In any case, the Abechirorad is driven in the same direction as the rotating ring and at the same or a greater speed than the rotating ring. The outer ring of the AtwChirwrades prevents, on the one hand, that the wires or strands come into contact with the splash at the front end of the spool; on the other hand, it promotes the rotary movement of the individual wires or strands, and it enables the wires or strands because of the bsw on the wires.
