Apparatus for the fibre-sorting or fibre-selection of a fibre bundle comprising textile fibres, especially for combing

An apparatus for the fibre-sorting or fibre-selection of a fibre bundle comprising textile fibres having:

• a fibre-sorting device;
• a supply device for supplying the fibre bundle to the fibre-sorting device;
• and
• at least one mechanical device for generating a combing action in order to loosen and remove non-clamped constituents from the fibre bundle;
• wherein the fibre-sorting device comprises, arranged downstream of the supply device, at least two rotatably mounted rollers that, in use, rotate rapidly without interruption, each of said at least two rollers having clamping elements distributed spaced apart in the region of their periphery and co-operating with one or more counter-elements, wherein the counter-elements in the case of the first roller are opposite the periphery of the roller and the counter-elements in the case of the second roller are arranged on or in the roller, wherein on the first roller a suction air current acts on the fibre bundle, which suction air current is capable of holding the fibre bundle on the first roller.
