ABSTRACT:
Located in the path of transport for the fibres in an apparatus for supplying separated fibres to a spinning rotor of an open-end spinning unit is a removal opening, from which the impurities contained in the fibrous material are removed. In order to be able to provide mechanical conveying means, which do not disturb the pneumatic fibre transport, behind the removal opening and at a relatively great distance therefrom, the removal opening is designed in such a manner that it serves as a type of air buffer and impairs the formation of a strong air flow.
