An open-ended textile spinning rotor has a cover over a reduced-pressure chamber with a fibre outlet to a fibre jet to a concave transitional surface. A 2 mm gap remains between the concave surface and cap. No more than half the outlet (31) is presented to the cylindrical mantle (50), the other half being is over the concave transitional surface (60). - The outlet (14) rim (33) gap (a) furthest from the end face (42) is at least 0.5 - 3 mm greater than the gap (b) to the neighboring wall zone (32). |
