    Patent number: 3935049
    Abstract: Laminates are prepared from rigid panels or sheets (e.g. gypsum board or plywood) and resin-saturated paper by a unidirectional pressure process which simultaneously bonds the paper to one of the broad flat sides of the panel or sheet and to one or more of the adjacent thin sides of the panel or sheet which intersect the broad side. The resulting laminates are useful in the construction of walls and furniture.
