ABSTRACT:
Plywood and other glued, laminated assemblies are made by spreading a liquid foamed glue on a surface of a first lamina. A second lamina is superimposed and, while the glue is in a fluid condition, the resulting assembly is prepressed under pressure sufficient to spread the glue and to wet and unite the opposed faces of the laminae. This forms a flat, self-sustaining intermediate laminate which thereafter may be pressed further to develop the glue bond between the laminae.
