Abstract
The invention relates to a method of gluing veneers to form LVL and plywood boards from veneers laid one over the other in several layers by curing the adhesive placed between the single layers in a heated press. The invention consists in the fact that the gluing and pressing of the outer layers of a veneer pack to form LVL and plywood boards is performed by high-temperature adhesive and the inner layers by low-temperature adhesive, so that the amount of heat to be put into the veneer pack decreases from the outside in.
