Definitions

  • the apparatus for the production of such multistrand yarn includes two plates or blocks having abutting surfaces, at least one of the abutting surfaces having recesses therein defining at least two straight or curved conduits for passage of a rapidly moving fluid in opposite directions, impinging a yarn traveling in a plane substantially parallel to the rapidly moving fluid.

  • the fluid jet of compressed air for example, is recovered at the outlet of the resonance box so as to make the fluid jet again act against the yarn so as to produce a further interlacement of the same.
  • such a process has an additional difficulty and disadvantage associated therewith in that it is difficult to position the yarn which is subjected to the double effect of the fluid jet causing both translational and vibratory movement. Accordingly, control in such case is difficult and critical to effectively carry out the interlacement of the yarn.
  • the yarn which is to be interlaced is placed in a zone of controlled turbulence, the axes of rotation being substantially parallel to the direction of advancement of the yarn.
  • the action of the fluid jet is not pinpointed and the device used in such process generally comprises a conduit for passage of the yarn into which the delivery conduit or conduit for the fluid opens, generally in a plane substantially perpendicular to the direction of advancement of the yarn.
  • conduits of special crosssection have been proposed for the passage of the yarn in order to obviate the foregoing disadvantage
  • special configurations have not been found industrially satisfactory since they add further complications to the system and, therefore, make the process difficult to carry out on an industrial scale.
  • the foregoing disadvantages of previous processes and devices for carrying out such processes have been overcome in accordance with the present invention whereby a process and device are provided for interlacing parallel strands of yarn, particularly adapted for interlacing such strands at high speeds.

  • a yarn 10 drawn from a spool 12 passes between a set of delivery rolls 14 and 16 and a set of draw rolls l8 and 20 on a pin 22, before passing through interlacing device 24 in which the strands of the yarn are interlaced by impingement with a rapidly moving fluid.
  • interlacing device 24 After passing through interlacing device 24, the yarn, the strands of which have been interlaced, passes over roll 26 before being wound on a cop 28 by a device with a ring 30 and traveler 32.
  • interlacing device 24 consists of two blocks or plates, 40 and 42, in this case parallelepipedal blocks or plates.

  • the rapidly moving fluid preferably compressed air, is introduced through inlet pipe 56 into two branches 60 and 62 of conduits ending in two curved conduits 64 and 66, preferably of a smaller cross-section than branches 60 and 62.
  • conduits 64 and 66 open into a further conduit 68 for passage of the yarn.
  • the plane of conduits 64 and 66 is substantially parallel to the plane of conduit 68. Accordingly, the rapidly moving fluid passing through conduits 64 and 66 impinges the yarn traveling through conduit 68 in a plane substantially parallel to the travel of the yarn 10.

  • conduits 64 and 66 open into conduit 68 and have a portion in common therewith.
  • Projections 44 and 46 are so placed in conduits 64 and 66 as to obstruct the same, thus preventing any recycling of the rapidly moving fluid. Accordingly, the rapidly moving fluid exits the interlacing device of the present invention through hall or port 70 through conduit 72 connected to conduits 64 and 66.
  • conduits of FIG. 2 have been shown as circular. It is to be noted, however, that such conduits can be in any curved or straight configuration which allows the rapidly moving fluid to impinge the yarn from opposite directions and in a plane substantially parallel to movement of the yarn. When utilizing curved conduits, it is preferred that the same are circular since such shape can be easily machined.
  • recesses in the bottom plate 42 are preferably rectangular in crosssection. However, here again, any other suitable shape can be advantageously utilized. Similarly, while it has been shown in FIG. 2 that the recesses are entirely within the bottom plate, the recesses forming the conduits for passage of the rapidly moving fluid and yarn can be formed in both the upper plate 40 and bottom plate 42. Such embodiment is seen in FIG. 3.

  • the curved conduits have a portion in common with the conduit through which the yarn passes, and the conduits are so arranged that jets of the rapidly moving fluid impinge the yarn from opposite directions.
  • the plane of the rapidly moving fluid is substantially parallel to the plane of movement of the yarn.
  • FIG. 4 illustrates an embodiment of the present invention wherein the curved conduits for delivery of the rapidly moving fluid have been moved to opposite sides of the interlacing device or nozzle. As seen in FIG. 2,
  • the rapidly moving fluid is introduced into the interlacing device or nozzle through delivery conduits 80 and 82, which delivery conduits end in curved conduits 84 and 86, which curved conduits are of smaller cross-section than the delivery conduits 80 and 82.

  • the device of FIG. 5 is similar to that of FIG. 4 except that those portions of the interlacing device or nozzle situated on the side opposite those portions having the curved conduit have been eliminated. Accordingly, the yarn moves freely between the portions of the interlacing device or nozzle having the curved conduits and the rapidly moving fluid after impinging yarn l0 escapes freely.
  • the device of FIG. 6 is similar to those of FIGS. 4 and 5, except that each of the portions of the interlacing device or nozzle now contains a curved conduit. Accordingly, the device of FIG. 6 shows four curved conduits serving to deliver the rapidly moving fluid to a zone in which the same impinges the yarn. As seen in FIG. 6, the rapidly moving fluid is introduced through delivery conduits 80, 82, 90 and 92. The delivery conduits 80, 82, 90 and 92 end in curved conduits 84, 86, 94 and 96, the curved conduits being of smaller crosssection than the delivery conduits. The curved conduits are obstructed by studs 44, 46, 98 and 100, preventing recycling of the rapidly moving fluid.
  • each of the curved conduits has a portion in common with the conduit through which the yarn travels and atleast two of the jets impinge the yarn in opposite directions. As seen in FIG. 6, there are two pairs of jets impinging the yarn from opposite directions.
  • FIGS. 2 through 6 each illustrate the employment of circular conduits. It is to be noted, however, that where the curved conduits are employed, the same need not be circular. Any other suitable configuration can be adapted to the interlacing device or nozzle of the present invention. In addition, straight conduits can be employed. This is illustrated in FIG. 7.
  • the rapidly moving fluid is delivered through four oblique grooves or conduits 110.
