Abstract
A method for preparing a laminate including pressing a heater against the upper and lower surfaces of a veneer during which an inner portion of the veneer in the thickness direction is dried to the smallest extend then the surfaces so that a water content of the inner portion is kept higher than that of the surfaces, dividing the veneer in terms of its thickness into two counter veneers, placing a ligneous board between the counter veneers using an adhesive so that the surfaces resulting from the diving are disposed as outer surfaces, and pressing a heater against the outer surfaces to effect bonding of the counter veneers and the ligneous board. The period of time for pressing the heater against the upper and lower surfaces of the veneer is such that the surfaces and a region in a vicinity thereof, against which the heaters have been pressed, are dried to a water content of between about 5% and about 20% while the inner portion of the veneer in the thickness direction is dried to a water content higher than the fiber saturation point at which contraction begins.
