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, 26360, 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 therefore based on the object to design the texturing nozzle described in the preamble of claim 1 so that the insertion of the thread into the upsetting device is possible without a change in its operating state being 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.
  • a nozzle for texturing a thread which consists 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 on the jacket of a Cone lie, is connected, and wherein the nozzle for the purpose of thread application in an axial plane of the thread channel has a thread insertion slot to be opened and closed.
  • the conveying part consists of two solid components that lie on top of one another with congruent surfaces and form a thread channel between them, which is closed like a lid.
  • the conveying part can consist of two halves which are connected to one another by a hinge and which, during operation, are pressed tightly against one another by strong contact forces.
  • stuffer box it is taken into account that the stuffer box should above all have the best possible design for the outflow of the treatment media and the removal of the thread plug and that this requirement can then no longer be met if the stuffer box is also designed to be massive.
  • the overflow opening which was designed according to the prior art as a conical jacket-shaped gap, is made through at least one, preferably three or four individual bores which meet the annular channel from the thread channel.
  • the ring channel is formed by introducing two ring channel bores on both sides of the thread channel transversely to the parting plane in a plane lying transversely to the parting plane of the nozzle, the bores either meeting at their ends or by further connecting bores which are in the same Level, are connected. This creates a polygonal ring channel that leads around the thread channel.
  • the overflow channels which are designed as oblique bores and lie on a cone jacket, originate from this ring channel.
  • the overflow channels preferably open onto a shoulder with which the narrow input region of the thread channel merges into the further end region of the thread channel.
  • one central nozzle half is designed as a prism, the cross section of which is an isosceles, preferably right-angled triangle or part of the same.
  • Another right-angled isosceles prism (outer prism) is placed on the two congruent side surfaces as the second nozzle half.
  • the thread channel lies in each contact surface.
  • the two nozzle halves are movable relative to one another perpendicular to the parting plane and are preferably pivotally connected by a hinge.
  • a hinge which in particular favors the full superimposition of the two nozzle halves, is formed by making a bore parallel to the thread channel in the two nozzle halves before they are divided. The division then takes place, the parting plane passing through the axis of the thread channel and essentially through the axis of this hinge bore.
  • a rod is inserted as a hinge in the shells of the hinge bore.
  • a slight chamfer of 10 to 30 °, preferably 10 to 20 °, of the end of the parting plane of a nozzle half located at the hinge bore means that the nozzle can be opened with a (depending on the chamfer) a small angle.
  • the running thread can now be inserted or sucked into the thread channel perpendicular to its running direction without the thread having to be cut through.
  • the nozzle according to the invention is surrounded by an insulating chamber which is heated. This way, the nozzle does not get cold during the threading process.
  • the isolation chamber has one or more doors at the front.
  • One of the nozzle halves is preferably connected to the door, so that the nozzle is simultaneously opened and closed with the insulating chamber.
  • the insulating or heating chamber and the nozzle enclosed therein is particularly user-friendly in that the openable nozzle halves are connected to the door or the doors in such a way that the nozzle halves are pressed against the stationary nozzle half by the locking of the door.

  • the angular distances are advantageously such that there is a flow connection between the housing and the sleeve both in the operating position and in the threading position. This can ensure that the thread using the compressed gas also promoted during threading and both the nozzle and the thread are kept at operating temperature during threading.
  • the stuffer box designed as a separate component is connected to one of the components of the conveying part in all exemplary embodiments, but is designed as a separate component and in all cases is provided with an insertion slot which is aligned with the insertion slot of the conveying part in the threading position.
  • the insertion slot of the stuffer box is closed by a sheet which can be inserted into the slot and extends essentially to its inner circumference. It has been found that such a sheet constitutes an excellent closure element, since it leaves slots open on both sides, the width of which can essentially be adapted to the perforation or slitting of the stuffer box. In this way, a homogeneous flow field can be achieved in the stuffer box.
  • the stuffer box can be clamped by radial clamping forces in such a way that the threading slot is closed during operation.

  • the insertion slot 28 of the stuffer box is meshed with the E inlegschlitz 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 on its face that of the stuffer box is facing, two pins 41.1 and 41.2. These pins engage in grooves 42.1 and 42.2, which are introduced into the corresponding end face of the stuffer box.
  • grooves are offset from the insertion slot 28 of the stuffer box by approximately 90 ° in both directions, as the top view of FIG. 20 shows. Furthermore, 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.
  • the stuffer box When the pins 41.1 and 41.2 are in these branches, the stuffer box is in the operating position, the insertion slot 28 of the stuffer box is closed and the insertion slot of the sleeve 52 is essentially 90 ° offset from the insertion slot 71 of the housing block 51.
