Definitions

  • the invention relates to a device for producing a yarn with randomly arranged and / or designed effects, comprising a twisting device in which basic threads to be twisted are passed through a central thread guide at a throughput speed and twisted by winding onto a fast rotating cop
  • Yarns consist of basic threads that are twisted around each other by a twisting movement and thereby twisted.
  • devices are used in which the basic threads are fed through a central thread guide and are then wound onto a rapidly rotating conical winding body, the cop.
  • the thread guide sits approximately on the axis of the cop.
  • the basic threads describe a conical surface and are twisted together. This is a normal twisting device.
  • US Pat. No. 3,805,344 discloses a texturing device to which a thread is fed in chronological succession at different speeds in order to produce irregular effects.
  • the invention is based, to apply effects of the type described in one operation with the twisting in a yarn which is produced by twisting a plurality of threads.
  • this object is achieved in that at least one effect thread is also guided onto the cops via an effect lever which can be moved in the running direction of the basic threads and is twisted with the basic threads and the effect lever can be moved by an effect lever drive which is controlled by an electronic control unit with a random generator .
  • the effect thread is fed to the twisting device transversely to the running direction of the "basic threads" to be twisted and twisted with it by the twisting device.
  • the effect lever stops and the effect thread with the same Chen feed speed is fed like the basic threads, then the effect thread is twisted as normal with the basic threads. If, however, the effect lever were moved, for example, along the basic threads to be twisted at such a speed that the point at which the effect thread is fed moves with the feed speed of the basic threads, then the effect thread is practically "wound up" only at one point of the yarn. , a small knot is created.
  • the device according to the invention can be easily attached to existing twisting devices.
  • Embodiments of the invention are the subject of the dependent claims.
  • FIG. 1 there are 10 basic threads which are to be twisted into a yarn.
  • the basic threads 10 are guided through an upper, central thread guide 12.
  • the basic threads 10 are fed at a throughput speed v 1 of about 7 to 40 m / min.
  • the basic threads 10 are guided through a lower thread guide 14 onto a cop 16.
  • This is a truncated cone-shaped winding body, which is driven by a cop drive 18 at about 2500 to 5000 revolutions per minute.
  • the upper thread guide 12 lies approximately on the axis of rotation of the cop 16.
  • the base threads 10 thereby describe a conical surface and are twisted around one another and twisted together. This is a common twisting device.
  • the feed drive is represented here by two rollers 25 and 26.
  • the roller 26 is driven by a drive motor 28 driven.
  • the effect threads 20 and 22 are fed via an effect lever 30 and 32, respectively, transversely to the running direction of the base threads 10 and twisted with them.
  • These effect levers 30 and 32 can be deflected by an effect lever drive 34, as indicated by the double arrow 26 in FIG. 1.
  • the points 38 and 40 in which the effect threads 20 and 22 are fed to the base threads 10 to be twisted, can be displaced along the running direction of these base threads 10.
  • the effect lever 30 stands still and the feed speed v2 is equal to the throughput speed v1, then the effect thread 20 is twisted with the basic threads 10 as normal. If the effect lever 30 is pivoted clockwise by the effect lever drive 34 at such an angular speed that the point 38 runs from top to bottom with the throughput speed v 1, then the point 38 runs with the basic threads 10. The effect thread 20 is always fed in at the same place of the basic threads 10 and the yarn twisted therefrom and wound onto the basic threads 10. This creates a very concentrated knot at this point. If the point 38 moves at a lower speed than the throughput speed, then a greater length of fancy threads per unit length of yarn is fed on a finite section than from the basic threads. The effect thread 20 then forms a more or less elongated effect. The effect thread 22 acts accordingly with the effect lever 32.
  • the effect lever 30 has a slot 42 running in the longitudinal direction.
  • a sleeve Sen-shaped thread guide 44 guided by means of a circumferential groove 46.
  • the already twisted base threads 10 are passed through the thread guide 44 from top to bottom.
  • the effect thread 20 is fed through a side slot 48.
  • the effect thread 20 is twisted or wound around the base threads 10 during the rotational movement of the cop 16.
  • the effect lever drive 34 and the feed drive 24 are controlled by an electronic control unit 50.
  • the electronic control unit 50 contains a random generator.
  • the control unit 50 accordingly controls the feed speed such as the angular speed of the effect levers 30 and 32 during the downward and upward movement and the times of the speed changes and the deflection of the effect levers at random within certain, predetermined limits.
  • the commanded downward speed is therefore always within a predetermined, reasonable speed interval, but follows a random distribution within this speed interval.
