Definitions

  • ABSTRACT OF THE DISCLOSURE Apparatus for continuous spinning utilizing an airstream issuing into a spinning chamber.
  • Said spinning chamber having oppositely formed inclined walls which form a V and said apparatus having a guide tube for depositing opened sliver-like fiber in said V-shaped area.
  • the spinning chamber having vanes at the top thereof to facilitate discharge of air toward a suction box connected to a source of negative pressure.
  • the principal object of the present invention is to overcome the above mentioned disadvantages by providing a new method and apparatus for spinning by utilizing an airstream for obtaining opening and parallelism of fibers and twisting of the yarn.
  • FIG. 1 is a sectional view of the spinning apparatus forming one embodiment of the present invention
  • FIG. 2 is a perspective view of a modified form of the spinning rotor employed in the apparatus
  • FIG. 3 is a sectional view of another modified form of the spinning apparatus according to the invention.
  • FIG. 4 is a schematic perspective view of the spinning 3,411,283 Patented Nov. 19, 1968 "ice apparatus and a packageupon which the spun yarn is wound;
  • FIG. 5 is a somewhat enlarged sectional view of the spinning rotor shown in FIG. 1, showing the path of motion of the airstream and the yarn fibers in the spinning chamber of the spinning rotor.
  • the sliver-like fiber fed from a pair of feed rollers 1 is introduced into and conveyed through a small guide tube 2, in which the sliver-like fiber is conveyed and opened while maintaining its parallelism by being entrained by a high speed airstream under negative pressure.
  • This guide tube 2 is securely mounted on an immovable support member or casing 4.
  • the lower end of the guide tube 2 is formed into a nozzle 5, from which the airstream together with the fiber is ejected.
  • a spinning rotor 8 having a spinning chamber formed in the upper portion thereof.
  • Said spinning chamber consists of a lower funnel-like conical space having a conical inner wall 6 and an upper oonical space having a conical inner wall 7, said lower and upper conical spaces joining each other at the bases of the cones as shown, forming a V-shaped inner circumferential portion 9 at crossing of the generation lines of the lower and upper cones.
  • the nozzle 5 of the guide tube 2 is directed toward the inner wall of the spinning chamber and disposed in the vicinity of said V-shaped portion 9, i.e., the maximum diameter portion, so that the yarn fiber coming from the nozzle 5 will reach the V-shaped portion in a minimum length of time and distance. Consequently, it is possible to prevent any floating of the yarn fiber.
  • the nozzle 5 may be bent outwardly and so arranged that the fiber entrained by the airstream and ejected therefrom will be directed against the inner conical wall 7 in the vicinity of the V-shaped portion 9. By such arrangement, it is possible to prevent disturbance of the yarn fiber.
  • the upper portion of the spinning rotor 8 is enclosed in the casing 4 forming a suction box 10 which is connected at one end to any source of negative pressure through a pipe 10'.
  • a suction box 10 which is connected at one end to any source of negative pressure through a pipe 10'.
  • the depending tubular stem 8' of the spinning rotor 8 is a continuation of the lower conical space 11 having inner conical wall 6, and is provided with a spinneret tube 12.
  • the sliver-like fiber fed from the feed rollers 1 is introduced into the guide tube 2 and is conveyed through the same by the action of the high speed airstream, whereby the fiber is opened while maintaining the parallelism thereof.
  • the speed of the airstream may be regulated by adjusting the negative pressure in the suction box 10.
  • the fiber coming from the nozzle 5 of the guide tube 2, as entrained by the airstream, will contact and proceed along the upper conical wall 7 of the spinning chamber of the spinning rotor 8 by the action of centrifugal force. As the nozzle 5 opens in the 'vicinity of the wall 7, the succeeding yarn fiber coming from the nozzle will impinge against the preceding yarn fiber 14 which is in contact with the conical wall 7.
  • the yarn fiber Will be deflected in the circumferential direction, contacting the wall 7, and will be put in parallel with the preceding yarn fiber 14.
  • said fiber will be moved toward the V-shaped portion 9 of the spinning chamber, so that the path of the motion of the fiber can be shown by the spiral line a in FIG. 5.
  • the motion of the fiber is being guided by the conical wall 7, said motion will not be disturbed at all. Since the nozzle 5 is disposed in the vicinity of the upper conical wall 7, there is no tendency of the fiber to move into a floating position in the spinning chamber, but the same will instantly contact to the upper conical wall 7, while maintaining the parallelism thereof.
  • the speed of the airstream coming from the nozzle 5 of the guide tube 2 will be quickly reduced due to the fact that the volume of the spinning chamber is much larger than the cross-sectional area of the guide tube 2, and that it is not aimed directly against the V-shaped portion 9. So, the airstream in the spinning chamber will not disturb the yarn fiber in the spinning chamber.
  • the airstream will take the path shown by line b in FIG. 5 and, through the passage 3 and the suction box 10, will be discharged to the atmosphere.
  • the leading end of the twisted yarn as formed from the yarn fiber 14 will be subjected to tension due to the extremely high centrifugal force upon the yarn fiber 14 by high speed rotation of the spinning rotor 8, so that the twisted yarn will be given enough tension to be conveyed toward the spinneret tube 12.
  • the yarn fiber 14 will be rotated in the direction of the arrow by the high speed rotation of the spinning rotor 8, so that the yarn fiber 14 and the twist yarn will be subjected to twisting action between the V-shaped portion 9 and the package 13.
  • the twist yarn proceeding into the nonrotatable spinneret tube 12 will be pressed against the lower conical wall 6 by the action of centrifugal force, so that the leading portion of the twist yarn will be further subjected to twisting action.
  • the twist yarn will successively pull the yarn fiber coming from the nozzle 5 in the vicinity of the V-shaped portion 9, and the yarn passing through the non-rotatable spinneret tube 12 will be wound upon the package 13.
  • an immovable spinneret tube 12 (or resistance tube) is positioned in the rotating tubular stem 8.
  • This tube 12 has at its upper end a necked-in passage 15.
  • the provision of the non-rotatable tube 12 is for the purpose of slightly gripping the yarn at the uper point of the spinneret tube so as to limit the twisting action to the free portion of the yarn fiber.
  • the twisting of the yarn fiber 14 will occur mainly between the V-shaped portion 9 and the upper end of the non-rotatable tube 12, i.e. for the limited length of the yarn fiber 14, increasing unity among fibers and thereby facilitating continued winding operations.
  • the top portion is provided with a plurality of projections or vanes 16 and depressions alternately arranged.
  • the provision of these vanes 16 will aid the discharge of air from the spinning chamber of the spinning rotor according to the high speed rotation of the spinning rotor. Consequently, negative pressure required for inducing the operative airstream can be considerably reduced.
  • the support member 4' is detachably mounted upon the suction box 10, while the casing 4 in FIG. 1 is securely mounted.
  • This detachable mounting of the support member 4 is preferred in order to facilitate inspection and cleaning of the interior of the spinning rotor 8.
  • the airstream will readily pass through the clearance between the support member 4 and the inner edge of the top of the spinning rotor in the direction of the arrow.
  • a spinning apparatus comprising a guide tube having at one end a nozzle and adapted to guide and convey a sliver-like fiber toward said nozzle by means of an airstream, a high speed rotatable spinning rotor provided with a spinning chamber having a mouth at the top thereof for discharging air and having a centrally arranged depending tubular stem, a non-rotatable spinneret tube positioned in said stem, said spinning chamber having a lower funnel-like conical space and an upper conical space above said lower funnel-like conical space with the bases of said spaces joining each other to form a V-shaped portion at the crossing of the generation lines for the conical inner walls of said chamber, said guide tube having a nozzle on the lower end thereof opening into said spinning chamber adjacent said V-shaped portion, a plurality of vanes at the edge of said top mouth of the spinning chamber, and a source of negative pressure connected to the space between said vanes, whereby the yarn fiber in said spinning chamber is subjected to centrifugal force and contacts the inner wall of the
  • a spinning apparatus as recited in claim 1 further comprising a support member to which said guide tube is fixed, and a suction box around said spinning rotor and on which said support member is detachably mounted.
