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, the end 4 of the top plate 3 will be exposed as an external appearance, so
It is necessary to perform a coating treatment on the wood end 4. Therefore, conventionally, the wood end 4 is treated by applying paint 7 to the wood end 4 as shown in FIG. 10(a). 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 is absorbed from the wood end 4, making it impossible to achieve a beautiful finish. In addition, as shown in Fig. 10(b), a parting material 8 such as a string is pasted to the butt end 4 with adhesive, but in this case, the parting part 8 is peeled off from the butt end 4 because the adhesive area is small. There is a risk of it getting lost. Furthermore, as shown in Figure @9 (c), a molded product 9 made of a resin material is attached to the butt end 4, but in this case, the molded product 9
This method requires a mold, etc. for molding, which poses a problem in terms of cost.

1 Purpose of the Invention 1 The present invention has been made in view of the problems described in L, and provides a three-dimensional board with wood end treatment that can be performed reliably without the need to use paint or resin molded products. The purpose is to provide a manufacturing method.

``Disclosure of the Invention'' The method for manufacturing a three-dimensional board treated with wood end according to the present invention is such that the core material 2 is placed on the back side end of the decorative sheet, and the core material is placed on the end surface of the top plate 3. 2. Overlap the front side of the decorative sheet 1 along the edge of the front thl board 3, then fold back the decorative sheet 1 so that it can be wrapped around the core material 2, and wrap the front board 3.
Cover the wood end 4 with the decorative sheet, fold the decorative sheet again, stack it on the back side of the surface plate 3, and apply the decorative sheet 1.
is fixed to the back of the surface plate 3, and then the surface plate 1 is bent together with the core material 2, and the surface plate; ]ko4
The present invention will be described in detail below with reference to Examples.

Core material 2 is aluminum, copper, iron, hard polyvinyl chloride,
It is made of a material that is hard to some extent and has a certain degree of elasticity, such as hard rubber or paper, and can be bent. This core material 2 is formed into a square rod shape. Also decorative sheet 1
It is made of woven fabric, non-woven fabric, or other material having flexibility and toughness. First, the core material 2 is attached to the decorative sheet 1 by bonding the core material 2 to one end of the back surface of the decorative sheet 1 with an adhesive 10, as shown in FIG. 4(,)(b). At this time, fj35 diagram (a) (+1)
A bag-shaped cylindrical portion 12 is formed at one end of the decorative sheet 1 as shown in FIG.
The core material 2 may be attached to the core material 1.

After attaching the core material 2 to the decorative sheet 1 in this way, as shown in FIGS. ] on its surface side.Then, fold back the "decorative sheet" as shown by arrow a in FIG. 1(b) and wrap the core material 2 with the decorative sheet 1 as shown in FIG. wood[

While applying a tensile force in the direction of arrow C in Figure (d), the portion of the decorative sheet 1 that is folded back to the back side of the surface plate 3 is fixed to the surface plate 3 using an adhesive or a stabilizer. After attaching the decorative sheet 1 and the core material 2 to the surface plate 3 in this way, bend the surface plate 3 together with the core material 2 as shown in FIG. 1(e). When the core material 2 is bent, a force d is exerted on both ends of the core material 2 to return it to its original state, but since the core material 2 is held by the surface plate 3 by the decorative sheet 1, this force is A reaction force e of d is generated in the center of the core material 2, and the core material 2 is pressed against the surface plate 3. Therefore, the decorative sheet 1 is pushed by the core material 2 by this reaction force e = l. Frictional force acts on the opening between the core material 2 and the surface plate 3, and the fixation of the decorative sheet 1 and the core material 2 to the surface plate 3 is maintained.In this way, the third
As shown in the figure, the end 4 of the top plate 3 is covered with a decorative sheet 1, and a back plate 6 is attached to the top plate 3 as shown in FIG. 2 to finish it as a three-dimensional plate.

6 to 8 show another embodiment, in which, as shown in FIG. 8, curved notch edges 11 are provided on both sides of the surface plate 3. In 11, the end 4 is treated with the decorative sheet 1 having the core material 2 as in the case of ``-''.

[Effects of the Invention] As described above, in the present invention, a 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 along the core material or the edge of the top plate. Then fold the decorative sheet around the core material to cover the end of the surface board with the decorative sheet, fold the decorative sheet back again, overlap the back side of the surface board, and wrap the decorative sheet around the back of the surface board. Then, the top plate is bent together with the core material, so that the core material is pressed against the top plate due to the bending of the top plate and the core material, and the decorative sheet covers the end of the top plate and then bends the top plate together with the core material. Held to! This makes it possible to reliably treat the edge of the surface board without the need to use paint or resin moldings.
