In a double band press apparatus having an upper and lower endless press belt, each rotatively engaged over a pair of drums defining a reaction zone between opposed outer sides thereof, pressure chambers are defined on the inner sides of each of the press belts for applying a fluid pressure to material passed through the reaction zone. The pressure chambers are bound on one side by pressure plates having a sealing structure extending circumferentially about the pressure chambers, the sealing structure consisting of a continuous sealing member encircling the pressure chamber and applied in sliding engagement with the inner side of the press belts, a one-piece support plate upon which the sealing members are mounted and a continuous resilient boot which extends coextensively with the sealing members and which applies a resilient force pressing the sealing members against the press belts.
