Definitions

  • 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 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.
  • a texturing device is known from US Pat. No. 3,805,344 which is fed with a thread in chronological succession at different speeds in order to produce irregular effects.
  • GB-A 2 122 229 shows a device in which an already twisted core yarn from rolls is fed to a false twist device.
  • the fancy yarn is fed laterally at a higher speed than the core yarn and is moved up and down along the core yarn.
  • GB-A 2 122 229 thus uses a false twist device to increase the twist of already twisted material.
  • EP-A 0 177 009 works on the same principle as GB-A 2 122 229 discussed above.
  • the pimple yarn forms the pimple by providing a multi-layer winding structure. This is done by delivering the jacket component perpendicular to the core component in a swirl zone of a false twist texturing machine.
  • DE-A 2 616 786 also relates to a device with a false twist section.
  • a fancy yarn with a moving feeding device is applied to a basic thread on this false twist path.
  • this arrangement corresponds to the already discussed EP-A 0 177 009.
  • Basic threads and effect threads are formed from multifilament threads.
  • 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.
  • 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. If the effect lever is at a standstill and the effect thread is fed at the same feed speed as the basic threads, then the effect thread is twisted in the normal way with the basic threads. However, if, for example, the effect lever were moved along the basic threads to be twisted at such a speed that the point at which the effect thread is fed moves at 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 V1 of approximately 7 to 40 m / min.
  • the basic threads 10 are guided through a lower thread guide 14 onto a cop 16.
  • 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.
  • Effect threads 20 and 22 are now fed by a feed drive 24 at a feed speed V2 .
  • the feed drive is represented here by two rollers 25 and 26.
  • the roller 26 is driven by a drive motor 28.
  • the effect threads 20 and 22 are each fed via an effect lever 30 or 32 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 shifted along the running direction of these base threads 10.
  • the effect lever 30 is stationary and the feed speed v z is equal to the throughput speed v i , then the effect thread 20 is twisted with the basic threads 10 in the normal way. 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 at the throughput speed V1 , then the point 38 runs along with the basic threads 10. The effect thread 20 is always fed to the base thread 10 and the yarn twisted therefrom at the same point and wound onto the base thread 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-shaped thread guide 44 is slidably guided in the slot 42 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.
