ABSTRACT:
An open-end spinning device (1) with a spinning rotor (3) whose spinning cup rotates at a high speed in a rotor housing (2) loaded by a vacuum and closed by a yarn guide plate. A fiber guide conduit (14), arranged between a sliver opening device (26) and the spinning cup, has a wall section with an elevated coefficient of friction comprised of conduit sections (29, 30) of different surface roughnesses. The wall of the entrance-side section (29) of the fiber guide conduit has a distinctly greater surface roughness (R.sub.t) than the wall of the exit-side section (30) of the fiber guide conduit.
