摘要： A sliver feeding device for an open-end spinning frame, comprising a sliver draw-in roller and a sliver feed trough pivotable about a supporting shaft for movement toward and away from the draw-in roller. The draw-in roller has an annular sliver conveying collar which defines a sliver nip between the collar and the feed trough, and the feed trough has opposed laterally spaced bars for receiving the collar therebetween to guide the sliver at the nip. The draw-in roller is rotatably supported so as to permit a predetermined amount of axial movement of the collar between the guide bars of the feed trough. Similarly, a predetermined amount of axial movement of the feed trough is permitted on the supporting shaft. The collar has axial end faces each comprising a respective cleaning device. The guide bars of the feed trough have inwardly facing bevels which, in connection with the axial play of the feed trough on the supporting shaft, assure automatic pivoting of the feed trough into its operating position.

摘要： A fiber opening, fiber feeding and yarn withdrawing unit for a spinning station of an open end rotor spinning machine, in which a projection of the fiber feed conduit extends into the rotor behind the fiber slide wall at a close spacing thereto and to an extent greater than the diametrical extent of the open end of the rotor. The components of the unit are mounted on a unit housing that pivots about an axis transverse to the axis of rotation of the rotor and spaced from the plane of the collection groove of the rotor to the side opposite the rotor open end and also spaced from a plane generally perpendicular to and at the rotor open end of the portion of the fiber slide wall adjacent the fiber feed conduit end, for pivoting of the projection into and out of the rotor without interference therewith. The fiber feed conduit opening in the projection wall is enlarged from the interior of the conduit in the direction of rotation of the rotor and the spacing between the projection and the fiber slide wall of the rotor increases along the enlarged conduit opening.

摘要： 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easily observed, the feeding in of fibers is provided at a rear triangular zone 35 whereas the twisted spun yarn 6 is withdrawn from the other triangular zone 36 in parallel to the plane 34 of the closest distance between the two spinning members 1, 2.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.
