Apparatus for holding hollow wall panels while they are filled with foamed plastic

Abstract

Apparatus for holding hollow wall panels while they are filled with foamed plastic having a base, a lower platen, an upper platen, and a plurality of inflatable hoses. The base has a top pressure surface upon which the inflatable hoses are positioned. As fluid under pressure is released into the inflatable hoses, the upper surface of the hoses contact the bottom pressure surface of the lower platen to lift the lower platen upwardly. The hollow wall panels are supported by a plurality of longitudinally spaced roller support brackets that extend downwardly from the opposite sides of the upper platen. As the inflatable hoses are pressurized, the upward travel of the lower platen will cause its top pressure surface to contact the bottom of the hollow wall panels and hold them in rigid engagement against the bottom pressure surface of the upper platen. When the hollow wall panel is thus positioned, it is filled with foamed plastic.
