Abstract
The separation of impurities through an opening in the casing of a rotating roller or drum is increased by guide grooves or guide gaps in the casing. The guide grooves or guide gaps extend in the direction of movement of the conveyed fibers and open out into the separating opening. The guide grooves may be formed directly in the casing in the surface facing the rotating roller or drum or may be formed by separate elements which are mounted on the casing and extend into the separating opening.
