板の表面に出現して集成単板を不良品としていた。[Background technology] Traditionally, raw material veneers used in the production of laminated veneers are made by processing relatively low-grade logs into thin veneers (rotary veneers) using rotary laces, etc., and cutting these into appropriate dimensions. It was in good condition. However, due to the premise of using low-grade logs, the resulting rotary lace veneer had various drawbacks. For example, there are uneven parts, joints, etc. scattered in a single veneer, and when cutting raw material veneer from these, these parts are avoided when cutting (
The yield rate of wood veneer was poor because the defective parts were removed. Moreover, when not removed, this appeared on the surface of the laminated veneer as a product, making the laminated veneer a defective product.

去する各工程を含むことを特徴とする。[Disclosure of the Invention] This invention involves a process of continuously obtaining rotary veneers from logs using a rotary lace, and then cutting the rotary veneers so that the cutting lines pass through the defective parts scattered in the rotary veneers to obtain veneers of predetermined dimensions. The process of obtaining the board, the next step is to stack the veneers with adhesive interposed, and press them between templates to create a flitch.Then, the defective parts that appear at the ends of the flitch are cut and removed. It is characterized by including each step.
以下実施例として示した図面により説明する。An explanation will be given below with reference to drawings shown as examples.

This is bleached and dyed as necessary to produce raw material veneer. A suitable number of raw material veneers are laminated with an adhesive interposed therebetween, and the flitch 6 is obtained by sandwiching and pressing between mold plates. This flitch 6 shows a defect 3 at its end 8. As shown in FIG. Since the end face of the flitch 6 is extremely uneven, it is cut and removed. Therefore, it is cut along the cutting line 7.
これ以後は常法によりスライスして集成単板を得るので
ある。After this, the laminated veneer is obtained by slicing in the usual manner.

集成単板が得られた。Example Tepa logs approximately 1.5 m in diameter were rotary-laced to a thickness of approximately 1 n+. As shown in FIG. 1, black stains appeared on the obtained rotary veneer. The veneer was cut through the black stain to obtain a veneer with black stains only at the edges. A flitch was created by pressing this veneer with an adhesive using a mold plate. This flitch has the black stain at the end. As shown in FIG. Next, when sawing this into lumber, the edges with defects were cut off to remove the defects, and when this was sliced, laminated veneers with no defects were obtained.
