[origin: US5839166A] PCT No. PCT/EP95/03088 Sec. 371 Date Feb. 27, 1997 Sec. 102(e) Date Feb. 27, 1997 PCT Filed Aug. 3, 1995 PCT Pub. No. WO96/06964 PCT Pub. Date Mar. 7, 1996A card apparatus for producing an aerodynamically formed fibrous web (4), includes a fiber feed means (6), a main cylinder (8) rotating at high speed and a shaft (10) arranged at main cylinder (8), the shaft transporting thrown-off fibers in an airflow (12) to an air-permeable web transport means (14) and disposing said fibers on said web transport means (14) in the form of a fibrous web (4). In this apparatus the main cylinder (8) throws off said fibers at a first location (22) of shaft (10) onto a second cylinder (20) rotating at high speed in opposite sense to main cylinder (8) and generating a random orientation of said fibers on cylinder (20), and the second cylinder (20) throws off said fibers into airflow (12) at a second location (24) of shaft (10).
