Abstract
An apparatus for eliminating metallic contaminations from a fibre transporting duct in spinning preparation, wherein an air stream transports fibre flocks through the duct. At a branching point of the fibre transporting duct leading to a waste duct there is pivotably arranged deflecting means operatively connected with and activated by a drive mechanism. The deflecting means are activated in response to the passage of a metallic object or other metallic contaminations through a section of the fibre transporting duct surrounded by a metal detector arranged upstream of the branching point, by means of a control device connected with a power source and the drive mechanism. Within a short time the deflecting means can be shifted from an idle or ineffectual position, where the transporting duct is open and the waste duct is maintained closed, into a working position, in which the transporting duct is closed and the waste duct is maintained open.
