Definitions

  • the present invention relates to a device for texturing continuous filament threads by means of a heated flowing medium, as defined in the preamble of claim 1.
  • Patent specification No. 527 931 a device according to the preamble of the first claim is known, in which a crimping part is formed by star-shaped lamellae, which are fixedly arranged with a narrow side facing the compressed thread. These slats are fixed at both ends by rings and kept at a distance so that the medium necessary for texturing can escape between the slats.
  • this object is achieved in that a means for supplying gas to the side of the stuffer box provides a single gas jet nozzle for stowing the filament threads at the beginning or after the crimp is interrupted, which is arranged in such a way that the gas jet is thus in one direction the stuffer box can be blown in, which is different from the conveying direction of the threads.
  • the advantages of the invention are that the accumulation can be carried out in the simplest manner and with absolute reliability, and that this air jet no longer interferes with the crimp once formed.
  • a device for texturing 1 comprises a thread insertion part 2 with a thread insertion channel 3, a treatment part 4 with an outer tube 5 and an inner tube 6 located therein, which contains a treatment chamber 7.
  • the device 1 following the treatment part 4, comprises a crimp part 8 with a perforated jacket tube 9 and fins 10 located therein, which delimit a compression space 11.
  • the thread insertion part 2 is connected by means of a thread 12 to the outer tube 5, while the outer tube 5 and the perforated tube 9 are centered by an inner connecting element 13 and by means of screws 22 and. 23 are interconnectable.
  • the connecting element 13 further serves, on the one hand, for the fixed reception of the inner tube 6 and, on the other hand, for the pluggable reception of the upper (in the viewing direction of FIG. 1) fin ends 24 (FIG. 1).
  • a connecting tube 14 also has a connecting bore 15, which connects the treatment chamber 7 to the compression space 11.
  • the mouth part 16 furthermore has a mouth bore 17 through which the crimped thread (not shown) and part of the treatment medium exit.
  • a connecting piece 19 fastened in the outer tube 5 by means of a thread 20 serves to feed the treatment medium into the device 1.
  • the treatment medium is conveyed via a supply channel 21 present in the connecting piece 19 into an annular space 25 located between the outer pipe 5 and the inner pipe 6 and from there into the treatment chamber 7.
  • the lower extension 27, seen in the fiber conveying direction F, of the lamellae 10 is received in the mouth part 16.
  • the mouth part 16 is held by means of a fixing screw 26 received in the perforated casing tube 9.
  • the perforated casing tube 9 has a nozzle part 50 attached to it, which is provided with a thread 51 at its end facing away from the perforated casing 9 for receiving a pipe connection part 52.
  • This pipe connection part 52 in turn serves to receive a pressure pipe 53, which is connected to a changeover valve 54 is.
  • the switching valve 54 is connected to a pressure source 55.
  • a seal 56 is provided in the interior of the pipe connection part.
  • the nozzle part 50 has a compressed gas supply bore 57, a nozzle cone 58 and an injection nozzle 59.
  • the conveying direction G of the injected gas forms an obtuse angle with the conveying direction F of the continuous filament threads, viewed in this conveying direction.
  • the gas emitted by the pressure source 55 is already reduced to a predetermined pressure determined by tests, so that the effect of this gas jet does not cause any malfunctions in operation or disadvantages on the filament.
  • gas jet can either be directed directly between two fins 10 or onto one without ascertaining a significant difference in the accumulation effect.
  • the gas can be continuously blown in after the accumulation without a disturbance of the texturing effect being ascertained.
  • oil-free air can be used as the gas.
