A method of manufacturing glued laminated wood such as laminated veneer lumber (LVL) is disclosed. The glued laminated wood is made of a number of wood sheets such as veneer sheets which are laminated together by a hot press with a thermosetting adhesive into a continuous length of multiple-layered board wherein the end joints of the wood sheets are disposed in a staggered array. There is provided an initial base material having an end which is shaped in the form of a flight of steps including a series of alternate horizontal surface having a lengthwise dimension smaller than the length of the wood sheet and a vertical surface having a height corresponding to the wood sheet thickness, and the glued laminated wood board is formed extending from the end of such initial base material. The hot press includes a pair of heat plates each having an effective pressing area capable of covering the entire surface of the wood sheet. In hot pressing a wood sheet having on one surface thereof coated with adhesive, a board of the glued laminated wood in progress is placed and maintained for a predetermined length of time at a position where the entire top surface of the wood sheet is kept to be pressed from the top by one of the plates while the entire lower surface of the wood sheet is supported from the bottom by the other plate.
