APPARATUS FOR THE FIBRE-SORTING OR FIBRE-SELECTION OF A FIBRE BUNDLE COMPRISING TEXTILE FIBRES, ESPECIALLY FOR COMBING

摘要

In an apparatus for the fibre-sorting or fibre-selection of a fibre bundle comprising textile fibres, especially for combing, which is supplied by means of supply means to a fibre-sorting device, especially a combing device, clamping devices are provided, which clamp the fibre bundle at a distance from its free end, and mechanical means are present, which 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, such as, for example, short fibres, neps, dust and the like from the free end. To enable the amount produced per hour (productivity) to be substantially increased in a simple manner and an improved combed sliver to be obtained, downstream of the supply means there is arranged at least two rotatably mounted rollers rotating rapidly without interruption, which is provided with clamping devices for the fibre bundles, which clamping devices are distributed spaced apart in the region of the rollers" peripheries, the supply means comprises a feed roller and a tray with a nip, and the retaining force in the nip optimally retains the short fibres completely or virtually completely in the nip during separation of the fibre bundle by clamping devices.
