4のものである)。First, a colored adhesive 1 that closely resembles the wood grain color of a material such as Japanese cypress is applied to the application roll 5, and the application roll 5 is applied to the surface of the spring wood veneer 2 that has been dyed in the color of the spring wood of a material such as Japanese cypress. The colored adhesive 1a is applied as shown in the second section, and the colored adhesive 1a is cured by pressing through a release sheet. At this time, the size and depth of the concave and convex portions 6 of the applicator roll 5 vary depending on the target tree species and the colored adhesive 1a used.
The approximate depth of the recess is approximately 0.1 to 1.0 mm. Spring wood veneer 2 with this colored adhesive 1a applied in spots
A lamination adhesive is applied to the spring material using a normal roll coater, and a plurality of spring material veneers 2 are stacked and press-formed to form a flitch. At this time, when obtaining the straight-grained wood veneer 3, as shown in No. 30(a), the upper and lower molds 8a of the straight-grain mold 8,
