Definitions

  • the present invention relates to a device that interlaces a multifilament yarn.
  • the Japanese Patent No. 3034649 discloses a crimping device that entangles multifilament yarns with each other.
  • the crimping device comprises a nozzle body portion 1 and a baffle body portion 2.
  • a yarn passage 6 is formed to extend linearly through the nozzle body portion 1 and the baffle body portion 2.
  • the yarn passage 6 communicates with a blow nozzle 7 provided in the nozzle body portion 1 and with an insertion slit 8.
  • the insertion slit 8 is positioned between a flat surface of the nozzle body portion 1 and a flat surface of the baffle body portion 2.
  • the yarn passage 6 is formed of a groove formed in the nozzle body portion 1 and comprising a first recessed wall surface 11 and a groove formed in the baffle body portion 2 and comprising a second recessed wall surface 12. See p. 3, 5th column, 11. 47 to 48 and 6th column, 11. 2 to 13, and Figure 4 in the Japanese Patent No. 3034649 .
  • the insertion slit 8 is positioned close to the center of a cross section of the yarn passage 6. This is expected to pose various problems. That is, first, the yarn traveling close to the center of the cross section of the yarn passage 6 is likely to jump out through the insertion slit 8. Second, a fluid injected against the yarn through the blow nozzle 7 is likely to be blown out through the insertion slit 8.
  • a main object of the present invention is to provide an interlacing device that can solve various problems resulting from a slit through which a yarn is inserted into a yarn traveling space.
  • a first aspect of the present invention provides an interlacing device configured as follows. That is, the interlacing device comprises a first member having a first surface and a fluid injecting hole formed in the first surface so that a fluid is injected through the fluid injecting hole, and a second member having a second surface.
  • the first surface and the second surface are arranged opposite each other to form a yarn traveling space as a space through which a yarn to be interlaced travels so that the yarn traveling space communicates with the fluid injecting hole and to form a yarn inserting gap as a gap through which the yarn can be inserted into the yarn traveling space in a direction perpendicular to a traveling direction of the yarn.
  • a groove is formed in the second surface, and the groove and the first surface are combined together to form the yarn traveling space.
  • the groove extends inward in a direction perpendicular to the second surface.
  • the gap is located upstream of the fluid injected toward a groove bottom of the groove and away from the groove bottom of the groove.
  • a second aspect of the present invention provides an interlacing device configured as follows. That is, the interlacing device comprises a first member having a first surface and a fluid injecting hole formed in the first surface so that a fluid is injected through the fluid injecting hole, and a second member having a second surface and a groove formed in the second surface.
  • the first surface and the second surface are arranged opposite each other so as to combine the groove and the first surface together to form a yarn traveling space as a space through which a yarn to be interlaced travels so that the yarn traveling space communicates with the fluid injecting hole and to form a yarn inserting gap as a gap through which the yarn can be inserted into the yarn traveling space in a direction perpendicular to a traveling direction of the yarn.
  • the groove extends inward in a direction perpendicular to the second surface.
  • the gap is located upstream of the fluid injected toward a groove bottom of the groove and away from the groove bottom of the groove.
  • a third aspect of the present invention provides an interlacing device configured as follows. That is, interlacing pieces each having a first surface and a second surface are provided in a row so that the first surface and second surface are arranged opposite each other. A fluid injecting hole is formed in the first surface of each of the interlacing pieces. A groove is formed in the second surface of each of the interlacing pieces.
  • the first surface and the second surface are arranged opposite each other so as to combine the groove and the first surface together to form a yarn traveling space as a space through which a yarn to be interlaced travels so that the yarn traveling space communicates with the fluid injecting hole and to form a yarn inserting gap as a gap through which the yarn can be inserted into the yarn traveling space in a direction perpendicular to a traveling direction of the yarn.
  • the groove extends inward in a direction perpendicular to the second surface. In the above-described configuration, the gap is located upstream of the fluid injected toward a groove bottom of the groove and away from the groove bottom of the groove.
  • the above-described interlacing device is further configured as follows.
  • the area in which the fluid injected into the yarn traveling space is mostly present or mostly flows is formed line-symmetrically with respect to the direction in which the fluid injecting hole is drilled. This arrangement enables the symmetric flow of the fluid in the area, which is expected to be useful for interlacing performance.
  • the above-described interlacing device is further configured as follows.
  • the fluid injecting hole is formed to have a cross section that is flat along the traveling direction of the yarn. This arrangement allows the fluid to be injected against the yarn traveling through the yarn traveling space, for a long time. This improves the interlacing performance.

  • the availability of the sectional shape described in (2) enables the symmetric flow of the fluid in the area (inner portion 18b), which is expected to be useful for interlacing performance. Since the slit 12 is composed of the combination of the groove and the surface, the interlacing device 100 can be very easily manufactured.
  • the inner portion 18b is formed line-symmetrically with respect to the line C.
  • the flow of the fluid in the yarn traveling space 18 is expected to be formed line-symmetrically with respect to the line C.
