Definitions

  • the present invention relates to a device for texturing continuous filament threads by means of heated flowing media as defined in the preamble of the first claim.
  • each lamella is a flat steel part which is rounded and polished on the thread-carrying end face.
  • Advantageous embodiments consist in the fact that the lamellae in the slot nozzle are exchangeable, respectively. are plugged in.
  • An advantage of the invention is that the rounding of the end faces and the polishing make it possible to design this thread-guiding surface in such a way that the operating conditions, given the friction between the thread and this surface, are subject to significantly fewer changes due to the wear on the end face are.
  • the interchangeable fastening has the further advantage that the slats can be exchanged in the simplest manner after a certain time interval, so that the operating conditions remain within acceptable tolerances.
  • 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 (indicated by dash-dotted lines in FIG. 5) and, on the other hand, for the plug-in reception of the upper (in the viewing direction of FIG. 1) fin ends 24 (FIGS. 1 and 3).
  • the connecting element 13 has an annular insert 26 provided with slots 25 (FIGS. 5 and 6), which is seated firmly in a cylindrical recess 27 of the connecting element 13.
  • the slots 25 have a depth designated T for receiving the upper fin ends 24.
  • a coaxial connecting tube 14 is also provided, which covers the slots 25 with a length m.
  • the upper lamella ends 24 are thus, as indicated in FIG. 3 with dash-dotted lines, on the inner rounded end face 39 on the length m and on the outer end face 40 on the length T radially, with respect to the axis of the device 1, as seen.
  • the tolerances are selected on all sides so that the upper slat end 24 is full, i.e. H. is performed practically without free play in the slot 25.
  • the connecting tube 14 also has a connecting bore 28 which connects the treatment chamber 7 to the compression space 11.
  • the length L of the extension 15 is somewhat longer than the depth t of the slots 29, so that an end face 30 of the lamellae 10 does not lie on the inner one End face 31 of the mouth part rests.
  • each slot 25 resp. 29 is a lamella 10, so that, as shown in FIG. 2, these are arranged in a star shape.
  • the mouth part 16 consists of an annular body 32 provided with the slots 29, a sleeve 33 surrounding this annular body 32, and an inner ring 34.
  • the mouth part 16 also 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 supply 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 35 located between the outer pipe 5 and the inner pipe 6 and from there into the treatment chamber 7.
  • the lamellae 10 are provided with a bead 36.
  • a bead 36 any other measure could be used for the same purpose, for example an offset 37, as indicated by dash-dotted lines in FIG. 4.
  • the type and arrangement of the slots would have to be adapted accordingly.
  • the length of the bead essentially corresponds to the distance between the upper slat end 24 and the extension 15.
  • a screw 38 inserted in the perforated casing tube 9 is used to fasten the mouth part 16.
  • each lamella is a flat steel part, the rounded thread-guiding end face of which is polished and has a radius which corresponds essentially to half the thickness of the lamella.
  • the rounding is polished and has a minimum roughness value Ra of 0.2 u. and preferably from 0.4 g and is advantageously produced by milling.
