Definitions

  • the present invention relates to a texturing nozzle for continuous filament threads, as defined in the preamble of the first claim.
  • a texturing nozzle is known according to the preamble of the first claim, in which the texturing part of the nozzle consists of radially arranged lamellae which are connected with the upstream end in a connecting part and with the downstream end in a mouth part.
  • slots are provided in the connection and in the mouth part according to the lamella cross-section, in which slots the lamellae are guided practically without play.
  • the slots and thus in each case the slot base can be contaminated by preparation liquids which are used on the continuous filament threads, so that at a change in the slats can occur.
  • An advantage of the invention is that the ability to clean the slots in the base enables the slots to be designed more freely, for example by blowing out the slots from the inlet and from the base.
  • a texturing nozzle 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 texturing nozzle 1 following the treatment part 4, comprises a curling part 8 with a perforated casing 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 can be connected and separated.
  • 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 direction of the filament or in the direction of view of FIG. 1) fin ends 24 of the fin 10 ( 1 and 3).
  • the connecting element 13 consists of two identical, half-ring-shaped, joined halves (see FIG. 6), into each of which a half-ring-shaped insert 26, each with a semi-ring-shaped sleeve part 34 with slots 25 (FIGS. 5 and 6), is fitted, these inserts 26 each sit in a semi-annular recess 27 of the two halves of the connecting element 13 and are firmly connected to them.
  • a connection can e.g. generated by gluing, soldering or welding.
  • the two halves of the connecting element 13 rest on an inner support shoulder 14 provided on the outer tube 5 (shown as a detail in FIGS. 5 and 10) and are clamped in the outer tube 5 by the screws 23.
  • the slots 25 have a depth designated T for receiving the upper fin ends 24.
  • the radial centering of these slat ends 24 takes place in that the play between the width B of the slots 25 and the width B.1 of the slat ends 24 is selected such that the slat ends 24 are guided in the slot with practically no play when inserted into the slots.
  • the immersion depth M of the upper fin ends 24 is, as indicated in FIG. 5 with dash-dotted lines, smaller than the slot depth T.
  • each insert 26 has a semi-ring-shaped depression, designated as cleaning shaft 50, with a depth F and with the same width as the slot width B.
  • cleaning shaft 50 With the help of this cleaning shaft, it is possible to dismantle each slot base, ie to clean and separate the state of the connecting element 13 from the outer tube 5 and the perforated jacket tube 9 with, for example, compressed air.
  • the tolerances of the slits 25 and of the slat part inserted in the slit are selected on all sides so that the upper slat end 24 is full, i.e. is guided practically without free play in the corresponding slot 25.
  • the connecting element 13 also has a connecting bore 28 which connects the treatment chamber 7 to the stuffer box 11.
  • the lower end, formed as an extension 15 (seen with a view of FIGS. 3 and 12), of the lamellae 10 also fits snugly into slots 29 of a mouth part 16.
  • the length L of the extension 15 is somewhat longer than the immersion depth t (FIG. 7) of the extension 15, so that an end face 30 (FIGS. 3 and 12) of the lamellae 10 does not rest on the inner end face 31 of the mouth part.
  • the tolerances of the extension 15 and the slots 29 are selected on all sides so that the extension 15 is full, i.e. is guided practically without free play in the corresponding slot 29.
  • each slot 25 resp. 29 is a lamella 10, so that, as shown in FIG. 2, they are arranged in a radiation pattern.
  • the mouth part 16 consists of two identical halves and these two halves each consisting of a semi-ring-shaped insert body 32 provided with the slots 29 and a semi-circular sleeve part 33 surrounding this insert body 32.
  • Each insert body 32 is firmly connected to a semi-ring-shaped sleeve part 33, this connection, as mentioned for the connecting element 13, with the aid of a solder -, welding or gluing process can happen.
  • each insert body 32 has a cleaning shaft 51, the width of which corresponds to the width B.2 of the slots 29 and which has a depth F.1, viewed in the direction K (FIG. 7).
  • the depth F and the depth F.1 are chosen empirically such that the 50 and. 51 accumulated dirt e.g. can be blown away with compressed air.
  • 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 feed the treatment medium into the device 1.
  • the treatment medium is supplied via a supply channel 21 in the connecting piece 19 the annular space located between the outer tube 5 and the inner tube 6 is conveyed and from there into the treatment chamber 7.
  • a screw 35 inserted in the perforated casing tube 9 is used to fasten the mouth part 16.
  • FIGS. 9 to 12 show variants of FIGS. 1, 3, 5 and 6, the same parts being provided with the same reference symbols.
  • the variants assume that the lamella 110 shown in FIG. 12 has, in addition to the lower extension 15, as seen in FIG. 12, an upper extension 115 with a length L.1 at the opposite end.
  • these slots 125 In order to be able to insert the upper part of the lamella 110 containing the extension 115 with an immersion depth M.1 into one of the slots 125 provided in semicircular inserts 126, these slots 125 have an L-shaped shape shown in FIG. 10.
  • the slot depth T.1 or T.2 (Fig. 10) greater than the immersion depth M.1 or M.2.
  • the half-ring-shaped inserts 126 are connected to the half-ring-shaped sleeve parts 34 of the connecting element 13 in the same way as the inserts 26.
  • the tolerances of the slots 125 and of the upper parts 124 of the slats 110 inserted into the slots 125 are selected on all sides so that the upper slat end 124 of each slat 110 full, ie is guided practically without free play in the corresponding slot 125.
  • each half-ring-shaped insert 126 has a half-ring-shaped cleaning shaft 52, which corresponds to a depth F.2 (FIG. 10) and a width B.2 (FIG. 12) of the extension 115 Width.
  • the depth F.2 is empirically chosen, as previously described for the depth F.1.
  • the slots 25, respectively. 125 and 29 are advantageously generated by means of spark erosion. It is also possible to use the milling process for the slots 25 and 29.
