Abstract: To make a bulky nonwoven web of low density and high uniformity with an apparatus comprising a toothed opening roller rotatable at a sufficient speed to throw off a stream of fibers centrifugally and deposit them on a revolving air-permeable collecting surface member which has a fiber-receiving portion and a suction box having an opening underneath this portion, a guide roller is spaced vertically from the fiber-receiving portion. The guide roller is rotated in a direction opposite to that of the opening roller and has a leading peripheral surface portion facing the opening roller and projecting into the stream of fibers to deflect a part of the fibers, and a trailing peripheral portion constituting a suction zone facing the fiber-receiving portion. A guide wall in the suction box opening controls the air stream sucked through the fiber-receiving portion in the direction of the movement of the collecting surface member.

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.
