Abstract
In a high production card, a taker-in undercasing without slits or apertures is disposed beneath a taker-in roller of a card and a suction device is disposed above the taker-in roller. A taker-in cover is mounted atop the taker-in roller and defines therebetween a sealed space in communication with the suction device, which suction device controls the air pressure in said space between the taker-in roller and the taker-in undercasing, so that impurities such as trash are mainly removed from the supplied fibers at a free space below the taker-in roller formed at a position upstream from the taker-in undercasing, and short fibers are separated from successive fibers mainly by the action of the suction device.
