(57) 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.
