Apparatus for open-end spinning textile yarns comprises fibre feed means, spinning means to receive fibres from the fibre feed means and to spin them into a tail end of yarn for continuous withdrawal of yarn from the spinning means, and yarn withdrawal means to withdraw the yarn along a yarn withdrawal axis to a yarn delivery aperture of the spinning means and to form the yarn into a package. The yarn withdrawal means comprises a package forming assembly and a yarn engaging means. The package forming assembly is operative to form a package of the yarn and has yarn distributing guide means to distribute the yarn on the package. The yarn engaging means is operative to engage the yarn in its passage between the yarn delivery aperture and the yarn distributing guide means. The yarn engaging means and the yarn distributing guide means are mounted on opposite sides of a plane containing the yarn withdrawal axis in such disposition that the distance travelled by the yarn from the yarn engaging means to the yarn distributing guide means is greater than the distance from the yarn delivery aperture to the yarn distributing guide means.
Apparatus for open-end spinning textile yarns, comprising a longitudinally extending machine frame, a plurality of spinning units mounted at spaced intervals along said machine frame, each said spinning unit including fibre feed means and spinning means for receiving fibres from the fibre feed means and spinning them into a tail end of yarn for continuously withdrawal of yarn from the spinning means, yarn withdrawal means for withdrawing the yarn along a yarn withdrawal axis to a yarn delivery aperture of the spinning means and forming the yarn into a package, said yarn withdrawal means comprising a package forming assembly for forming a package of the yarn and having yarn distributing means for distributing the yarn on the package and yarn engaging means to engage the yarn in its passage between the yarn delivering aperture and the yarn distributing means, wherein the yarn engaging means and the yarn distributing guide means are arranged on opposite sides of the spinning unit and wherein the distance travelled by the yarn from the yarn engaging means to the yarn distributing means is greater than the distance from the yarn delivery aperture to the yarn distributing guide means.
