Abstract: In a card, to avoid passage of fibers or fiber flocks over the edge of clothing into a gap, a covering band is pressed against an internal surface of the fiber-guiding roll or cylinder and a surface lying opposite the fiber-guiding roll. The covering band covers the gap between the fiber-guiding roll and a side wall portion. Two forwarding grooves, lying opposite one another in the gap and having transport surfaces lying opposite one another in crossed fashion, return fiber flocks which may possibly pass into the gap to the upper surface. A forwarding pin is set into the roll surface 7 of the fiber-guiding roll outside the edge of the clothing at such a inclination that fibers or fiber flocks which can pass into this region are transported by such pin towards pointed clothing of card flats.
