Definitions

  • the invention relates to a method for the automatic insertion of one or more fast-running threads through a narrow opening, the thread first being passed transversely in front of the opening, being separated in the thread running direction after the opening and being conveyed through the opening with a propellant gas jet acting perpendicularly to the previous thread running direction is and an apparatus for performing the method.
  • the spun fiber In the production of synthetic threads, the spun fiber must pass through treatment devices which have a narrow entrance opening, for example a texturing or a false twist nozzle.
  • the introduction of a thread through the openings mentioned is referred to in the text below as “threading on” the thread, the narrow opening as “nozzle” or “texturing nozzle.”
  • Devices, such as pulling needles or loops, are known with which a thread can be threaded on. It is also known to "shoot" the separated thread running in front of the opening through the opening with a gas jet, but the known devices and methods can only be used if the thread speed is not too high impulse transmitted to the thread does not extend to deflect the thread and the thread becomes tangled in the delivery plant.
  • the gas jet If the gas jet is replaced by a liquid jet, the inside of the nozzle becomes moist and must first be dried by the treatment medium. The nozzle is cooled, and it takes several minutes until the target temperature is reached again in which waste is produced.
  • the invention has for its object to insert threads running at high speed into a narrow opening without thread and device being wetted with liquid.
  • the method should also be applicable if the thread speed is above 3000 m / min.
  • the object is achieved procedurally in that a propellant gas jet, the cross section of which is so large that the jet no longer passes completely through the narrow opening, is blown onto the thread and this jet is split into a central one by an upstream arrangement before the narrow opening Ray that passes through the narrow opening and into rays that are derived in front of the narrow opening.
  • the device for carrying out the method consists in that the arrangement upstream of the narrow opening consists of a thread inlet channel which widens into an annular space, and in the annular space on the side there are bores or channels leading outwards and a nozzle opposite the upstream arrangement is available, from which a propellant gas jet can emerge, the diameter of which in the area of the upstream arrangement is larger than the narrow opening.
  • An arrangement 2 is arranged upstream of the opening 1 of the texturing nozzle. This contains a thread inlet channel 3, which widens into an annular space 4. On the lateral circumference of the annular space 4 there are bores 5 for gas discharge.
  • FIGs 2 and 3 the thread path and the gas flow is shown schematically.
  • the thread 6 runs in front of the thread inlet channel 3.
  • the propellant nozzle 7 is acted upon by propellant gas via the valve 8 and the thread 6 is separated from the thread running direction after the thread inlet channel 3 by any cutting device 9.
  • the thread is transported into the thread inlet channel 3 by the propellant gas flowing out of 7.
  • the driving jet is split up so that a central jet transports the thread 6 into the opening 1 of the texturing nozzle and that part of the driving steel gets out through the lateral bores 5.
  • the (heated) propellant gas is used for thread treatment.
  • the yarn is conveyed further by the inflowing gas.
  • the thread 150 dtex / 34 f has a running speed of 3500 m / min. It is to be applied to a texturing nozzle whose nozzle inlet diameter is 1 mm.
  • the thread inlet channel diameter is 1.3 mm, the diameter of the annular space 2.6 mm at a depth of 2 mm.
  • the marginal jets of the propellant gas are partially discharged through two holes, each 0.8 mm in diameter.
  • the driving nozzle has a diameter of 0.7 mm:
  • the blowing agent is steam with a pre-pressure of 9 bar and a temperature of 230 ° C.
