Abstract
The main drum diameter (D) of a card for short staple carding is reduced. The working width preferentially is enlarged. The main drum (50) can be made from fiber reinforced synthetic material. Notwithstanding its smaller diameter, the new main drum is operated at the same or a somewhat higher circumferential speed (in comparison to a conventional card).
