Abstract
A method and apparatus of manufacturing glued laminated wood such as laminated veneer lumber (LVL) are 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 of the glued laminated wood wherein wood sheets in each layer of the multiple-layered board are arranged in a staggered relation in the lengthwise direction of the board to wood sheets in an adjacent layer. The hot press has a pair of heating plates arranged substantially in facing relation to each other and an auxiliary heating plate disposed adjacent to one end of each heating plate. The auxiliary heating plate is adapted to press part of wood sheet which extends out beyond the above end of the heating plate.
