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.
Claims6
A textile card for producing fibrous webs and random webs of textile fibers comprising a series of cylinders fitted with metallic wire which rotate relative to each other in a predetermined sense, and a plurality of worker rollers coordinated with said cylinders, a fiber intake and, at least one take-off roller, said worker rollers including a trough shaped cover which includes trough-shaped plates, and said cover containing an opening for regulating the air current between said rollers and said cover, characterized in that said trough-shaped cover of said worker rollers is formed of a plurality of trough sections arranged in spaced series relationship, and means for opening said trough sections to provide a desired air flow around said cylinder and rollers.
