、 （Ｉ） ）。(7)'The surface of the obtained composite veneer 7 is rubbed with a roll brush 8
Or brush it by sandblasting etc.
Due to the difference in hardness between the wood layer and the colored adhesive layer of the cut surface of the textured veneer 3', a laminated decorative veneer 9 is obtained which has been subjected to a relief treatment that exhibits unevenness along the grain pattern ( Same figure (6)
, (I)).

プなものとすることができる。In addition, in this embodiment, a summer material colored adhesive 4' is used as the adhesive used for forming the flitch assembly.
′ and the summer material color colored adhesive 4 that is applied and hardened in the first time to form the summer material part, the first summer material color colored adhesive 4
Since the amount of coating is kept to a medium amount for the summer wood part Kll, the penetration of the summer wood colored adhesive 4 into the cracks on the back of the dyed veneer 3 is reduced, and the reproduced summer wood part is improved. It is possible to make the wood grain sharp.

う問題点を有する。As described above, the method for manufacturing a decorative veneer of the present invention includes a summer wood part forming step of applying and curing a summer wood wrapping adhesive on the surface of a wood veneer for spring wood to form a summer wood part; A composite flitch forming step in which a plurality of the spring timber veneers are laminated and pressure-bonded with the forming surface of the summer timber portion in a predetermined direction using an adhesive to obtain a composite flitch; Since this method includes a slicing step of slicing from a predetermined direction that intersects with the laminated surface, it has the effect that the reproduced summer wood portion of the wood grain pattern can be seamless and rich in natural feel. - As mentioned above, - As a means of imparting a wavy width change to the summer wood portion of a laminated decorative veneer, it is possible to apply an uneven finish to the surface of the wood material veneer using an embossing roll or an uneven mold. Although this method has been used in the past, it requires high pressure to process the irregularities, and has the drawbacks of cracking and warping of the veneer.Also, if the moisture content of the veneer is high, The stability of the unevenness is poor when the applied unevenness is measured by drying treatment etc.
It has some problems.

、不良発生率を大幅に低減化できる。That is, this veneer manufacturing method is a method of rotary slicing a ball-cut log 10 to obtain a rotary slice veneer, and the lace blade 11 used for slicing is swung back and forth to control its feeding. The rotary sliced veneer is sliced while changing its width at regular intervals or randomly, and unevenness is imparted to the surface of the resulting rotary sliced veneer.In this way, the lace blade is used at the manufacturing stage of each veneer. By changing the feed width of 11, the thickness of the veneer is changed to KIR, and as a result of this K, the uneven processing is applied, so that the unevenness of the veneer is stable without being affected by the moisture content of the veneer. It is possible to reproduce the clear serrated annual rings in the laminated decorative veneer produced using this method, and since no pressure treatment is required to impart unevenness, defects such as cracks can be prevented, and the defect rate can be significantly reduced. Can be reduced.
