In an open end spinning unit having a stationary frame member and a spinning rotor rotatably supported by the frame member, and in which, during operation of the unit, a flow of gas occurs from the yarn removal opening and fiber inlet opening of the unit to a gas extraction opening thereof, the gas traversing a path surrounding the rotor, a gas flow controlling structure is disposed around the rotor to define a narrow gap with the exterior surface of a portion of the rotor, so that the space adjacent the remainder of the rotor is in communication with the gas flow path only via the narrow gap.
