Abstract: In order to make the start-up of spinning easier and to obtain a spinning triangular zone which is easily accessible and easily observed, the feeding in of fibers is provided at a rear triangular zone 35 whereas the twisted spun yarn 6 is withdrawn from the other triangular zone 36 in parallel to the plane 34 of the closest distance between the two spinning members 1, 2. The fibers have to pass a narrow section, since the triangular zone 36 is disposed oppositely to the triangular zone 35 versus the line of adjacency of the two spinning members. Suction openings 3' 4' of the suction provisions 3, 4 are directed toward that triangular zone 36 from which the spun yarn is withdrawn. The fiber input location 5' of the fiber feed provision 5 is directed toward the surface of that spinning member 1 whose surface 32 moves in the direction of the first triangular zone 35.
