Abstract
A band filter for the removal of foreign material particles from liquid baths, including a tub filled with liquid, guide rollers for a filter band arranged within the tub bath, the band being introduced into the tub from one side, guided with a spacing above the bottom of the tub and subsequently again conveyed out of the tub towards the top. The filter band being configured as a powered endless screen tissue band or as a filter fleece which is placed upon a support belt that is also driven in an endless manner. The filter fleece can in this case be unwound or reeled off a roller arranged outside of the tub, and a negative pressure chamber receiving the filtered liquid is arranged beneath the filter band. The faces of the filter band facing the bottom of the tub lie on a plurality of support faces extending transversely to the guidance direction of the filter band so as to be spaced from each other and parallel next to each other. Contact pressure rollers can be placed upon or lifted off the faces of the filter band facing away from the bottom, which contact pressure rollers are arranged in the tub.
