摘要

In an apparatus intended to be cleaned of the fibrous material, a first roller (3b), which is designed to support or transport a sheet of fibers, is associated with a second roller (18) and a third roller (19). The rollers (3b, 18, 19) have a lining with the hands or the teeth which are inclined at an acute angle (angle before) in the direction of rotation, and in the zone of the transition of the fibers of the first roller (3b) towards the second roller (18), the hands or the teeth are inclined in different directions, and the speed of the second roller (18) is small compared with the speed of the first roller (3b). In order to improve the degree of cleaning, the front corner of the teeth (182) of the second roller (18) is approximately 10 degreeà 50 degreeet the spaces of the packing are large in order to obtain a filling volume is higher for the fibers.
