Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a decorative veneer having straight-grained portions on both sides and a grained portion in the center. At the same time, apply a light colored Ishiku T to both sides of the top of the veneer (!)
Apply e1, and apply uncolored adhesive (4) tm on the top of light color ink (2) and the bottom surface of light color ink (veneer +1 corresponding to RiKK).
Dark colored ink (3) Dark colored ink ($I
Apply a colored adhesive (4) colored in a color similar to that of the veneer (1) K to the underside of the veneer (1) corresponding to K, and apply the light colored ink (2) or apply the uncolored adhesive (number). One of the veneers (1) is layered and bonded with an uncolored adhesive (4) and a colored adhesive (5) to form a laminate. At the same time, the laminated plate (2) is curved so that the curvature gradually increases from one end in the longitudinal direction to the other end to form a composite flitch ■ having a substantially chevron-shaped cross section.

The present invention relates to a method for manufacturing a decorative veneer, characterized by forming a decorative veneer. . Traditionally, the decorative veneer C), which has straight-grained parts on both sides and a board-grained part in the center, was constructed as follows. Figure 1 (a)
), apply the light color ink (2) in the center and the light color ink (3) on both sides by transferring with the transfer sheet (6)K, and then apply the light color ink (the color corresponding to the light color ink (2)) on both sides. Apply light colored ink (!1 and non-colored adhesive (4) on the underside of the board (!1) and apply dark colored ink (3) on top to dark colored ink + 31K on the corresponding veneer (1) and veneer + 1 on the underside.
) Apply colored adhesive (ll) colored in a color close to K [in the figure (a) is the uncolored adhesive (4) being applied, 0 is the colored adhesive (6) being applied], and then apply ink or adhesive. veneer +11
A plurality of sheets are stacked to form a laminate Q as shown in 1FgJ(b), and this laminate is curved so that the curvature gradually increases from one end toward the other end to form a laminate Q as shown in FIG. 1(e). ), and this assembled flitch was sliced on a substantially horizontal plane as shown in Figure 1) to form a decorative veneer (q). The decorative veneer C) has a straight-grained part (Ct) on both sides as shown in Figure 2, and a board-grained part (HE) in the center. When viewed from above (from the direction of the arrow), the dark colored ink (3) is hidden by the colored adhesive (6), and the light colored ink (3) does not penetrate through the adhesive, and the dark and thin wood grain is visible. . In addition, the grain part (C section 113 figure (
As shown in b), when using uncolored adhesive (4), the light colored ink (zl) looks wide and the gloss of the light colored ink (zl) is not erased, and the pale, glossy foot and thick wood grain are visible. However, in such a conventional example, the straight grain part (C1) has a dark and narrow grain, and the board grain part (Ct) has a light and wide grain, and the boundary between the straight grain part (C1) and the board grain part (C) There was a point where some parts felt strange and unnatural.

The present invention has been made in view of the above points, and the object of the present invention is to obtain a nine-faced veneer that closely resembles natural wood without giving any discomfort at the boundary between the straight-grained part and the board-grained part. K provides a method for manufacturing decorative veneers that can be used.

The present invention will be explained in detail below using examples. (1) is Akachisu, Honwaitose 5? It is made by slicing raw wood into tally slices and horizontally slicing it to produce veneers such as tally veneer and sliced veneer. (6) A transfer sheet such as a synthetic resin film, and as shown in FIG.
and dark colored ink (:I) on both sides. Such a transfer sheet is, for example, made of polyester and has a thickness of 50 degrees. In addition, the ink is, for example, nitrate cellulosic, the pigment is ferric oxide, and the coating amount is about 21! /d. Apply a transparent adhesive (7) on the veneer (!), then attach the transfer sheet (6) to the veneer Tll as shown in Figure 4.
Transfer one drop of ink (21) and dark ink (3) onto the transparent adhesive () of the veneer (1) by placing it on top and pressing it, and peel off the transfer sheet (@). Especially the veneer (!
) Apply light color ink (21) to the center of the top surface, and dark color ink (3) to both sides of the top surface. /d, and the conditions for pressing during transfer are, for example, 10 to /a11 for 1 hour. Next, uncolored adhesive (4) is applied on the light colored ink (21) on the veneer (1) or on the lower surface of the veneer +11 corresponding to the light colored ink (2), and on the dark colored ink (3) or on the dark colored ink. Apply colored adhesive +8) with a color similar to veneer (1)K to the bottom surface of veneer tl corresponding to (3), and attach multiple veneers ( 1) are stacked to form a laminate.

In the above figure 4) (C) In the example, light color ink (2)
While applying the non-colored adhesive (4), make a slightly narrower line, and apply the uncolored adhesive (4) by a distance of d (for example, about 20 m
s) It's wide. During the application of this light colored ink (2) and the width of the non-colored adhesive (4) F! Figure 4 - 'r<c'>tt
c As shown, draw a slightly wider area during the application of light colored ink (21),
The time during which the uncolored adhesive (4) is applied may be made narrower than the time during which the light-colored ink (2) is applied.The laminate Q formed as described above is coated with an upper mold ( 8) and the lower m (91) to form an assembled flitch (g) with a substantially mountain-shaped cross section.When pressing with the upper mold (8) and the lower mold (9), from one end a in the longitudinal direction to the other Press so that the curvature gradually increases toward the end (in other words, press so that the lower part is thicker and the upper part is thinner, like a natural standing tree). The decorative veneer opening is formed by slicing on a substantially horizontal plane as shown in the figure.The veneer opening is formed by slicing in this way on a substantially horizontal plane. The grain area (C1) has a light and wide grain as shown in Figure 3(b).The boundary area (C3) between the straight grain area (C8) and the wood grain area (C1) is coated with light color ink (2). When applying the uncolored adhesive (4) to a larger area than the inside, a K-shaped dark color with a thick grain is created, as shown in Figure 7 (a).
Also, during application of light colored ink (2), non-colored adhesive (4)
If the amount of wood during application is reduced, a pale and thin wood grain like K is created as shown in Figure 7(b).

Since the present invention is constructed as described above, if the application of light-colored ink is increased while the uncolored adhesive is applied, a dark and thick wood grain is created at the boundary between the straight-grained part and the board-grained part, and the light-colored ink When applying the uncolored adhesive to a smaller size, the boundary between the straight-grained part and the board-grained part will be lighter and thinner, and the boundary between the thicker, thinner straight-grained part and the lighter, thicker board-grained part will be different. It is possible to obtain a decorative veneer that does not have a Japanese feel and is close to natural wood.
