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, the apparatus comprising:

• a fibre-sorting device comprising at least a first roller and a second roller that, in use, rotate rapidly without interruption, and clamping devices distributed spaced apart about a periphery of at least one of the first and second rollers, each clamping device adapted to clamp a bundle of the textile fibers at a distance from a free end of the bundle;
• a supply device adapted to supply the fibre bundle to the fibre-sorting device;
• and
• at least one mechanical device adapted to generate a combing action from the clamping site to the free end of the fibre bundle in order to loosen and remove non-clamped constituents, wherein the mechanical device is associated with at least one of the first and second rollers;
• and
• wherein the fibre-sorting device further comprises at least one suction device associated with the clamping devices in a region of transfer of the fibre bundles from the supply device to the first roller, and/or in a region of transfer of the fibre bundles from the first roller to the second roller, wherein the suction air current influences the alignment and movement of the fibre bundles to be supplied and taken up.
