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 the first roller and the second roller, 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; 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; a take-off device comprising at least one sliver-forming element; and a drafting device located downstream of the at least one sliver-forming element; wherein the at least one sliver-forming element is located between the take-off device and the drafting device, and the at least one sliver-forming element is adapted to form the combed fibre material into a fibre structure having a cross section defining a width and a height, wherein the width is greater than the height.
