Abstract (en)
[origin: WO8602955A1] An open-end spinning device with two friction rolls driven in the same direction, which form a spinning gap, whereby the friction roll that rotates into the spinning gap is designed as a suction roll, and in which the fibres which are fed into the spinning gap are twisted into a thread in a yarn-forming region. At least one of the friction rolls (1, 2) possesses, in the spinning gap (3) in the yarn-forming region (G), a cut-out (I) which is subjected to an underpressure. The width of the cut-out (I) extends in the peripheral direction of the yarn-forming region (G) over the plane (A) linking the axes of the friction rolls (1, 2) on the side which moves away from the spinning gap (3).
