ABSTRACT:
An expandable bag is supported on a base and is associated with first and second platen means. The first platen is movable in a pressing operation relative to the second platen by expansion and contraction of the bag. The second platen is movable relative to the first platen in a plane parallel with the pressing surfaces of the platen for loading articles onto and unloading them from the first platen. The second platen has backup support for pressing functions by the frame of the press. The second platen is carried on a wheeled support for its movement in a plane parallel with the pressing surfaces and is associated with shock absorbers at the limits of its travel. Controls are provided for sequence functioning of the expandable bag and the second platen. The press has an opening at the top adjacent the front which is opened and closed by movement of the second platen.
