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, 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 device generates a suction air current that acts on the fibre bundles during transfer before clamping by the clamping devices.
