Title: Yarn guide device for an open-end spinning machine

Abstract: This invention relates to a yarn guide device for an open-end spinning frame, wherein said yarn guide device comprises a navel with a yarn guide opening arranged around the rotational axis of the rotor, and a guide roller with a yarn contact surface positioned substantially on an extension of the rotational axis of the rotor. The spun yarn is taken out through the navel substantially along the rotational axis of the rotor and is deflected for the first time as it passes along the guide roller.
