ABSTRACT:
A filter-plate assembly for a filter press has a substantially rigid support plate against which bears a filter plate. This filter plate is integrally formed of elastically deformable material and has an annular outer frame which lies against the support plate and defines a frame plane. A generally planar and elastically deformable central panel lies in a panel plane and is displaceable relative to the frame between a normal position to one side of the frame plane and lying against the support plate and a pressing position to the other side of the frame plane. This panel is formed with an array of bosses projecting away from the support plate. An annular web has an outer periphery connected to the frame at the frame plate and an inner periphery connected to the panel at the panel plane. This web is relatively thin and elastically deformable like the central panel and has a surface area which is greater than the surface area of the projection of the web on the frame plane.
