Abstract (en)
[origin: US4813103A] Apparatus for the removal by suction of fiber material on a movable bale opener which includes a suction channel with a fixed connection opening and a movable connection opening. The movable connection opening is part of a longitudinal slit in the suction channel, capable of being sealed by means of a covering band. In a space-saving arrangement which does not hinder the laying down of bales and makes it possible to remove the fiber material by suction in a pneumatically advantageous manner, the suction channel 3 is located in a plane above the bales B and the covering band 4, attached to the two ends of the longitudinal slit, 31 is held in sealing position by magnetic force.
