Abstract

PURPOSE:To carry out continuous connection almost without swelling and increase flexibility by using continuous fancy veneers manufactured by butting finger processed sections of triangle tooth shape on both ends of a decorative timber veneer and reinforced with a non- woven tape as a base and laminating respective end faces of sliced veneers consisting of a plurality of layers coated with a bonding agent in a manner of crossing each other, pressurizing to manufacture an integrated laminate, grinding the surface and forming the specified thickness. CONSTITUTION:Finger processed sections 4, 4 of triangle shape are arranged in parallel in large number on both ends of decorative timber and fancy veneers 1, 1 of given width, and said processed sections 4, 4 are butted and crossed each other. A non-woven tape 5 is applied on the surfaces 2 of respective butted sections by means of a bonding agent for reinforcement, and then formed into a continuous material of spiral roll. Said continuous decorative timber fancy veneer is unwound to manufacture bases 7, and veneers 12 of required numbers with their inner faces coated with the bonding agent 11 are laminated successively on the inner faces 3 of the bases 7 in a manner of crossing each other, and then the fancy veneers 12 laminated with the bases 7 are press pressurized to manufacture an integrated laminate 13 with flexibility. Its surfaces 2 and 3 are ground by a sander, and the reinforced non-woven tape 5 on the surfaces of bases are ground and removed to manufacture a laminated continuous fancy veneer 51 of approximately 2.0-4.0 mm thickness.
