ABSTRACT:
Fibers delivered in a freely floating state in a fiber transport passage are to be laid in a predetermined disposition on a friction spinning element, such as a friction spinning drum or disc. For this purpose, an opening region of the fiber transport passage is provided with a converging portion in which the airstream is supplementarily accelerated relative to a preceding acceleration. This supplementary acceleration serves to assist in bringing the fibers into the predetermined disposition on the friction spinning drum. The friction spinning device comprises an opening roller which is rotatably supported in a housing. The housing is connected to the fiber transport passage. The opening of the fiber transport passage extends close to a cylindrical surface of the friction spinning drum. The fibers leaving the opening are transported on the friction spinning drum towards a yarn formation position where they are twisted into a yarn which is withdrawn in a selectable withdrawal direction by withdrawal rollers.
