Abstract
An open-end spinning apparatus with a spinning rotor having an interior wall, a yarn takeoff channel opening and a fiber feed channel opening communicating with the interior of the spinning rotor. A suction opening (5, 50, 51) is connected to a source of reduced pressure and has its open end directed to the interior wall of the spinning rotor. The suction opening is positioned so that a suction air stream flowing therethrough is separated by a screen from the yarn takeoff channel opening and the fiber feed channel opening.
