Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a decorative laminated wood veneer.

! As shown in Figure 1, a laminated decorative veneer stand used to obtain decorative plywood by pasting onto a base plate (6) such as plywood has been conventionally manufactured in the following manner. That is, wood veneers (1) obtained by rotary slicing of natural logs are laminated with colored adhesive, and this is @2.
By pressing between the concave mold (7) and the convex mold (8) as shown in Figure (a), a flitch (9) as shown in Figure 2 (b) is created.
By slicing this flitch (9) diagonally, the colored adhesive appears as wood grain (10) and a laminated decorative veneer A similar in appearance to natural decorative veneer as shown in Fig. 2 (C) is produced. This is what you get. However, as shown in Figure 8 of the natural decorative veneer BVCIJ obtained directly from natural wood, the radial structure appears as stripes (+l) that intersect with the wood grain (lO), and in the laminated decorative veneer A mentioned above, such stripes ( 11) cannot be expressed, and has not yet reached the point where it closely resembles natural decorative veneer B.

The present invention has been made in view of the above points, and an object of the present invention is to provide a method for manufacturing a laminated decorative veneer that can express a striped pattern of radial tissue and give an appearance that closely resembles that of a natural decorative veneer. The purpose is to

In other words, the zero invention was made by laminating a large number of wood veneers +11 ill..., cutting one flitch (2) in the direction intersecting the laminated surface and separating it into several blocks, each block +31131. Apply blue adhesive to the cut surfaces of... and glue each lock i31 t:l... together with the original cut surfaces to create a flitch (4), and then glue all of this flitch (4) in color. The above object has been achieved by a method for manufacturing a laminated decorative veneer, which is characterized by slicing the laminated decorative veneer in a direction intersecting with l1il+51, and the present invention will be described in detail below with reference to examples.

First, by the same procedure as in Fig. 2(a)
As shown in Figure 4(a), create a complete Furi Sochi (2).Next, apply this flitch (2) to a wooden veneer (1) as shown in Figure 4(b).

Divide into 31... In order to create a natural look, it is preferable that the cut surface is not flat. Apply a dark colored adhesive to the cut surface of each otsuk +31 +31... divided into a plurality of parts as shown in Fig. 4 (
As shown in C), these blocks +31 +31... are integrated by aligning their original cut surfaces. Next, slice the flitch (4) created in this way so that it intersects with the adhesive layer (5), and make the radial tissue stripes (ll) where the adhesive layer (6) intersects with the wood grain (10). A laminated decorative veneer with an appearance similar to that shown in Fig. I8 is obtained.

The one shown in Figure 5 represents the stripes (11) of the radial tissue.
This is to explain another method of rice cracking, first of all, Figure 2 (a) I
Using the same procedure as in (b), the flitch (I) as shown in Figure 5 (-) is

As shown in Figure (b), glue is applied to the saws (1 Veneer 04)(
By inserting and fixing a flitch (which may be a natural veneer) into the saw-grained grout as shown in Figure 5 (C), and slicing this flitch 02) in a direction that intersects the laminated veneer (I4). , I5 (d) As shown in VC, a laminated decorative veneer is obtained in which the cut surface of the laminated veneer (14) appears as stripes (0) of radial texture intersecting with the wood grain (lO). Here, it is preferable to use a laminated veneer 04) that is dyed in a dark color (T==). Fig. 6 shows a method similar to that in Fig. 5, in which a flitch (15) is created in the same manner as in Fig. Figure 6 (b
Cut into multiple blocks (16) (16)... like l, apply adhesive to the cut surface of each block (16) (18)... and make each block (+6) (1 phrase). Insert a thin laminated veneer 04) between them as shown in Figure I6 (C) i, r:
In this state, apply pressure from both sides (in the direction of the arrow in Fig. 6(d)), and sandwich the laminated veneer (14) between each block (1 piece (1 piece) as shown in Fig. 6(d)). This flitch (1η

As shown in the figure (el), the cut surface of the laminated veneer (14) has a wood grain (l
A laminated decorative veneer that appears as stripes of radial tissue intersecting with O) is obtained.

As described above, the present invention involves cutting a flitch formed by laminating a large number of wood veneers in a direction intersecting the laminated surface into several blocks, and applying a colored adhesive to the cut surface of each block. This is because each block is glued together at its original cut surface to create a flitch, and then this flitch is sliced in a direction intersecting the layer of colored adhesive to produce laminated decorative veneer. , it is possible to obtain a laminated decorative veneer in which the cut surface of the colored adhesive layer appears on the surface as stripes of radial tissue, and it is possible to obtain a laminated decorative veneer that has an appearance very similar to natural decorative veneer. It is possible.

Claims (1)

[Claims] fll Formed by laminating a large number of wood veneers, the T-flitch is cut in the direction intersecting the laminated surface, separated into several D-shafts, and colored adhesive is applied to the cut surface of each block to form each block. A method for producing a laminated decorative veneer, which is characterized in that a flitch is created by bonding and integrating the flitches at the original cut surface, and then the flitch is sliced in a direction intersecting the layer of colored adhesive.
