Definitions

  • the present invention relates to an open-end spinning device with an interchangeable spinning rotor, a feed device for feeding a fiber assembly, a device for dissolving the fibers in individual fibers, a cover containing a thread take-off tube and a fiber feed channel and a part partially in the rotor protruding lid continuation.
  • the object of the invention is now to create a simple and cost-saving device which allows the use of rotors with diameters of different sizes while maintaining the parameters important for spinning technology for yarn production.
  • the drawing shows an open-end spinning rotor with an inserted ⁇ attachment.
  • a fiber feed channel 1 Through a fiber feed channel 1, individual fibers are fed by means of a transport air stream onto a sliding surface 2 of a spinning rotor 4 (shown in phantom) on a rotating shaft 3. The fibers slide along the sliding surface 2 into the fiber collecting channel 5 in the largest rotor inner diameter D1 and are twisted together into a thread and drawn out of the rotor 4 through the thread draw-off tube 6 which is concentric to the rotor shaft 3.
  • the ring 11 which sits snugly and without transition on the lid extension 10 and is fastened by means of a locking screw 13, the optimal spinning conditions are restored.
  • the ring 11 has a bore 12, the axis of which can run parallel or substantially parallel to the plane of rotation of the rotor.
  • the diameter of the bore 12 is larger than that of the fiber feed channel 1 at its end 9.
  • the bore 12 can also have a different cross-section, for example a rectangular cross-section.
  • the fiber / air stream undergoes formation by this initial and arrangement of the hole 12 corresponds to a slight 'deflection in the direction of the plane of rotation of the rotor 7, whereby the impingement of the fibers on the sliding surface 8 of the rotor 7 that on the sliding surface 2 of the rotor. 4
  • the enlargement of the cross section of the fiber feed channel 1 in the bore 12 also results in a desired distribution of the fed fibers near the sliding surface 8

Abstract

Dans le dispositif a filer "open end", le couvercle comprend, du cote du rotor ouvert (4, 7) une saillie centrale (10) traversee, d'une part, par le conduit de sortie (6) du fil et, d'autre part, par le conduit d'alimentation (I) des fibres. Un anneau interchangeable (11) entoure la saillie du couvercle permettant d'adapter la saillie a des rotors de plus grands diametres.
