    (54) Sealing member for a filter press


    (57) The present invention relates to a sealing member preferably for sealing of the sides of the pressing zone of filter presses used in the pulp and paper industry. The sealing member according to the present invention solves the problems mentioned above because the sealing members (36, 38), made of practically permanent material which is ideal as to its friction properties relative to the wire surfaces, are constructed to form a single sealing member (30) together with the support members (32, 34), which sealing member (30) allows bending thereof conforming to the movements of the press wires, but prevents the tendency of the sealing member to bend, which tendency is caused by the pressure of pulp.
