Description

[Detailed description of the invention] This invention aims to make effective use of thinned wood by processing wood into a single parallelogram block 1 and continuously gluing them together to form a board. It is something.

Conventionally, it has been difficult to obtain wide boards without warping from small-diameter trees.

Therefore, narrow-width boards are sawn from small-diameter trees as shown in FIG. 1, and then processed into a single parallelogram-shaped block with an inclination angle α as shown in FIG. 2. Next, as shown in Figure 3, each block is successively glued together so that the grain directions of the wood in adjacent rows intersect, creating a wide board. At this time, the deviation of a single block of wood that has been cut is smaller than that of the original plank, and since the wood in adjacent rows is glued together at the ends so that the grain directions intersect, the deviation is further reduced. The blocks cancel each other out. Therefore, wide boards with extremely small deviations can be obtained from small-diameter wood.

This board material can be freely glued to the required size, and it also makes use of previously unused thinned wood to create tables, chairs, boxes, and other products that were previously considered difficult to use with small-diameter wood. It is expected that it will be used in a wide range of other ways.

[Brief explanation of the drawing]

FIG. 1 is a perspective view showing how narrow-width boards are sawn from small-diameter trees. FIG. 2 is a perspective view showing the cutting direction in which a narrow board obtained from small-diameter wood is processed into a single parallelogram block. FIG. 3 is a perspective view showing a single parallelogram block successively glued together at the ends of adjacent rows of wood so that the grain directions of the wood intersect. 1 is a single parallelogram block obtained from a small diameter tree. α is the angle of inclination when cutting a single parallelogram block.

Claims (1)

[Scope of utility model registration request] The wood was processed into a single prismatic block consisting of the upper and lower surfaces of a parallelogram, two opposing sides of the butt end, and two opposing sides of the end, and these were glued together with the sides of the end and the other sides together. A board material characterized by the fact that the sides of the butt ends are glued together so that the wood grain directions bend and intersect.
