Zusammenfassung:Fiber separating device of an open-end spinning unit wherein the wall facing the fiber separating cylinder is provided with an impurity separating duct and with one or more air supply apertures. The air supply apertures are oriented symmetrically with respect to a plane substantially passing through the axis of the impurity separating duct and perpendicular to the axis of the fiber separating cylinder, the axes of said apertures including the same angles with the opposite walls of the impurity separating duct. The fiber separating device of the invention solves the problem of withdrawing impurities from fibrous materials supplied to the fiber separating device of open-end spinning unit, while reducing losses of the fibrous material.
