Abstract
A method and an apparatus for cleaning a carded sliver during a movement of the latter in its longitudinal direction is disclosed. The carded sliver is guided over at least one guide surface having perforations which leads to spreading and loosening of the sliver, and an air flow is generated through the perforated guide surface in order to remove loose contaminations and also dirt and dust particles present in the loosened sliver. The air flow emerging from the carded sliver and carrying dust and dirt particles is preferably drawn off.
