DEVICE FOR REMOVING A LAYRE OF MATTED FIBERS ON A FILTER DRUM ROTATABLE IN A FILTER HOUSING

摘要

A filter drum is screened off at the matted fibers take-off position on its interior face via a sealing membrane which is pressed by support sheets and a tightening element against the interior face. The drum is positioned within a housing whose interior is subjected to a suction force and is sealed off from the atmosphere by lip seals. A gap between a compression roll and a take-off roll is tightly filled by the compressed layer of matted fibers so that the entry of leakage air is prevented.
