Definitions

  • the invention relates to a device for blast texturing of at least one multifilament yarn, with a guide body which contains a through-bore which has a conical section on an inlet side, and with a needle body which has a continuous yarn channel which is approximately coaxially aligned with the bore of the guide body contains, extends with one end into said conical section and has on this end a conical peripheral surface which one with the wall of the conical section
  • the passage gap for the blowing medium between the needle body and the guide body should have a predetermined width depending on the ITiter of the yarn, which is in the range of approximately 0.12 to 0.4 mm.
  • the width of the passage gap should always have its optimal value. The precision required for this is difficult, however reach and keep up.
  • the guide body and / or the needle body have therefore been arranged axially adjustable in a housing of the device in order to be able to adjust the width of the passage gap by axial adjustment.
  • these devices it is practically not possible to set the width of the passage gap precisely and reproducibly to a desired value. There is also a risk that the setting will change over time.
  • the object of the invention is generally to design the device specified at the outset in such a way that a high and uniform texturing quality is achieved and is also guaranteed over a longer period of time.
  • the object is achieved in the device according to the invention in such a way that the axial position of the guide body with respect to the needle body is fixed in that the guide body and the needle body are pressed against one another in the axial direction by a force load.
  • the invention therefore dispenses with making the guide body and the needle body axially adjustable with respect to one another, but instead presses the two bodies against one another with a preferably elastic force of predetermined size. This inevitably results in a passage gap of predetermined, constant width between the needle body and the guide body. In addition, it is possible without difficulty to hold the two bodies in such a way that the wall of the conical section of the bore in the guide body and the conical peripheral surface on the needle body are exactly coaxial with one another.
  • the impact body is preferably not axially adjustable with respect to the guide body by the distance to be able to adjust between the outlet mouth of the bore of the guide body and the impact body.
  • the impact body can be exchangeably held on a holder and can also be pivoted into a threading position that is distant from the outlet opening of the bore of the guide body.
  • FIG. 1 schematically shows a longitudinal section through a blowing texturing device
  • Fig. 5 in a view corresponding to a section of Fig. 1, on a larger scale a variant of the device and
  • FIG. 7 in a view similar to Fig. 1 - on a somewhat smaller scale - the exit area of another variant of the blow texturing device and
  • FIG. 8 shows a view of the variant according to FIG. 7 from the left in FIG. 7.
  • the device for blowing texturing of a multifilament yarn (or simultaneously of two or more multifilament yarns) shown schematically in FIGS. 1 to 4 has a Deitmaschine 1, for example made of ceramic material, which contains a through hole for the passage of multifilament yarn and blowing medium.
  • This bore has a conical section 2 on an inlet side
  • the apex angle of the cone shape is in the usual way between 30 and 120 °, for example as shown at about 60 °.
  • the device has a needle body 3 which contains a continuous yarn channel 4 which is approximately coaxially aligned with the bore of the guide body 1.
  • the needle body 3 extends with one end into the conical section 2 of the bore of the guide body
  • the passage gap 6 should have a precisely predetermined width, which depends on the titer of the yarn to be textured to run through the yarn channel 4 and is in the range of approximately 0.12 to 0.4 mm.
  • the axial position of the guide body 1 with respect to the needle body 3 is fixed in accordance with the invention in that the guide body 1 and the needle body 3 are pressed against one another in the axial direction by a force load.
  • the guide body 1 and the needle body 3 are guided with their peripheral surfaces in a cylindrical sleeve 7 and touch one another, in the preferred manner, directly on an annular surface 8.
  • annular surface 8 between the two Bodies 1 and 3 for example to arrange a washer of predetermined thickness, which can be exchangeable.
  • the annular contact surface 8 could also be conical in order to additionally center the two bodies 1 and 3 with respect to one another.
  • the guide body 1 abuts a flange 7.1 of the sleeve 7, while the needle body 3 in one on the outside of the
  • Sleeve 7 guided housing 9 is held, e.g. as described below using a bayonet catch. Sits in a bore in the housing 9
  • a connecting line 14 leads from a compressed air connection 13 in the housing 9 to the left side of the flange 7.2 acting as a piston, so that the pressure of the blown air supplied also pushes the sleeve 7 to the right with respect to the housing 9.
  • the connecting line 14 is not visible in FIG. 3, but its position is indicated here by a dash-dotted line.
  • the compressed air connection 13 of the housing 9 is connected via a lateral opening 15 in the sleeve 7 to a circumferential recess 16 in the needle body 3. From this recess 16 an axially parallel feed bore 17 for the blown air starts, which opens into the annular space 18 surrounding the needle body 3 in front of the passage 6.
  • an impact body 20 is arranged, which, for example, has the shape of a cylindrical sleeve as shown.
  • the sleeve 20 is held interchangeably on a mandrel 21 which is seated in a body 23 which can be pivoted about an axis 22.
  • the pivot axis 22 is fixed in a on the sleeve 7 Holder 24 held.
  • a compression spring 25 is also arranged, which presses a ball 26 into a recess 27 in the body 23.
  • the body 23 is fixed with the mandrel 21 in the operating position shown, in which the sleeve 20 serving as a baffle body has a predetermined distance from the outlet opening of the bore of the guide body 1
  • the sleeve 20 has a small distance. This distance can be changed in that the sleeve 20 is exchanged for another sleeve with a larger or smaller outside diameter.
  • the body 23 with the mandrel 21 - after overcoming the force of the compression spring 25 - can be pivoted about the axis 22 into a threading position, in which the ball 26 into a second locking recess 28 snaps into the body 23.
  • the sleeve 20 serving as an impact body is then removed from the guide body 1, so that a suction gun can be placed in front of its outlet mouth.
  • the needle body 3 is held in the housing 9 by means of a bayonet catch.
  • the needle body 3 carries two radial projections 29 and 30 which engage behind inward radial projections 31 and 32 of a bayonet ring 33 held in the housing 9.
  • the bayonet ring 33 is detachably arranged in the housing 9 and held, for example, by means of a snap ring 34.
  • the yarn G emerging from the outlet mouth of the bore of the guide body 1 and striking the impact body 20 is deflected on the impact body 2o in such a way that it extends from the axis of the yarn channel 4 and
  • the needle body 3 can be in a position opposite to that shown for this purpose position rotated by 180 ° about the axis can be inserted into the sleeve 7.
  • the recess 16 in the needle body 3 extends approximately symmetrically with respect to the air supply bore 17 in the circumferential direction over an angle ⁇ (FIG. 3 from 180 to 270 °), so that this recess 16 both in the illustrated position of the needle body 3 and also in its 180 ° rotated position communicates with the lateral air inlet opening 15 of the sleeve 7.
  • ⁇ angle
  • Bayonet lock can be designed so that the needle body 3 can only be used in one position.
  • the projection 31 of the bayonet ring 33 is measured in the circumferential direction wider than the projection 32.
  • the projections 29 and 30 of the needle body 3 have a distance from each other on one side (right in Fig. 4), which is the Width of the projection 31 corresponds, and on the other side (left in Fig. 4) a smaller distance, which corresponds to the width of the projection 32.
  • the needle body 3 can therefore only be used in a position in which the larger distance between the projections 29 and 30 is aligned with the wider projection 31, and then rotated by 90 ° into the position shown. This rotation is 90, for example, by stops 29.1 and 30.1 arranged on the projections 29 and 30, which cooperate with the projections 31 and 32 limited.
  • the bayonet ring 33 (after removing the snap ring 34) has to be removed from the housing 9 and rotated by 180 ° again.
  • the two positions of the bayonet ring 33 rotated relative to one another by 180 ° are fixed, for example, by a cam 33.1 on the bayonet ring 33, which is received in one of two diametrically opposite recesses 9.1 and 9.2 in the housing 9.
  • FIG. 5 shows a variant on a larger scale in a view corresponding to a section from FIG. 1.
  • the needle body 3 ' is in direct contact with the guide body 1; However, the needle body 3 'does not touch the end face of the guide body 1, but the wall of the conical bore section 2.
