Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a manufacturing method for manufacturing a three-dimensional board formed by three-dimensional bending while treating the end of the board.

[Background Art] For example, as shown in FIG. 9, a three-dimensional plate in which a front plate 3 is bent into a curved shape and a back plate 6 is attached to the front plate 3 is used as a wall material or the like. In this case, since the end 4 of the top plate 3 is exposed externally, it is necessary to cover the end 4. Therefore, conventionally, the wood end 4 is treated by applying paint 7 to the wood end 4 as shown in FIG. There is a risk of scattering and staining the decorative surface, and if the surface board 3 is made of plywood or the like, there is a problem that the paint 7 will be absorbed from the wood end 4, making it impossible to achieve a beautiful finish. Furthermore, as shown in Fig. 10b, a parting material 8 such as a string is pasted to the butt end 4 with adhesive, but in this case, the adhesive area is small, so there is a risk that the parting material 8 may peel off from the butt end 4. There is. Furthermore, as shown in Fig. 9c, a molded product 9 made of a resin material is attached to the butt end 4, but this method requires a mold, etc. to mold the molded product 9, and is expensive. This is problematic.

[Purpose of the Invention] The present invention has been made in view of the above points, and provides a method for producing a three-dimensional wood-end-treated board in which the end-end treatment can be performed reliably without the need to use paint or resin molded products. The purpose is to provide the following.

[Disclosure of the Invention] According to the method for producing a three-dimensional board treated with wood end according to the present invention, the core material 2 is attached to the back side end of the decorative sheet 1, and the core material 2 is attached to the end surface of the surface board 3. The front side of the decorative sheet 1 is overlapped along the edge of the decorative sheet 1, and then the decorative sheet 1 is folded back so as to be wrapped around the core material 2.
At the same time, the decorative sheet 1 is further folded back and overlaid on the back side of the surface plate 3, and the decorative sheet 1 is covered with the surface plate 3.
The decorative sheet 1 and the core material 2 are then fixed to the back surface of the surface board 1 and the core material 2 is used to treat the edge 4 of the surface board 3. The present invention will now be described in detail with reference to Examples.

The core material 2 is made of a material that is somewhat hard, has a certain degree of elasticity, and is bendable, such as aluminum, copper, iron, hard polyvinyl chloride, hard rubber, or paper. This core material 2 is formed into a square rod shape. Further, the decorative sheet 1 is made of woven fabric, nonwoven fabric, or other material having flexibility and toughness. First, as shown in FIGS. 4a and 4b, the core material 2 is attached to one end of the back surface of the decorative sheet 1 using an adhesive
The core material 2 is attached to the decorative sheet 1 by adhesion. At this time, a bag-shaped cylindrical part 12 is formed at one end of the decorative sheet 1 as shown in FIGS. It is also possible to perform the installation. After attaching the core material 2 to the decorative sheet 1 in this way, the decorative sheet 1 is attached to the end surface of the surface plate 3 formed of plywood, resin plate, iron plate, etc. Overlap on the side. Then, fold back the decorative sheet 1 as shown by the arrow a in Figure 1b, and use the decorative sheet 1 to cover the core material 2 as shown in Figure 1c.
At the same time, the end 4 of the surface board 3 is covered with the decorative sheet 1. Then, the decorative sheet 1 is further folded back as shown by the arrow b in FIG. is fixed to the surface plate 3 with adhesive or staples. After the decorative sheet 1 and the core material 2 are attached to the surface plate 3 in this manner, the surface plate 3 is bent together with the core material 2 as shown in FIG. 1e. When the surface plate 3 is bent in this way, a force d is exerted on both ends of the core material 2 that tries to return to its original state, but the core material 2 is held on the surface plate 3 by the decorative sheet 1. Therefore, a reaction force e of this force d is generated at the center of the core material 2, and the core material 2 is pressed against the surface plate 3. Therefore, due to the pressing of the core material 2 by this reaction force e, a frictional force acts between the core material 2 and the surface plate 3 through the decorative sheet 1, and the surface plate 3 of the decorative sheet 1 and the core material 2
The fixed value is maintained. In this way, the end 4 of the top plate 3 is covered with the decorative sheet 1 as shown in Fig. 3, and the back plate 6 is attached to the top plate 3 as shown in Fig. 2 to finish it as a three-dimensional plate. It is something.

6 to 8 show other embodiments,
In this device, as shown in FIG. 8, curved cut edges 11 are provided on both ends of the surface plate 3.
At this notch edge 11, the end 4 is treated with the decorative sheet 1 with the core material 2 in the same manner as described above.

[Effects of the Invention] As described above, in the present invention, the core material is attached to the back side edge of the decorative sheet, and the decorative sheet is attached to the end surface of the top plate so that the core material runs along the edge of the top plate. Then, fold the decorative sheet so as to wrap it around the core material, cover the end of the surface board with the decorative sheet, and fold the decorative sheet further and overlap it on the back side of the surface board, and then wrap the decorative sheet on the back side of the surface board. Since the top plate is fixed and then bent together with the core material, the core material is pressed against the top board due to the bending of the top board and the core material, and the decorative sheet is attached to the top board while covering the end of the top board. This allows the end of the surface board to be reliably treated without the need to use paint or resin molding.

Claims (1)

[Claims] 1 Attach the core material to the back edge of the decorative sheet,
Lay the front side of the decorative sheet on the end surface of the top board so that the core material runs along the edge of the top board, then fold the decorative sheet around the core material to cover the end of the top board with the decorative sheet and apply the decorative sheet. This method of producing a three-dimensional board with a wood end treatment is characterized in that the sheet is further folded back and stacked on the back side of the top board, a decorative sheet is fixed to the back side of the top board, and then the top board is bent together with the core material.
