Abstract

PURPOSE:To obtain flexible laminated fancy veneer in continuous form by a method wherein both ends of precious wood veneers, which are subjected to hot press and cold press, are abutted against each other under the condition being finger cut and non-woven fabric tape is attached to the front surface of abutted veneers and, to its rear surface, sliced veneers, which are subjected to similar pressing treatments, are laminated under the condition that the positions of their respective ends are staggered, and, after being press, both the sides of the resultant laminate are ground. CONSTITUTION:To both ends of precious wood sliced veneers 1, which has been subjected to heating for softening with a hot press and quenched for releasing strain with a cold press and has the thickness of about 0.2-0.6mm, finger cut 4 consisting of a large number of triangular tooth forms in parallel is applied. By abutting said finger cut parts against each other and adhering non-woven fabric tape 5 to its front surface 2 for reinforcement, the veneer 1 is wound in a spiral roll. By unwinding said roll, the veneer is employed as base 7. Necessary number of sliced veneers 12, on the inner surface of each of which adhesive 11 is applied and each of which has the thickness of 0.5-1.0mm, are laminated onto the inner surface 3 of the base 7 under the condition that the edge faces 12a of the sliced veneers 12 are staggered so as to obtain laminated 13 by pressurizing with a press. Since the resultant laminate has projections 10, the front surface 2 of the base 7 and the inner surface 3 of the laminate are ground so as to obtain uniform thickness and, at the same time, the non-woven fabric tapes 5 are removed by grinding so as to obtain the thickness of about 2.0-4.0mm.
