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
