 is generated a thread string, so that the thread 7 with the corresponding thread string the Sieve drum 6 leaves. As already mentioned, this string is usually too deep for the next, not shown in the figure, process stages.
  • the yarn brake 3 comprises a plurality of Thread guide elements E, where the thread 7 undergoes friction. At the Running into the next process step, the thread 7 has a threadline with a higher value than before the thread brake.
  • FIG. 2 shows by way of example a first embodiment of the invention.
  • the thread 7 via an inventive Entwirrumblenbremse 23 out.
  • This consists of a yarn path 26, on which the thread is guided over guide rollers 10 and 11, so that the thread 7th three times a free thread length 24 passes through, which is approximately the distance 27 of Deflection pulleys 10 and 11 corresponds.
  • the yarn guide 9 only serves to, the Position of the thread at the inlet point on the subsequent conveyor roller 8 determine.
  • the length of the yarn path 26 and thus the free thread length 24 is on the Thread speed and the desired thread train tuned. She can between 0.5 m and 10 m, preferably between 1 m and 5 m.
  • the thread 7 on the inventive Entwirrumblenbremse 23 further cooled and not by the mechanically heated frictional heat at the yarn brake reheated.
  • the aerodynamically generated braking effect is very thread-friendly and will not due to the contamination and / or wear of thread-contacting surfaces as in the yarn brake of the prior art influenced. The braking effect therefore remains stable and does not change over time.
  • Figure 3 shows a schematic representation of another embodiment of a inventive Entwirrumblenbremse 23 with forced cooling.
