Definitions

  • the spinning rotor 1 is surrounded at a radial distance by a rotor housing 10 which, according to FIG. 1, is provided with a removable but stationary cover 11 and which is arranged through its inner wall 12 at a corresponding distance 13 from the front edge of the cylindrical neck 6 of the spinning rotor 1 is.
  • a cylindrical, conical or other shape protrudes substantially concentrically, which is arranged on the cover body 11, a rotation space 28 being formed between its wall and the parts of the guide surface 16 facing it.
  • a suction channel suction line 20 connected to a vacuum source, not shown.
  • the function of the rotor spinning device according to the invention is as follows: In a disintegration device, not shown, the fibers are combed out of a fiber band with the aid of the clothing tips of the disintegration rollers and transported as individual fibers into the fiber feed channel 19, where they form a stream of individual fibers together with the flowing air.
  • the flow of the individual fibers follows the direction in which the mouth of the guide channel 19 is directed. After exiting the mouth of the feed channel, the fiber stream enters the rotation space 28 between the cylinder wall of the projection 18 and the opposite, conically widening guide surface 16 of the guide body 15.
  • the air flow conveying the fibers from the outlet mouth of the fiber feed channel 19 to the edge 14 requires a different length depending on the given geometric and pneumatic conditions. Under certain circumstances, it may also be sufficient for this to have a fiber guide surface 16 which extends over less than 360 °, so that in such a case this fiber guide surface 16 need not be annular. In any case, however, it should be designed as part of an annular surface and be adapted to the size of the inner circumference of the spinning rotor 1 at the fiber transfer point.
