Abstract:
A sliding frame, dual acting press comprising: a fixed frame member; a sliding frame member frictionally engaged with said fixed frame member; a mold adapted to contain material to be compressed; a first pressure exerting means operatively associated with said mold and adapted to move in relation to said mold and to thereby exert pressure on a first side of material in said mold; a second pressure exerting means operatively associated with said sliding frame member and operatively associated with said mold, and adapted to move in relation to said mold and to thereby exert pressure on a second side of said material in said mold opposite to said first side; wherein said pressure exerted on said material by said first pressure exerting means is in a direction that is substantially opposite to the direction through which said second pressure exerting mean is exerting pressure; and means to simultaneously apply substantially the same actuating force to both said first pressure exerting means and said sliding frame member; wherein said applied force is adapted to move said first pressure exerting means toward said material in said mold and is adapted to move said sliding frame member in a direction opposite to the direction of movement of said first pressure actuating member, whereby moving said second pressure exerting means in a direction substantially opposite to the direction of movement of said first pressure exerting means and toward said material in said mold; and thereby exerting substantially the same pressure on said material in said mold from substantially opposite directions.
