FIG. 1 exemplifies a case where this assembled flitch is used. When using the material flitch (1) either as a simple substance or as an assembly, the flitch having a high water content above the fiber saturation point is used.

成しても良い。In the first step, the material flitch (1) is first cut in the thickness direction thereof along a cutting line (2) forming a predetermined curve or a cutting line of a predetermined shape including a curved portion at least in part. , Separated into a plurality of cut pieces (1a) (1b) (1c). This cutting is generally performed using a thread saw. Further, the cutting line (2) is determined according to the curved pattern to be finally obtained, and in the embodiment shown in FIG. 2, the corners of the square material flitch (1) facing each other. Is formed in the shape of an arc having a radius of about 1/2 of the side length (l) (1 / 2l). Therefore, the material flitch (1) has one cut piece (1a) which is the main part of the material flitch,
It is cut and separated into two fan-shaped cut pieces (1b) and (1c). In addition to the above-described aspect, the cutting line may include a curved portion in part. For example, as in the modification shown in FIG. 8, the intermediate portion may be formed as a straight line portion (12a) and a cutting line (12) having curved portions (12b) (12b) at both ends thereof.

んだ曲線模様を形成することができる。Next, as the second step, the cut pieces (1a) (1b) (1c)
Are sandwiched between the cut surfaces (2a) and (2a) to be bonded and integrated with each other to form a curved pattern flitch (11). The veneer (3) is manufactured separately from the wood of the same or different tree species as the material flitch (1), and if the pattern is desired to be emphasized, those having different appearances such as colors are used. Further, the veneer (3) is flexibly deformed along the curved cutting sides of the cut pieces (1a) (1b) (1c), and such deformation causes trouble such as cracking. In order to be carried out without any action, a wet one having a high water content above the fiber saturation point is used, and preferably a relatively thin and flexible tree species having a thickness of about 1 to 3 mm is used. . Further, it may be softened if necessary. Then, the pattern-forming single plate (3) is inserted and adhered by applying an adhesive of a kind capable of adhering to wet wood to each joint surface and then performing the single bonding as shown in FIG. The plate (3) is interposed between the cut surfaces of the cut pieces (1a) (1b) (1c). And as shown in FIG. 4, 1
The cutting piece (1a) is cut by the clamping jig (4) including one L-shaped fixing jig (4a) and the other three L-shaped movable jigs (4b) (4b) (4b). ) (1b) (1c) and the veneer (3) are pressed by applying pressure from four directions to complete the bonding, and therefore the veneer (3) is attached to the cut surface. It is fixed in a flexurally deformed state. As described above, one single plate (3) having a width of about 1 to 3 mm is used. If it is desired to form a linear pattern having a width wider than that, refer to FIG. As shown, a plurality of single plates (3) and (3) are laminated and interveningly bonded. For example, when it is desired to form a curved pattern having a width of 9 mm, it is possible to easily meet the above-mentioned demand by using three single plates having a thickness of 3 mm in a stacked manner. Further, in this case, a plurality of veneers of different colors are used, or only one of the three veneers (3) in the middle is used for the other two.
By using a different color from the sheet, it is possible to form a more interesting curved pattern.

ある。In the third step, as a preparatory step, precision cutting / cutting processing is performed to finish both sides and four circumferential side surfaces of the curved pattern flitch (11) that has been bonded, and if necessary, this precision cutting / cutting processing is further performed. Finished curved pattern flitch (1
As shown in Fig. 5, a plurality of 1) are placed side by side on the wood (5) in a state where adhesive is applied to the joining surfaces of each other, and they are adhered while applying pressure from the vertical and horizontal directions. Form a large flitch (10) with wood. At this time, in order to prevent breakage when cutting the slicer, a thin wood or other sheet material may be adhered around the flitch. Then, the above wood (5) portion is held by the chuck of the slicer, and a large flitch (10) composed of an assembly of curved pattern flitch (11) is sliced in the plane direction, and a predetermined flicker as shown in FIG. 6 is obtained.

有効に利用するものである。In each of the above steps in the present invention, namely, the cutting step of the material flitch (1), the step of inserting and bonding the pattern forming veneer, and the slicing step, the processed wood is in a wet state,
In particular, it is carried out under the condition of having a high water content above the fiber saturation point. Therefore, when the water content of the material drops below the fiber saturation point due to a time factor, each step should be performed by adjusting the water content above the fiber saturation point by dipping, water removal or the like. The reason for this is to prevent shape changes due to changes in water content of the material during processing, such as deformation such as cracking and twisting, maintain good workability, and facilitate accurate processing. Is. That is, wood having a water content above the fiber saturation point effectively retains a stable shape without any change in the physical or mechanical properties of the material even if the water content changes more than that.

As such an adhesive, any adhesive such as an epoxy resin-based or urethane resin-based adhesive may be selected and used. Among them, an adhesive that reacts with moisture to exhibit a curing adhesive action, for example, a moisture-curing type one liquid The adhesive polyurethane resin adhesive has excellent adhesiveness, is easy to cut after curing, and has little discoloration of the glue line after adhesion, and therefore can be preferably used.

Slicing was performed in the plane direction, that is, parallel to the plane where the curved pattern exists, to obtain a decorative veneer (A) having a thickness of 0.3 mm. As shown in FIG. 2, the decorative veneer (A) has a 3 mm wide curved pattern (6) formed by adjacent pattern forming veneers (3) of the unit flitch portion continuous in a semi-arc shape in plan view. By arranging a plurality of the decorative veneers (A) while inverting them, a circular pattern as shown by a chain line in FIG. 6 could be obtained.

There is no difficulty in manufacturing and it is suitable for industrial production as compared with a case where a curved member is cut out from another material and then reinserted into the corresponding hole to form a curved pattern flitch. . In addition, since each step is carried out at a high water content above the fiber saturation point of the material, it is possible to obtain a decorative veneer with stable shape, size, etc. Since it is inserted and bonded between the cut pieces of the material flitch by using, the single plate can be easily flexibly deformed without any trouble even when a curved pattern having a relatively small curvature is formed. Further, by inserting a plurality of the single plates in a superposed manner, it is possible to form a curved pattern having an arbitrarily wide width, which is excellent in the flexibility of selecting the pattern mode.
