Definitions

  • FIGURE 1 is a schematic view of a conventional pot spinning system showing the apparatus of the present invention in its repose or inactive position;
  • FIGURE 2 is a view of the apparatus of the present invention to an enlarged scale showing the same in its active or operating position;
  • FIGURE 3 is a view in section taken on line 3-3 of FIGURE 2.
  • reference numeral 1 is applied to a spinneret through which a bundle of viscose filaments are extruded into an acid spin bath 3.
  • the delivery pipe for the unregenerated cellulose xanthate is indicated by reference numeral 2.
  • the yarn extruded from spinneret 1 is withdrawn from the spin bath 3 and led over a ICC godet system composed of rollers 6 and 7 and from of tangency to roller 6 into the mouth of a funnel 9 centrally located in the top of a spinning pot 8.
  • the spinning pot 8 is rotated by conventional means and the yarn 4 leaving the funnel 9 is laid up centrifugally in succeeding courses inside the pot.
  • the funnel 9 will be provided with the usual traverse mechanism to reciprocate the same vertically to lay up courses of yarn within the pot.
  • this entraining apparatus may be moved manually between a repose position, FIGURE 1 and a position intercepting the normal vertical yarn path between godet wheel 6 and the mouth of the funnel 9.
  • the entraining apparatus is illustrated in detail in FIGURES 2 and 3. It comprises a tube 10 having a straight portion 10A defining therein a radial slit 11 extending for the full length of the portion 10A.
  • the straight portion 10A of the tube 10 connects and is integral with a portion 10B which has no slit.
  • Portion 10B runs generally horizontally and at. right angles to vertical portion 10A. The connecting bend between them bears reference numeral 100.
  • Two thread guides 14 and 15 are positioned at the opposite ends of the slit 11 in the tube 110. These thread guides are so shaped that they facilitate the threading in of the yarn 4 into the longitudinal slit 11, and moreover, insure that the yarn does not readily escape from the slit. 7
  • a handle 16 in which there is located a handoperated stop-cock 17.
  • the construction of the stopcock 17 is not illustrated because it is well known to those skilled in the art. It sufiices to say that the stopcock controls the flow of water from a flexible hose 18 to the tube 10.
  • the apparatus of FIGURE 2 is kept near the thread 4 in the zone between the roller 6 and the funnel 9 as on a hanger as shown in FIGURE 1.
  • the operator now grasps the handle 16 and lift-s the apparatus olf of the supporting hooks.
  • the apparatus is so manipulated that the thread 4 is guided into the hook-shaped thread guide 14 and along the edge of the disk-shaped thread guide 15 to be finally caught by the sector-shaped recess forming part of guide 15.
  • a current of water is admitted to the tube 10, which exerts a tensile force on the thread 4 so that is is entrained in the portion 10A.
  • the apparatus is displaced in transverse direction, as a result of which the thread 4 is moved to a region beyond the largest radius of the spinning pot 8. Subsequently, the thread 4 ejected from the tube 10 is severed from the yarn package collected in the spinning pot, after which the running yarn is ejected into a discharge trough (not shown).
  • the entraining apparatus may be placed in a holder (not shown), so that the machine operator has both his hands free to replace the fully charged spinning pot by an empty one. During this replacing the thread 4 just continues running from the spinneret 1 over the rollers 6 and 7 and through the portion 10A of the tube 10 to waste.
  • the last stage of the dofling operation consists in that the yarn 4 is removed from the thread guide 14, and in that the dotfing apparatus is so displaced in transverse direction that the yarn 4 can leave it by Way of longitudinal slit 11.
  • the yarn while it is running in its normal path to the point of collection is entrained in a stream of liquid.
  • the yarn is severed adjacent the point of collection and the entrained yarn is bodily displaced to an appropriate Waste region. While it is running to Waste, the collecting package is changed.
  • the supply of fresh yarn is not interrupted and it is not necessary to re-thread any part of the machine except the traverse for the collecting device which, in the illustrated form of the invention, is a funnel.
  • the tube 10 has been displaced from the position coaxially surrounding the normal path of the yarn running to the pot, the liquid flowing therethrough continues to exert a tension on the running thread. As a result, the thread will continue its course through the yarn path ahead of the tube without any disturbance at all.
  • the present invention is of particular advantage in conjunction with a spinning pot because in spinning in a pot it is necessary to wash the yarn into the funnel and this happens absolutely automatically when the tube 10 is brought back into registry with the funnel over the top of an empty pot.
  • a specific advantage of the present invention is that the longitudinal slit may be located in a radial plane which is perpendicular to the plane in which the tube 10 lies. It has been found that if the longitudinal slit is so located, the liquid under pressure does not escape sideways through the slit 11.
  • the yarn withdrawn by the apparatus according to the invention may be guided into a closed vessel or be removed in any other way.
  • Manipulating the apparatus according to the invention may be faciliated if according to the invention around the tube with the closed wall there is provided a handle in which there is a hand-operated stop-cock for the current of liquid.
  • Apparatus for entraining and bodily displacing a running yarn that comprises a tube having straight portion, a slit in a radius thereof extending for the full length of said straight portion, said tube having another portion extending at an angle from one end of said straight portion both portions of said tube being of uniform diameter, and means including a flexible portion to supply water to said tube through said other portion thereof.
