Abstract (en)

[origin: WO2006079426A1] A sensor system (3, 3') for detecting foreign matters and a separation device (4) provided with at least one compressed air nozzle (5) which is perpendicular to a pneumatic fibre conveying conduit are successively mounted in a direction of conveyance (a), wherein said fibre conveying conduit is provided with a removing opening (6) arranged in front of the compressed air nozzle. Contrary to state of the art of actual methods and devices, the foreign matters are not removed to a substantially pressure-tight separation container. According to said invention, the removing opening (6) is connected to a derivation (7, 10) in which a permanent airflow (d, e) for transporting separated foreign matters away is maintained.
