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 textile fibers 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, wherein the fibre-sorting device is arranged downstream of the supply device; at least one mechanical device adapted to generate a combing action from the clamping site to the free end of the fibre bundle, wherein the at least one mechanical device is associated with at least one of the first and second rollers; and a piecing arrangement adapted to remove the combed fibre bundles comprising a revolving element, wherein the piecing arrangement is adapted to release the clamping of the clamped ends of the combed fibre bundles after take-up of the free ends of the combed fibre bundles by the revolving element, and wherein the point in time of termination of the clamping forces on the fibre bundle is adjustable.
