摘要： A method and apparatus for joining two pieces of wood veneer with square cut edges by a lap joint with a pre-determined thickness not greater than the thickness of a single piece of veneer. The lap joint is formed in a press which may have heated plates for pressing the overlapping portions of the veneer pieces together. The press is provided with adjustable stops for limiting the spacing between the platens in the final pressed position to provide the lap joint with the pre-determined thickness. The lap joint is bonded by glue provided on the surface of at least one of the overlapping portions of the two veneer pieces. The lap joint is heated to an elevated temperature above the lignin softening temperature of the veneer during pressing to enable thermoplastic flow of the wood veneer which produces a lap joint of greater strength. The two platens are formed with anvil surfaces including flat middle surfaces which are parallel, and side surfaces on opposite sides of each middle surface which slope away from each other and which are joined to the middle surface by curved transition portions to avoid cutting the veneer and produce a stronger lap joint.

摘要： Methods for forming structural beams and the beams resulting from such methods are disclosed. The disclosed methods compress and adhesively bond wood strands into beams. A beam formed from any one of the disclosed methods may, if desired, have any one of several disclosed shapes, strand configurations, or strand densities.

摘要翻译： 一种通过搭接接头将两片木材单板与方形切割边缘连接的方法和装置，其预定厚度不大于单片胶合板的厚度。 搭接接头形成在压力机中，压力机可以具有用于将单板的重叠部分压在一起的加热板。 压力机设置有可调节的止挡件，用于限制压板在最终压制位置之间的间隔，以使搭接接头具有预定的厚度。 搭接接头通过设置在两个单板的至少一个重叠部分的表面上的胶粘结。 在挤压过程中将搭接接头加热至高于木质素软化温度的高温，以使得能够产生具有更大强度的搭接接头的木材单板的热塑性流动。 两个压板形成有包括平行的平坦的中间表面的平面中间表面的砧座表面和在每个中间表面的相对侧上的侧表面，其彼此远离并且通过弯曲的过渡部分接合到中间表面，以避免切割单板， 产生更强的搭接。
