摘要：
An open-end spinning rotor has a fiber collecting groove which is provided with fine roughenings. The fiber collecting groove includes additional profilings whose peak-to-valley height is at least five times the peak-to-valley height of the roughenings. This arrangement results in an improvement in yarn quality.
