A plurality of material veneers coated with adhesive are laminated and bonded by pressure to obtain a frit, and this frittu is sliced from a predetermined direction to form the laminated boundary surface (adhesive layer) of each material veneer along the tree ring line. In the conventional manufacturing method of decorative veneer, which is modeled after veneer, it is extremely difficult to express the unevenness of the annual ring lines and uneven spacing between the annual ring lines, which are characteristic of natural wood, without producing monotonous annual ring lines. In addition, the sliced veneer is dyed to create a color tone that varies in density in stripes along the wood grain layer, but because it is dyed uniformly, the color variation is monotonous and lacks a natural feel in the color tone. There was a problem.

The method for producing a decorative veneer of the present invention includes the steps of laminating a plurality of material veneers via an adhesive and press-bonding them to obtain a primary flitch, and placing the primary flitch in a predetermined position with respect to the laminated surface. A step of slicing the sliced veneer in the width direction or longitudinal direction at an angle of The method includes the steps of laminating the coated sliced veneers alone or in combination with other material veneers via an adhesive and press-bonding them to obtain a secondary flitch, and slicing the secondary flitch.

らが生じる。 1A to 1I are process explanatory diagrams for obtaining sliced veneers in the present invention, and as shown in FIGS. 1A to 1C, rotary veneers or sliced veneers are used. The prepared material veneers 1 are laminated in a flat mold 2 via an adhesive and bonded by pressure to obtain a primary flitch 3, and this primary flitch 3 is sliced at a predetermined angle with respect to the laminated surface. Obtain veneer 4 (approximately 0.2 to 2 mm thick).
At this time, when the primary flitch 3 is sliced at a predetermined angle in the width direction, adhesive layers 5 and veneer layers 6 appear alternately in the width direction, as shown in FIG. 1d.
In each of these sliced veneers 4, the adhesive layer 5 and the veneer layer 6 have different hardnesses, and the veneer layer 6 is softer than the adhesive layer 5. As a result, the surface of the sliced veneer 4 becomes uneven as shown in FIGS. 2 and 3, resulting in uneven thickness.

されていない。 In this way, the dyeing solution 12 applied to the surface of the sliced veneer 4 penetrates into the interior, eliminating the need for dyeing in a high-temperature bath as in the conventional method. Because layer 5 has unevenness and thickness unevenness (1.0mm thick slice has a thickness variation of about 0.8 to 1.2mm), pressure unevenness occurs during compaction, which causes unevenness in dye permeability. This may cause color variations. Furthermore, since the dye is difficult to penetrate into the adhesive layer 5 in the sliced veneer 4 and its surroundings (they are uniformly dyed in a high temperature bath), color variations become even more pronounced. FIG. 4 shows the degree of penetration into the sliced veneer 4 when the staining solution 12 is applied to both sides, and the periphery of the adhesive layer 6 is only slightly dyed compared to the central part of the veneer layer 6. do not have.

As shown in FIG. The secondary adhesive layer 9 on which the fritches 8 are formed appears on the material surface to express the annual ring lines, and the secondary adhesive layer 9 can express the uneven annual ring lines. The distance A between the agent layers 9 becomes uneven. In addition, as mentioned above, uneven dyeing occurs in the sliced veneer 4 itself, so color variations are formed in the decorative veneer obtained by slicing the secondary fritches. Obtainable.
