Abstract:
1. A method of manufacturing glued laminated wood which is made of a number of wood sheets, each having a predetermined length, width and thickness, and having a first surface and a second surface, laminated together by hot pressing with a thermosetting adhesive into a continuous length of multiple-layered board of said glued laminated wood,comprising the steps of: providing an initial base material having an end from which said continuous length of the glued laminated wood board is formed extending in its lengthwise direction, said end of the initial base material being shaped in the form of a flight of steps including a series of alternate horizontal surfaces each having a lengthwise dimension smaller than the length of each wood sheet and a series of crossing surfaces formed at an angle with respect to said respective horizontal surfaces, any two adjacent horizontal surfaces thereof across the thickness of the initial base material being spaced at an interval substantially the same as the thickness of the wood sheet; feeding wood sheets to be used in said glued laminated wood board adjacent to said end of the initial base material with one end thereof being disposed in facing relation to the respective crossing surfaces so that the thus fed wood sheets are laminated in said glued laminated wood board with opposite ends thereof remote from the initial base material being disposed in a staggered array which is similar to said form of flight of steps; and hot pressing at least one of the thus fed wood sheets for lamination by a hot press having a pair of plates, at least one of which is heated, each having an effective pressing area capable of entirely covering either one of said first and second surfaces of any of said wood sheets, said at least one of said wood sheets being placed and maintained for a predetermined length of time at a position where the first surface of said at least one of said wood sheets is kept to be pressed in its entirety by one of said plates while the second surface of said at least one of said wood sheets is supported in its entirety by the other plate with a layer of thermosetting adhesive being interposed between surfaces of said wood sheets.
