Definitions

  • one or more threads are conveyed through a texturing nozzle with the aid of a conveying or texturing medium (usually hot air) and textured in the process.
  • a conveying or texturing medium usually hot air
  • the introduction of the thread or threads into the texturing nozzle is a difficult problem. This is due firstly to the fact that relatively thick threads are introduced into relatively small openings of the texturing nozzles at high linear speeds have to. The thread can be sucked into the texturing nozzle by negative pressure. After sucking in, the nozzle is switched to stationary operation, the thread or threads being exposed to the conveying or texturing medium. At the desired high speed of 2000 m / min. and more, however, the insertion process causes considerable thread waste. Efforts have therefore been made to simplify the insertion process and shorten it in time.
  • DE-OS 23 39 603 describes a method in which the inlet opening of the nozzle is enlarged for inserting the thread and reduced again for stationary operation.
  • a device is used in which the inlet opening is enlarged by removing an inner body or is made smaller by adding the inner body.
  • the device has a rather complicated structure because of the movable inner body. It therefore requires a high level of manual dexterity if you want to insert the thread in a very short time.
  • the texturing nozzle is first brought into a position together with the inlet piece, in which the thread is at least approximately perpendicular in the immediate vicinity of the texturing nozzle, the thread is sucked in when the inlet piece is enlarged, and cut off immediately after the suctioning under the texturing nozzle, so that it is sucked into the texturing nozzle, the texturing nozzle is separated from the device required for the suction, the cross section of the inlet opening of the texturing device is reduced to the cross section favorable for the stationary operating phase, and the texturing nozzle is brought into the working position for texturing.
  • the cross-section change of the thread inlet opening takes place with the help of a rotatable cylindrical plug inserted in a so-called inlet piece at the head of the texturing nozzle.
  • the mechanical manufacture of this device is difficult and expensive.
  • the seat of the chick requires tight tolerances for adequate sealing. At an operating temperature of around 400 ° C, chick movement inhibitions cannot be ruled out.
  • Blow-texturing nozzles are suitable for the process.
  • nozzles such as are known from DE-AS 14 35 643 can be used.
  • the method is particularly suitable for the insertion of threads into devices such as are known from DE-AS 20 06 022 or 23 31 045.
  • These nozzles are to be provided with a suitable inlet piece, in which the cross section of the inlet nozzle can be varied.
  • the texturing nozzle and the inlet piece are first brought into a position perpendicular to the thread (which comes from the godet).
  • the downstream end of the texturing nozzle swings into the opened suction device, which is then closed.
  • Due to the negative pressure - according to the invention the supply of the texturing medium is prevented - the thread is sucked in at the inlet piece with a large cross section of the thread inlet opening.
  • Due to the negative pressure in the texturing nozzle the thread is sucked into the nozzle, ie a thread loop is drawn into the thread inlet opening and into the nozzle.
  • the thread is cut off below the texturing nozzle with a thread cutting device, preferably automatic scissors.
  • the thread expediently becomes temporary thereafter picked up by a suction gun.
  • the texturing nozzle is then pivoted into the working position and the gaseous texturing medium is fed to the nozzle.
  • the piston inserted in the inlet piece is pushed up suddenly, thus providing the cross-section of the thread inlet opening that is favorable for the stationary operating phase.
  • the device according to the invention for carrying out the method is constructed in such a way that the inlet piece has a stepped end face with parallel surface sections that intersect the thread inlet opening, and that a piston with an axial opening larger than the thread inlet opening and in operative connection with it is inserted in a height-adjustable manner in the inlet piece.
  • the inlet piece consists of a hollow cylinder, the free end face 2 of which according to the invention has two parallel surface sections 3 and 4 which are offset with respect to one another and which intersect a thread inlet opening 5.
  • the surface section 3 covers the cross section of the hollow cylinder by more than 50%, while the surface section 4 complementary to the cross section of the hollow cylinder consists of a circular ring section with a width corresponding to the jacket thickness of the hollow cylinder.
  • the surface sections preferably overlap and thus enable better guidance of the thread in the suction phase.
  • the inlet piece 1 ie in the hollow cylinder which is connected to the texturing nozzle 10 in a positive and non-positive manner, a piston 6 with an axial opening 7 larger than the thread inlet opening 5 is inserted.
  • the yarn inlet opening and the throughput b statement in the piston to the inlet track, or texturing "The nozzle is arranged centrally.
  • the piston has on its outer surface a longitudinal groove as guide slots 8, into which the guide pin 9.
  • the guide pin which prevents the piston from rotating, is fastened in the hollow cylinder.
  • diameter (d) of a circle of the same area of approximately 2 to approximately 4 mm has proven to be advantageous for the thread inlet opening 5 in the stationary operating state. Since the texturing device can also be fed several threads, for example up to 4 thread strands of the total titer mentioned, even larger diameters are possible.
  • This size of the thread inlet opening must be adapted to the cross-sectional size of the axial throughput b statement 7 in the piston 6 of the inlet piece.
  • the cross-sectional area from the thread inlet opening to the cross-sectional area of the axial opening in the piston is in a ratio of 1: 2 to 1:15, preferably in a ratio of 1: 4 to 1:10.
  • a thread guide tube 14 leads from the thread inlet opening 5 and the axial opening 7 in the piston of the inlet piece 1, through the inlet part of the texturing nozzle 10 (Fig. 2).
  • 16 denotes a connection pipe through which a gaseous medium, preferably hot air of 400 ° C., is introduced into the texturing nozzle under a pressure of 4.8 bar.
