Abstract
A fibrous feed web is delivered by a feeder to tooth-carrying carding drums, which rotate at a surface velocity which causes the fibers to flow off under centrifugal force to fly onto a continuously moving, air-permeable collecting surface, which is subjected to suction. In order to make a uniform fibrous web with simple structural means even at a high throughput, the carding drums are closely spaced apart in the direction of movement of the collecting surface and each carding drum which succeeds another carding drum in the direction of movement of the collecting surface constitutes a working roller for such preceding carding drum.
