Abstract
An open-end spinning device has a driven spinning chamber and an outlet tube mounted coaxially with the spinning chamber. A projection is provided on the inner curvilinear surface of the outlet tube, the projection extending along a spiral uncoiling in the direction towards the spinning chamber. The configuration of the projection spiral is chosen in such a manner that the projection of the angle formed between a tangent line to the spiral and a line drawn at right angles to the longitudinal axis of the outlet tube on an imaginary plane drawn at right angles to the longitudinal axis of the outlet tube in the zone of a portion of the spiral most distant from the spinning chamber is between 30.degree. and 40.degree. which corresponds to the angle of turns of the yarn produced in the spinning chamber.
