ABSTRACT:
A card for producing fibrous webs or random webs of textile fibers comprises a plurality of cylinders in series with metallic wire. The cylinders rotate in a predetermined mutual sense to which worker rolls are coordinated. The cylinders and workers are covered by trough-shaped plates. The trough-shaped cover of the cylinders or workers (7, 8, 9) is formed of a plurality of trough sections (20a, 20b, 20c, 20d, 20e) which are arranged in close succession. The trough sections are adapted to be adjustable and to be opened respectively. By this means, a control of the optimum air amount at the rollers may be achieved uniformly over the working width.
