Apparatus for separating opened fibre flocks from a transporting air stream

摘要

An apparatus for separating opened fibre flocks from a transporting air stream composed of one chute or of a plurality of consecutive chutes connected to a transporting duct. At least one air permeable separating wall guides transporting air into an exhaust duct located behind the separating wall. A driven take-off device which forms a fibre layer is arranged at the lower chute end. The take-off device comprises a take-off roll which is arranged facing the air permeable separating wall and leaving free a small cross-section, as the deposited fibres pass through. The exhaust duct extends at least into the zone of the smallest clearance between the take-off roll and the wall, and, the take-off roll is sealed with respect to the other wall.
