ABSTRACT:
A separating device comprises an endless carrier belt which supports a filter belt. Suction boxes for drawing off filtrate are placed on the side of the carrier belt. The carrier belt protrudes laterally into the continuous slot of the vacuum box. In a large separating installation with long carrier belts and filter belts lateral displacements of the carrier belt occur during operation, whereby sealing becomes a problem. These problems are resolved according to the invention in that the suction box has a sealing member connecting onto the side edge of the carrier belt and this sealing member is displaceable laterally.
