Abstract
Apparatus for making a fibrous web comprises a plurality of carding drums (3, 4, 5, 6), which closely succeed each other in the direction of travel of the feed web and rotate in the same sense. An air-permeable collecting surface is provided, on which the fibers of the feed web are deposited which fly from the carding drums (3, 4, 5, 6). Each carding drum (4, 5, 6) which succeeds another (3, 4, 5) in the direction of travel of the feed web constitutes a worker roller associated with the preceding carding drum. In order to increase the permissible speed of travel of the feed web, an additional worker roller (20) and a clearer roller (21) are associated with each carding drum (3, 4, 5, 6) on that side thereof which is remote from the collecting surface (7).
