Abstract

Machine makes plates and tubes, using simple or double-action hydraulic or pneumatic jacks. The feed pressure is controlled in known way be an electric valve. The jack pressure is controlled by comparing two electric currents proportional respectively to the preset value and to the effective value of linear pressure, so that the pressure's preset value can be adjusted at will for several thicknesses of rolled paste, and the line joining the points of the diagram of pressure vs. thickness can be straight or curved.
