    (54) Sealing apparatus for a filter press


    (57) The present invention relates to a sealing apparatus pre­ferably for sealing of the sides of the pressing zone of filter presses used in the pulp and paper industry.
    The sealing appar­atus has been cast into a unit, which comprises a back (11), lips (13 and 14) with a space (15) therebetween and a support member (12) in the depth direction of the space, said support member allowing the sealing apparatus to bend in conformance with the movements of the press wires but elimin­ating the tendency of the sealing apparatus to bend under the press of the pulp.
