Definitions

  • the invention relates to a nozzle for texturing a thread, consisting of a conveying part and a perforated stuffer box, the conveying part having a thread channel which is connected to the gas supply via an annular channel and overflow openings which lie on the surface of a cone, and wherein the nozzle has an opening and closing thread insertion slot for the purpose of thread application in an axial plane of the thread channel.
  • DE-AS 1 435 653 describes a method for the continuous upsetting of thermoplastic threads, for the implementation of which a device is used in which the thread is conveyed through a warm fluid medium by means of an injector into a stuffer box with a gas-permeable side wall and forms a thread plug, whereupon it is taken up and wound up at the end of the device.
  • the European patent applications 108 205, 123 072, 26 360, 110 359 have also made known attempts to make the texturing nozzle openable by producing the texturing nozzle from two halves which are pressed together in a sealed manner during operation.
  • the nozzles are treated as a mechanical unit. This is only possible if the conveying part on the one hand and the adjoining stuffer box on the other hand are designed with the same strength. For this reason, special measures must be taken for the perforated stuffer box in order to achieve the required strength.
  • the invention is based on the object, the texturing nozzle described in the preamble of claim 1 so that the insertion of the thread in the upsetting device is possible without a change in its operating state would be necessary.
  • the disadvantages of the known devices and methods are to be avoided and an openable nozzle is to be created which ensures simple and quick insertion of the running thread into the nozzle without impairing its performance.
  • the construction of the nozzle should in particular enable a streamlined construction of the stuffer box, so that the flow of the treatment medium is guaranteed in an optimal manner and is not impaired by the fact that the stuffer box must be particularly solid to achieve sufficient strength.

This creates a polygonal ring channel that leads around the thread channel.

  • the stuffer box is a relatively thin tube. This tube is provided with longitudinal slots 25 over a partial length. These longitudinal slots are milled by a side milling cutter, which is partially immersed in the jacket of the stuffer box 23. The longitudinal slots serve the purpose of letting the heating gas (hot air, steam) escape from the stuffer box.
  • the stuffer box 23 is also provided with an insertion slot 28. This insertion slot 28 extends over the entire length of the stuffer box. The insertion slot 28 of the stuffer box meshes with the insertion slot 71 in the housing block.
  • the stuffer box has a flange 36.
  • the flange has elongated holes 38.1 and 38.2 offset by 90 °. In these elongated holes, the flange is screwed to the housing block 51 in such a way that the wall of the stuffer box 23 can execute a certain radial movement to open and close the insertion slot 28.
  • the quill has two pins 41.1 and 41.2 on its end, which faces the stuffer box. These pins engage in grooves 42.1 and 42.2, which are introduced into the corresponding end face of the stuffer box. These grooves are offset from the insertion slot 28 of the stuffer box by approximately 90 ° in both directions, as the top view of FIG.
  • the grooves 42.1 and 42.2 are eccentric. Therefore, when the sleeve 52 is rotated relative to the housing block 51 and the stuffer box 23, the pins 41.1 and 41.2 radially compress the stuffer box wall or spread apart the stuffer box wall radially.
  • the last branch 43.1 or 43.2 of the stuffer box runs essentially in the circumferential direction.
