ABSTRACT:
For use in the making of slivers from a lap, an apparatus is proposed which comprises a plurality of tooth-carrying carding drums (3, 4, 5, 6), which succeed each other in the direction of travel of the lap. Each carding drum (4, 5, 6) which succeeds another constitutes a worker roller for cooperating with the preceding carding drum (3, 4, 5). The fibers which fly from the carding drums (3, 4, 5 and 6) into ejection ducts (10) are deposited in the form of strips on a collecting surface (7), to which a vacuum is applied only in zones.
