摘要： An open-end spinning device has a spinning rotor defining a fiber collection groove between a rotor bottom and an open-end of the spinning rotor. The rotor further includes a wall extending from the fiber collection groove to the open end of generally less than 6.0 mm. A rotor cover has an extension reaching into the interior of the spinning rotor. The extension includes at least a portion of a fiber feeding channel for feeding a fiber and air mixture into the rotor. A feed surface is disposed essentially parallel to a plane through a fiber collection groove into the extension adjacent the fiber feeding channel so that fibers exiting the feeding channel are directed along the feed surface. The feed surface has a radial dimension so that an open radial distance of less than 4.0 mm exists between the feed surface and the wall or fiber collection groove which is directly radially opposite of the feed surface.
