The present invention is directed to a method of holding a veneer sheet which has been dried to a moisture content lower than the fiber saturation point and also heated to a temperature higher than an ambient temperature of an environment where the veneer sheet is held. The veneer sheet is bent in such way that at least a part of the veneer sheet in the longitudinal section thereof along the grain direction is curved and the same veneer sheet in any transverse section thereof perpendicular to the grain direction is substantially straight. The veneer sheet held bent is held for a predetermined period of time.

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.

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.

Electric connecting method and apparatus

According to a method of transferring a sheet through a working apparatus, a first sheet is moved by feed rolls partially into a working area of the working apparatus, which is followed by moving a second sheet by the same feed rolls to allow the leading end of the second sheet to be brought into abutment with the trailing end of its preceding first sheet and then to push the first sheet to a predetermined position within the working area. After the first sheet is thus placed and the second sheet is moved back out of the working area, the apparatus is operated to work the first sheet, for example, by pressing. The second sheet is moved forward into abutment with the trailing end of the worked first sheet and moved further while pushing the first sheet toward delivery rolls of the apparatus, which then removes the first sheet out of the working area of the apparatus. Such steps of operation is repeated to transfer a series of sheets successively through the working apparatus.
