Abstract
Method for forming a laminate and a product formed therefrom. A thin layer of oil is applied to a facing surface of at least one of a plurality of adjacent sheets and a wax is applied along the longitudinal edges of a facing surface of at least one of the sheets. The sheets are combined into a laminate by being passed between a pair of rollers which apply sufficient pressure to remove excess oil from between the facing surfaces and to spread the wax thereby forming a continuous seal along the longitudinal edges of the laminate. Air between the facing surfaces is displaced by the oil and the wax forms the seal to prevent reentry of the air and seepage of the oil along the longitudinal edges of the laminate. The laminate is tightly held together to permit handling or fabrication without delamination.
