PCT No. PCT/DE85/00447 Sec. 371 Date Jun. 30, 1986 Sec. 102(e) Date Jun. 30, 1986 PCT Filed Nov. 11, 1985 PCT Pub. No. WO86/02955 PCT Pub. Date May 22, 1986.The invention concerns an open-end spinning device with two friction rollers driven in the same direction and forming a spinning nip of which the roller rotating towards the spinning nip is a suction roller and in which the fibers fed into the spinning nip are twisted together into a thread in a yarn forming zone. At least one of the friction rollers (1, 2) is provided with a sector (I) subjected to negative air pressure in the spinning nip, in the range of the yarn forming zone (G). The width of said sector (I) extends, in the peripheral sense, from the yarn forming zone (G) to beyond the plane (A) connecting the axes of the friction rollers (1, 2) towards the side opposite to the spinning nip (3).
