Abstract

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.
