ABSTRACT:
In the case of an open-end spinning arrangement, a spinning rotor is arranged in a rotor housing, to which a vacuum of at least 500 mm water column is applied. A fibre feed channel, beginning at an opening roller with an entry opening, is directed with an outlet opening at a sliding wall of the spinning rotor. The fibre feed channel bends slightly in the direction towards a fibre collecting groove of the spinning rotor. The cross sectional area of the outlet opening of the fibre feed channel measures at least 19 mm.sup.2 and amounts to at least 30% of the cross sectional area of the entry opening. As a result of the bend in the fibre feed channel, the fibres are collected together in a fibre bundle on a longitudinal side of the fibre feed channel. The fibre bundle occupies only a part area of the outlet opening when leaving the fibre feed channel and is fed with high precision onto the sliding wall. The outlet opening can thus have larger dimensions without this leading to inaccurate feeding of the fibres. The outlet opening possesses dimensions that permit a large volume of air to flow at high speed from the opening roller through the fibre feed channel. Fly accumulation in the area of the opening roller is thus avoided.
