Abstract
In an apparatus for the fiber-sorting or fiber-selection a fiber bundle which is supplied by means of a supply device to a fiber-sorting device in which clamping devices are provided which clamp the fiber bundle at a distance from its free end, and in which a mechanical device is present which generates a combing action, for removal of the combed fiber material a revolving element is present. To enable the amount produced per hour (productivity) to be substantially increased in a simple manner and to permit a reliable removal and piecing at high production speed, downstream of the supply device there are arranged at least two rotatably mounted rollers with clamping devices for the fiber, which clamping devices are distributed around the periphery of at least one of the rollers and the device for generating a combing action is associated with a said roller, wherein after take-up of the free regions of the combed fiber bundles by the revolving element, the clamping of the ends of the combed fiber bundles is terminated.
