ABSTRACT:
A press is provided of the type used in compressing refractory material at high pressures in the manufacture of bricks and the like. The press includes a bed, columns supported by the bed, and a mold table slidably supported on the columns, the mold table including a central aperture housing a removable mold. The press further includes at least one plunger extending upwardly into the mold cavity of the mold. The press also includes a pallet for supporting the plunger, the pallet being releasably attached by alignment pins to the press bed and being supported for slidable movement on the upper surface of the press bed by a plurality of inflatable air bags located between the upper surface of the press bed and the pallet, the air bags each including at least one aperture in the bottom wall of the air bag. Air can be forced into the air bags to cause inflation of the air bags and can escape through the aperture in the bottom wall to form a fluid cushion between the pallet and the upper surface of the press bed.
