Definitions

  • the invention relates to a device for interlacing multifilament yarns, with a body that contains a continuous yarn channel, into which at least one blowing nozzle and a threading slot each open laterally, see e.g. document GB-A-2 178 072.
  • the object of the invention is to design the device specified at the outset in such a way that the required high swirl density can be achieved with a high regularity of the fixed point distances - without the occurrence of individual larger fixed point distances or opening lengths - and with very low blowing air consumption per swirl node.
  • swirling devices with predominantly round (cylindrical) yarn channels are suitable for low to medium swirling densities, but for higher swirling densities, swirling devices with yarn channels are used which generally have a flat impact surface for the blowing jet from the blowing nozzle, in some cases yes also have up to three flat surfaces.
  • the invention is based on the knowledge that not only the wall surfaces of the yarn channel must contain at least two flat partial surfaces, but that it is also necessary to guide the yarn within the intermingling device very precisely, for which purpose in the body of the device at both ends of the Yarn channel thread guide must be used.
  • the yarn should only come into contact with the second concave wall surface, which lies opposite the mouth of the blow nozzle, but hardly with the first concave wall surface containing the mouth of the blow nozzle.
  • the edge of the opening of the threading slot, from which the first wall surface extends is at a greater distance from the plane of symmetry than the other edge of the opening of the threading slot.
  • the part of the yarn channel delimited by the first wall surface serves, in addition to receiving the blowing nozzle, mainly for guiding the blowing medium towards the two ends of the yarn channel in a manner that is easy to swirl.
  • lateral outlet openings can be provided, which are seen in front of the mouth of the blowing nozzle Thread guides start from the thread channel.
  • the body of the device according to the invention can be formed in one or more parts.
  • the body can be composed of a nozzle body part containing the blow nozzle with the first concave wall surface and an impact body part with the second concave wall surface which is exchangeably fastened to the nozzle body part.
  • other swirl density ranges can be achieved by simply changing the impact body part under the same operating conditions.
  • the swirl density can be reduced by half.
  • the interchangeable impact body parts can also consist of different materials and / or have differently machined surfaces.
  • a device for intermingling multifilament yarns has a two-part body with a nozzle body part 1 and an impact body part 2, which is attached to the nozzle body part 1 by means of a screw 3 and two centering pins 4 and 5.
  • a yarn channel 6 extends straight through the assembled body 1, 2, into which at least one blowing nozzle 7 contained in the nozzle body part 1 and a threading slot 8 each open laterally.
  • the threading slot 8 lies between flat surfaces of the nozzle body part 1 and the impact body part 2.
  • the yarn channel 6 is formed by a groove with a first concave wall surface 11 in the nozzle body part 1 and a groove with a second concave wall surface 12 in the impact body part 2.
  • the concave wall surface in the impact body part 2 is symmetrical with respect to one Axis A of the yarn channel containing plane of symmetry E, and is composed of three flat partial surfaces 12.1, 12.2 and 12.3.
  • the axis A of the yarn channel can be defined as the (straight) line containing the centroids of the yarn channel cross sections.)
  • the partial surfaces 12.1 and 12.2 are approximately perpendicular to the partial surface 12.3; the groove in the impact body part 2 is therefore approximately rectangular in cross section.
  • the concave wall surface in the nozzle body part 1 is likewise symmetrical with respect to the plane of symmetry E, it is composed of two flat partial surfaces 11.1 and 11.2 inclined to the symmetry plane E and a cylindrical partial surface 11.3 connecting the partial surfaces 11.1 and 11.2.
  • the blowing nozzle 7 is also symmetrical with respect to the plane of symmetry E. It can be perpendicular to the yarn channel axis A as shown or could form an angle with this axis between approximately 70 and 90 °.
  • the nozzle body part 1 could also contain more than one blowing nozzle; in such a case, each blowing nozzle could be symmetrical with respect to the plane of symmetry E or, for example, two blowing nozzles could also be arranged symmetrically opposite one another with respect to the plane of symmetry E.
  • the partial surface 11.2 of the first concave wall surface starts from a first (lower) edge of the opening of the threading slot 8, and the partial surface 12.2 of the second concave wall surface starts from the second (upper) edge of the opening of the threading slot 8.
  • the first edge of the mouth of the threading slot has a greater distance from the plane of symmetry E than the second edge of this mouth.
  • the partial surface 11.1 which is symmetrical to the partial surface 11.2 extends to a line which is symmetrically opposite the first edge of the mouth of the threading slot 8. Between this line and the edge of the partial surface 12.1, which is symmetrically opposite the second edge of the opening of the threading slot 8, transition wall surfaces are provided on the nozzle body part 1 and / or on the impact body part 2. Instead, however, a second slot could also be provided, the mouth of which would be symmetrically opposite the mouth of the threading slot 8.
  • At least one multifilament yarn M (FIG. 3) runs in the longitudinal direction through the yarn channel 6 is moved, swirled by a jet of blowing medium, for example compressed air and / or water vapor, entering the yarn channel 6 from the blowing nozzle 7.
  • a jet of blowing medium for example compressed air and / or water vapor
  • the yarn must be guided very precisely within the yarn channel 6.
  • 6 thread guides 13 and 14 are inserted in the nozzle body part 1 at both ends of the yarn channel, for example in the form of glued-in sapphire pins.
  • the thread guides 13 and 14 extend across the yarn channel 6 in such a way that a thread placed over these thread guides 13 and 14 in the tensioned state has no contact with the first concave wall surface 11, but one measured by this first concave wall surface 11 in the plane of symmetry E.
  • Distance h which is preferably 5 to 50% of the distance H measured in the plane of symmetry E from the first concave wall surface 11 to the second concave wall surface 12. It is advantageous to guide the multifilament yarn M (or several multifilament yarns) in the direction of one of the thread guides 13 or 14 and to pull it away from the other thread guide, which directions lie approximately in the plane of symmetry E and with the axis A of the thread channel angle ⁇ of 2 form up to 20 °.
  • the thread guides (as seen from the mouth of the blowing nozzle 7) have lateral outlet openings for the blowing medium. 1 and 3, these outlet openings are, for example, grooves 15 and 16 and / or bores 17 and 18 in the nozzle body part 1, which emanate from the groove of the nozzle body part 1 which has the first concave wall surface 11.
  • the cross section of the outlet openings is larger than the part of the cross section of the yarn channel 6 blocked by the respective thread guide 13 or 14 or larger than the projection surface in the direction of the yarn channel axis A of the part of the respective thread guide 13 or 14 projecting into the profile of the yarn channel 6.
  • FIG. 5 to 11 show views similar to FIG. 4 for modified embodiments of the two-part body of the swirling device.
  • the groove forming part of the yarn channel in the nozzle body part and / or the groove in the impact body part has different cross-sectional shapes, but which are always symmetrical with respect to the plane of symmetry E.
  • the groove in the nozzle body part 1 and the first concave wall surface have the same shape as described with reference to FIG. 4.
  • the second concave wall surface in the impact body part 2.1 consists of a cylindrical surface 12.4. If the impact body part 2 of FIG. 4 is replaced by the impact body part 2.1 according to FIG. 5, the same nozzle body part 1 is used to obtain a device which produces a lower intermingling density in a multifilament yarn under the same operating conditions.
  • 6 and 7 show embodiments in which the groove in the nozzle body part 1.1 has a modified shape.
  • the first concave wall surface is composed of three flat partial surfaces 11.4, 11.5 and 11.6. 6 can be used with the impact body part 2 described with reference to FIG. 4 or according to FIG. 7 with the impact body part 2.1 described with reference to FIG. 5.
  • the groove in the nozzle body part 1.2 has yet another cross-sectional shape.
  • the first concave wall surface in the nozzle body part 1.2 consists of a cylindrical surface 11.7.
  • the nozzle body part 1.2 is used according to FIG. 8 with the impact body part 2 described with reference to FIG. 4, but according to FIG. 9 with a impact body part 2.2 in which the second concave wall surface is composed of three flat partial surfaces 12.5, 12.6 and 12.7 and two of these planar partial surfaces in pairs connecting cylindrical partial surfaces 12.8 and 12.9.
  • FIG. 10 and 11 show that the impact body part 2.2 described with reference to FIG. 9 can also be used with the nozzle body part 1 according to FIG. 4 or with the nozzle body part 1.1 according to FIG. 6.
  • the impact body part is always attached to the nozzle body part in an exchangeable manner; however, it is clear that the impact body part could also be permanently connected to the nozzle body part or could be formed in one piece with it.
  • the profile of the yarn channel is limited by two concave wall surfaces, each of which is symmetrical with respect to the plane of symmetry E and which together contain at least four partial surfaces, at least two of which are flat. 4, these partial surfaces are the flat partial surfaces 11.1, 11.2, 12.1, 12.2 and 12.3 and the cylindrical partial surface 11.3.
  • these partial surfaces are the flat partial surfaces 11.1, 11.2, 12.1, 12.2 and 12.3 and the cylindrical partial surface 11.3.
