Abstract:
A method of operating a belt press, comprising:a) disposing a first press surface belonging to a first platen substantially parallel to and opposing a second press surface belonging to a second platen; said first platen having a longitudinal axis running between first and second end portions and disposed substantially parallel to said first press surface;b) disposing belt material between said press surfaces;c) restricting the movement of said first press surface relative to said second press surface in a direction generally normal to said first press surface; andd) thereafter, heating said first platen and, while heating, resisting the thermal expansion of said first platen generally along said longitudinal axis thereof by tensioning at least one limit member so as to cause said first press surface to press towards said second press surface between said first and second end portions, and thereby apply substantial compressive force to said belt material.
