継ぎ合せ部の色調，木目柄が不自然にならないよ
うに工夫していた。 When defects such as knots, skin infiltration, burrs, chips, insect holes, etc. are exposed on the surface of the wood veneer, the conventional method for repairing these defects is to repair the defects that occur during sawing of the wood veneer. Select a piece of scrap material with a color tone and wood grain pattern similar to the defective area, and insert it into the cutout hole of the wooden veneer from which the defective area has been cut out.The color tone and wood grain pattern of the joint will be unnatural. I was trying to make sure that didn't happen.

粧合板６とするものである。 An embodiment of this invention is shown in FIG. That is, this method for repairing defects in a wood veneer is a method for repairing defects in a wood veneer when manufacturing decorative plywood by pasting the wood veneer 2 on a baseboard 1, and is a method for repairing defects in a wood veneer when adhesive is applied using a glue spreader. The wood veneer 2 is placed on the base plate 1 coated with the above-mentioned wood veneer 2, and the wood veneer 2 is pasted with a slip mat, and as shown in FIG. , c is oriented toward the wood grain, and the triangular shape consisting of two long sides b, c and one short side a is cut out with a knife, and the resulting triangular section 4 is cut out as shown in Figure B. The short side 4a containing the defective part is cut out parallel to the short side a, and the defective part 3 is then cut out to form a triangular section 4' whose cut edge is formed by the cutting process. Move the wooden veneer in the direction of the arrow mark P shown in FIG. Close the gap, and as shown in Figure 2, tap the long sides 5a, 5a of the triangular cutout hole 5 that swelled up when cutting with a knife with a mallet or push it with your hands to stretch it inward. After repairing by closing the gap between the long side of the cutout hole 5 and the long side of the triangular section 4' and making them face each other, the repaired wood veneer 2 is pressed and bonded onto the base plate 1 using a hot press. Then, the decorative plywood 6 is obtained.

を有する。 As described above, the method for repairing a defective part of a wooden veneer according to the present invention includes the steps of placing a wooden veneer having a defective part on a base plate coated with an adhesive, and placing the defective part near the inner side of the short side. a cutting step of cutting out the wood veneer into a triangular shape consisting of two long sides and one short side so that the long side faces the grain direction, and the defective part of the triangular section obtained by the cutting process A defect removal step in which the included short sides are cut parallel to the short sides, and a triangular cut-out hole in the wooden veneer is formed by cutting out the short side of the triangular section from which the defect removal process has been performed. a step of making the long side of the triangular cutout hole of the wooden veneer face the short side and extending it inward to make it come into contact with the long side of the triangular section; Since this method includes the step of press-bonding the wooden veneer onto the base plate while they are in contact with each other, there is no need for the difficult work of finding a board material with a color tone and grain pattern similar to the defective part. This has the effect of being able to perform the repair without causing discomfort in the change in color tone and wood grain pattern at the joint portion of the repaired area, and restoring the natural color tone and wood grain pattern on the wood surface.
