Abstract
A dual press having hydraulic units which are controlled to regulate the pressure exerted on material being treated. A control system includes sensing means along the path of materials passing to the press and sensing means along the path of materials passing from the press. Thus, sensing means control the hydraulic units and regulate the pressure so as to maintain a predetermined maximum pressure when a continuous supply of material is passing through the press. The pressure is reduced or removed completely when the supply of material is decreased or interrupted.
