A dust-removing mechanism in an open-end spinning frame has a dust-removing chamber into which a dust-removing opening opens, the dust-removing opening being defined by a rear wall disposed upstream in the direction of rotation of the combing roller and having an edge and a front wall disposed downstream in the direction, there being an angle alpha formed between first and second lines passing through the front and rear wall edges and the center of the combing roller, an angle beta formed between a third line passing through the center of the combing roller and the center of an opening in the rotor and a fourth line passing through the center of the combing roller perpendicularly to the third line, an angle UPSILON formed between a surface of the front wall and a fifth line extending parallel to the fourth line through the front wall edge, and an angle delta formed between a surface of the rear wall and a sixth line extending parallel to the fourth line through the rear wall edge, the angles being in the following ranges: 40 DEG </= alpha </=45 DEG 0 DEG </= beta </=5 DEG 40 DEG </= UPSILON </=45 DEG 0 DEG </= delta </=20 DEG .
