Abstract
In a feed comb arrangement for a combing machine comprising an intermittently driven pair of feed rollers preceding the feed comb arrangement in the transport direction of the fiber web to be combed and a take-down arrangement, in particular in the form of take-down rollers, following the feed comb arrangement, it is provided for the purpose of increasing smoothness of running, of avoiding accumulations of impurities and of attaining an effective transport that the feed comb arrangement is formed by a plurality of fallers, which are intermittently driven in synchronization with the combing operation and which are covered with needles or saw-toothed stamped elements, respectively, which fallers extend on their two outer ends into closed guideways in such a manner, that during part of the route of rotation the needles or saw-toothed points, respectively, engage with the fiber web and on the other hand the needles or saw-toothed points, respectively, upwardly leave the fiber web after having traveled a transport motion.
