Abstract

Abstract A press for compressing resilient material having a frame, a stationary bottom press plate mounted in the frame, and a piston cylinder combination on the frame for moving a movable press plate between a datum position and a second position more closely adjacent the bottom plate and spaced therefrom. The above plates have adjacent, generally planar pressing surfaces with said surfaces diverging at least a slight amount in the direction that compressed product is to be moved in being ejected from between the plates when the movable plate is in its second position. There is provided a spout through which the compressed product is moved by a power operated pusher head that moves between the plates when the movable plate is in its second position. The pusher head has an extensible portion to move vertically as the presser head moves horizontally relative the tapered press plate.
