Abstract:
1. 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 rotate rapidly without interruption during use; clamping devices distributed about the periphery of at least one of said first and 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 bundle; a supply device adapted to supply the fibre bundle to the fibre-sorting device, the supply device comprising a feed unit including a feed roller and at least one feed tray, the feed roller and at least one feed tray defining a nip therebetween, wherein the nip is adapted to generate a retaining force sufficient to completely or substantially completely retain short fibres in the fibre bundle during separation of the fibre bundle by the clamping devices; and at least one mechanical combing device that generates 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 distance of the feed unit from the first roller is adjustable.
