Description of the Related Art Solid sawn timber has been often used as the above-mentioned material, but in recent years, from the viewpoint of reduction of high quality raw wood, ease of chemical treatment, stability of dimensional accuracy, etc. There is a tendency that the number of cases in which a veneer veneer (hereinafter, simply referred to as veneer) is laminated and bonded to a plurality of blocks having arbitrary sizes and used in place of sawn wood is gradually increased.

粧材を別途に接着する製法が挙げられる。[0003] In the conventional general manufacturing method, even if a single plate laminated material is manufactured with any size, defects such as knots, knot holes, and crucibles are almost always obtained so as to always obtain a defect-free material. A manufacturing method in which a veneer laminate is manufactured using only the best-grade veneer that does not have it, or a veneer laminate is manufactured using only veneers from which most of the defects have been removed in advance, and then sawed into multiple blocks. In addition, as a special manufacturing method, a veneer laminated material is manufactured by using a good-quality veneer with relatively few defects, and then the veneer laminated material is processed into a plurality of blocks, and further if necessary. Then, after finishing processing, regardless of whether or not there are actual defects, a thick good-quality cosmetic material sufficient to cover the defects is separately attached to the desired outer surface of the block so that the appearance of the defects can be dealt with. The manufacturing method is mentioned.

競合する際に、価格面で劣勢となる問題があった。However, in the former general production method, when only the best grade veneer is used,
Since the raw material cost is extremely high, and when using only a single plate from which most of the defects have been removed beforehand, the defect-free parts in the vicinity of the defects are removed together, and the material yield decreases, or The manufacturing cost will inevitably increase due to factors such as an excessive increase in the number of horizontal and / or vertical perforations of the removed veneer to a size equivalent to a veneer laminated material, resulting in high manufacturing costs. Similarly, even in the latter special manufacturing method, since the material cost of a thick good quality cosmetic material sufficient to cover up the drawbacks becomes expensive, there is also a problem that the manufacturing cost also becomes high, In the end, all of these conventional manufacturing methods had a problem of price inferiority when competing with sawn timber.

案する。The present invention was developed in order to solve the above-mentioned drawbacks of the conventional manufacturing method. Specifically, a plurality of veneers that allow the existence of defects of appropriate size are used. After manufacturing the veneer laminated material with, the veneer laminated material is molded into a plurality of blocks of arbitrary size, and then a portion having a defect of a predetermined size or more on the desired outer surface of each block is cut off, A method for manufacturing a raw material is proposed, which is characterized in that the remaining portions are successively joined in the longitudinal direction and further cut into a desired length.

て、素材5を製造するものである。As shown in FIG. 1, the method for manufacturing a raw material according to the present invention comprises manufacturing a single-plate laminated material 3 using a plurality of single-plates 1 each of which is allowed to have a defect 2 of an appropriate size. The veneer laminated material 3 is molded into a plurality of blocks 4 of arbitrary size, and then a portion 4b where a defect 2 of a predetermined size or more is present is cut off on a desired outer surface of each block 4 and the remaining portion 4a is cut off. The material 5 is manufactured by successively joining the materials in the longitudinal direction and further cutting them into desired lengths.

Therefore, the desired outer surface of the block has a defect of a predetermined size or more. Although the structure of cutting the part is adopted, it is natural that it is desirable to reduce the frequency of cutting the part having a defect as much as possible even in the present invention. It is preferable to use a veneer positioned in a layer that has as few defects as possible,
Even for a single plate located in the intermediate layer, it is preferable to use it after removing excessively large defects (for example, defects significantly larger than the assumed minimum width of the block) in advance.

It is appropriate to use the finger joint as in the embodiment for the joining in the longitudinal direction because it includes the form and because of the simplicity of joining, but in any case, the cutting of the portion where the defect exists The joining of the remaining portion and the remaining portion may be a state in which at least some of the steps proceed simultaneously.

It also includes a single plate laminated in the direction orthogonal to the fiber direction.

代る有益な素材の供給を可能化するものである。As described above, the method for producing a raw material according to the present invention is for producing a laminated veneer material by using a plurality of veneers which allow the existence of defects of appropriate size. The raw material cost is extremely low, and it is not necessary to cut away parts other than parts where defects of a predetermined size or more exist on the desired outer surface of the block, such as parts where defects exist inside the block. Compared with removing most of the defects of the plate, the material yield is improved, and the number of steps for joining blocks is increased at a rate smaller than the rate at which the steps for joining veneers are reduced. Generally, the manufacturing cost is low, and there is no need for a cosmetic material to hide defects, or if necessary, even if a cosmetic material is adhered to the desired external surface exclusively for makeup, the required thickness is required. Saga is a special manufacturing method Since it is thin and can be used, the material cost is low, and as a whole, there is an advantage that the manufacturing cost can be reduced compared to any conventional manufacturing method, and it is possible to supply a useful material that replaces the existing lumber. It will be transformed.
