ABSTRACT:
An open-end friction spinning machine is disclosed which has a plurality of adjacently arranged spinning units, each spinning unit including two adjacently arranged friction rollers driven in the same rotational direction and forming a wedge-shaped yarn forming gap therebetween. At least the friction roller rotating out of the wedge-shaped gap exhibits a closed cover surface. To assure consistent predetermined yarn characteristics, friction roller conditioning devices are disclosed for conditioning the friction surfaces of the friction rollers with closed cover surfaces.
