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:

• at least one fibre sorting device comprising at least a first high-speed roller and at least two second high-speed rollers that rotate rapidly without interruption during use;
• clamping devices distributed about the periphery of the first roller and the second rollers, each clamping device adapted to clamp a bundle of the textile fibres at a clamping site located at a distance from a free end of the fibre bundle;
• at least one supply device adapted to supply the fibre bundle to the fibre-sorting device;
• at least one take-off device adapted to remove the sorted fibre material from the fibre-sorting device, the take-off device comprising a take-off roller associated with each of the at least two second high-speed rollers;
• at least one mechanical combing device adapted to comb the fibre bundle from the clamping site to the free end in order to loosen and remove non-clamped constituents.
