<p>An apparatus for eliminating metallic contaminations from a fibre transporting duct (1) in spinning preparation, wherein an air stream transports fibre flocks through the duct. At a branching point (2) of the fibre transporting duct (1) leading to a waste duct (3) there is pivotably arranged deflecting means (7, 7) operatively connected with and activated by a drive mechanism (13). The deflecting means (13) are activated in response to the passage of a metallic object through a section of the fibre transporting duct surrounded by a metal detector (14) arranged upstream of the branching point (2), by means of a control device (17) connected with a power source (19) and the drive mechanism (13). Within a short time the deflecting means (7, 7) can be shifted from an idle position, where the transporting duct (1) is open and the waste duct (3) is maintained closed, into a working position, in which the transporting duct is closed and the waste duct is maintained open. </p> |
