Abstract
A method and an apparatus of wood pressing usable in manufacturing glued laminated wood such as laminated veneer lumber (LVL) using a number of wood veneer sheets are disclosed. A hot press used for wood pressing includes a pair of heating plates which are disposed one above the other and have pressing surfaces facing each other. The paired heating plates are both movable toward and away from each other. In operation, firstly one of the heating plates is moved toward the other heating plate to a position where the pressing surface of the one heating plate is spaced from a surface to which a veneer sheet is to be glued by a distance corresponding to the thickness of the veneer sheet. Then, the other heating plate is moved toward the one heating plate until a desired pressure is produced pressing.
