Description

[Detailed Description of the Invention] This invention relates to a wood decorative board, and more specifically, a small wood veneer pattern processed into the shape of a natural object is attached to a large wood veneer, including the small wood veneer. This invention relates to a wood decorative board with an embroidered pattern.

Conventionally, for furniture such as high-end chests of drawers and sideboards, and for building materials, decorative plywood has been used, which is made by laminating ultra-thin boards called veneers cut from natural wood onto a base plate. These produce natural patterns such as grain patterns, heather, bumps, etc. of natural wood, but by stitching decorative patterns on the wood veneer with various fiber threads, it is possible to prevent cracks on the back of the wood veneer. Wooden decorative boards that reinforce and hide defects such as holes and that also exhibit a variety of patterns on natural wood grains are well known.

This conventional wooden decorative board, which is made by applying embroidery to a veneer board and pasting it onto plywood, has the disadvantage that it lacks artistic interest because it can only be embroidered with a uniform flat pattern.
When pasting an embroidered veneer on plywood, a resin layer with approximately the same thickness as the embroidery thread layer protruding from the back of the veneer is applied only to the areas where there is no thread, and the back surface of the veneer is roughly covered. After it was flattened, it was attached to the base plate. Therefore, there were disadvantages in that the process before pasting was troublesome and workability was poor.

The purpose of this invention is to eliminate the above-mentioned drawbacks, and its feature is that a backing member is attached to the back side of the veneer using thermoplastic adhesive, and then processed into a specific shape on the surface of a large veneer. After temporarily attaching a decorative veneer made of small veneers, and applying embroidery to both of the veneers, a large veneer is placed on the base plate, and a small veneer is placed on top of the large veneer. A small veneer is pasted on top of each veneer, a synthetic resin layer sufficiently thicker than the thickness of the embroidery thread is placed on both veneers, and the surface of this layer is polished to make it smooth, creating a delicate beauty full of variation. To provide a wood decorative board having a three-dimensional shoulder pattern. An embodiment of the present invention shown in the drawings will be described in detail below.

The decorative board of this invention is processed as follows. First, as shown in FIG. 1(a), an ultra-thin veneer 11 made by cutting 7 pieces of natural wood is pre-prepared with the thickness and approximate thickness of the veneer as shown in FIG. 1(b). A backing member 12 such as Japanese paper or cloth of equal thickness is bonded with thermoplastic adhesive t3.
Add the thickness of the adhesive patch 13a to the thickness of the adhesive plate 11.
As shown in FIG. 2, the outline of a decorative veneer 2, which will be described later and which has been processed into a specific shape, is attached to the veneer 1 to which a thermoplastic adhesive 13b with a thickness equal to the thickness of the veneer 13b is attached. Contour stitching 3 is performed using an oil-repellent thread.

Next, as shown in FIGS. 3(a) to (C), a veneer 2 is sewn onto the outline sewing area on the veneer 1 in the same way as the veneer 1.
A backing member 22 is pasted on the back side of 1 with thermoplastic adhesive 23a, and when the backing member is not pasted, the same adhesive 2 as above is applied to the other side.
A decorative veneer board 2 having a specific shape, 3b attached thereto, is attached to the trunk of a pine tree in this embodiment by partially heating and press-bonding it with a heating jig.

After this, as shown in FIGS. 4(a) to (Q) and FIG. Apply embroidery 4b to 4d on the leaves.

As shown in FIG.
The veneer 1, the decorative veneer 2, and the base plate 6 are bonded together using the thermoplastic adhesives 13a, 13b and 23a, 23b, which are then placed on top and heated.

When this bonding process is completed, as shown in FIG. 7(a), the adhesion aid (Sheep) 71 is first sprayed several times on the decorative veneer to reduce surface irregularities, and then
As shown in Figure (b), the polyester resin solvent 72 is applied multiple times with a brush to further reduce surface irregularities. In this way, a transparent protective layer 7 is formed on the decorative veneer, and after polishing and smoothing this protective layer 7 with sand vapor as shown in FIG. 7(C), A finishing spray is applied to form a surface layer 8.

As described above, the present invention partially attaches a decorative veneer board consisting of a small veneer board processed into a specific shape onto the surface of a large veneer material, which has been bleached with thermoplastic adhesive on the back side of the veneer board. After temporary attachment and embroidery on both of the veneers, the large veneer is pasted on the base plate, the small veneer is pasted on the large veneer, and the embroidery thread is placed on both the veneers. A sufficiently thick synthetic resin layer is provided, and the surface of this layer is polished to make it smooth, resulting in a decorative board that is beautiful and extremely three-dimensional, with an uneven pattern on the surface created by the decorative veneer and embroidery thread layer. The adhesive layer attached to the veneer and plywood absorbs the unevenness of the embroidery thread on the back, and the unevenness on the front can be absorbed by the protective layer applied on top, making it easy to process and mass-produce. It has the advantage of being able to be produced at a low cost because it can be produced automatically.

Claims (1)

[Claims] A small decorative veneer of a specific shape with a thermoplastic resin coated and hardened on the back side of the large veneer is partially attached to the surface of the large veneer, with the backing member attached to the back of the veneer using thermoplastic adhesive. After embroidering the board, attach a large embroidery board to the base board, and a small embroidery board to this large embroidery board, and then embroidery thread that is sufficiently thicker than the thickness of the embroidery thread on both of the embroidery boards.
