However, in the above-mentioned conventional example, the surface material e is formed after the arcuate surface b is formed on the core material a.
It is difficult to align the position of the core material a in the width direction and the position of the surface material e in the width direction for bonding, and the position of the surface material e is displaced, so that the surface material e cannot be accurately attached. In addition, the surface material e must be pressed and adhered to the surface of the core material a, and the surface material e must be bent and adhered along the arcuate surface b, resulting in a complicated adhesion process.
Further, the surface material e is lined with a base material c such as plywood on the back surface side, and when bending and adhering along the arcuate surface b, the force of spring back may act and peel off, which makes it difficult to manufacture. There is a problem.

The present invention has been made in view of the above-mentioned points, and the surface material can be attached to the core material by accurately aligning the position with the core material, and the end portion of the surface material can be easily bent and bonded. It is another object of the present invention to provide a method for manufacturing a decorative panel that does not cause the surface material to peel off due to springback or the like.

[0005]

In order to solve the above problems, in the method for manufacturing a decorative panel according to the first aspect of the present invention, a surface material 2 having substantially the same width as the width of the core material 1 is adhered to the surface of the core material 1. Then, both ends of the core material 1 are shaved off to form the cutouts 3 and the back surface of the surface material 2 is also shaved off at the cutouts 3 to form thin surface material parts 4, and then the core material 1 is cut.

The method for manufacturing a decorative panel according to a second aspect of the present invention is the method of manufacturing the decorative panel according to the first aspect, in which both ends of the core material 1 are scraped off to form the cutouts 3 and the surface material 2 is formed at the cutouts 3. When the back surface of the core material 1 is also scraped off to form the thin-walled surface material portion 4, the core material 1 is cut away to further deeply cut into the entering corner between the ground surface 5 of the core material 1 and the thin-walled surface material portion 4. The recess 7 is formed, and when the thin surface material portion 4 is bent along the scraped surface 5, the recess 7 is filled with a filler 6 such as a hot-melt resin. When the filling material 6 is set at a predetermined position and the thin surface material portion 4 is bent, the filling material 6 can be smoothly and smoothly filled in the gap between the scraped surface 5 and the thin surface material portion 4 to prevent further cracking.

According to a third aspect of the present invention, in the method for manufacturing a decorative panel according to the first or second aspect , the back surface material 8 is also attached to the back surface side of the core material 1 so as to be integrated, and both ends of the core material 1 are formed. It is characterized in that both sides of the back surface material 8 are also shaved off when the notch 3 is formed by scraping off the portion. Even if the back surface material 8 is attached to the back surface side of the core material 1, the surface can be similarly made up to form a decorative panel.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION A decorative panel has a core material 1 as shown in FIG.
And the front surface material 2 and the back surface material 8. Core material 1 is MDF
It is made of board, particle board, etc. and has a flat plate shape. The surface material 2 is a projecting plate on the surface of the base material portion 2a such as plywood,
The decorative material 2b such as a film is integrally laminated, and the width of the surface material 2 is the same as the width of the core material 1. The back material 8 is formed of plywood or the like, and the width of the back material 8 is slightly narrower than that of the core material 1.

In order to manufacture a decorative panel, it is manufactured as follows in the process shown in FIG. First, Fig. 1
As shown in (a), the surface material 2 is overlaid and adhered on the front surface of the core material 1, and the back surface material 8 is overlaid and adhered on the back surface of the core material 1. When the surface material 2 and the back surface material 8 are overlapped and bonded to the core material 1, the surface material 2 and the back surface material 8 can be easily aligned and bonded to the core material 1. Further, when the front surface material 2 and the back surface material 8 are adhered to the core material 1, they are adhered via an adhesive such as a thermosetting resin adhesive and are integrated by a hot press or the like. After the front surface material 2 and the back surface material 8 are integrated with the core material 1 as described above, the cutout portions (the portions shown by cross hatching) 3'on both sides of the core material 1 shown in FIG. Processing is performed, and notches 3 are formed on both sides of the core 1 as shown in FIG. When the notch 3 is cut out, both ends of the back material 8 are also cut. Further, in the case of this example, the cutouts 3 are cut out to form arcuate cut surfaces 5 on both sides of the core material 1. Further, when the notch 3 is formed on both sides of the core material 1 by carving, the back surface side of the surface material 2 is also 0.5 to 0.6 mm.
The thin surface material portions 4 are formed on both sides of the surface material 2 by being scraped off to some extent. Next, the thin surface material portion 4 is bent along the shaving surface 5 and the thin surface material portion 4 is bonded to the shaving surface 5. At this time as well, it is bonded with an adhesive such as a thermosetting resin-based adhesive, and is bent and bonded by a hot press or the like. When the thin surface material portion 4 is bent and adhered, a filling material 6 such as a hot melt resin is filled between the scraped surface 5 and the thin surface material portion 4 and melted when heat is applied by a hot press. The filler 6 reaches the gap between the scraped surface 5 and the thin surface material portion 4, and the filler 6 is filled in the gap. As described above, since the thin surface material portion 4 thinner than the surface material 2 is bent and bonded, it can be bonded by spring back or the like without opening the mouth. Further, when the filling material 6 such as a hot melt resin is filled, it is possible to prevent the thin surface material portion 4 from opening by spring back, and the gap is filled so that the R portion of the thin surface material portion 4 is cracked by the impact. It can be prevented.

FIG. 3 shows another example. When the notch 3 is cut out after the front surface material 2 and the back surface material 8 are attached to the core material 1 and integrated with each other, the end surface of the core material 1 or the back surface material 8 is formed by the vertical surface 5a and the inclined surfaces 5b, 5c. A surface 5 is formed. In this case as well, the back surface side of the surface material 2 is shaved to form the thin surface material portion 4, and the inclined surface 5c and the thin surface material portion 4 are formed at the entering corner between the thin surface material portion 4 and the scraped surface 5. A recess 7 is formed so as to be sandwiched between the back surface and the back surface. Before the thin surface material portion 4 is bent, the recess 7 is filled with a filler 6 such as a hot-melt resin as shown in FIG. 3A, and the thin surface material portion 4 is filled with the filler material 6 as shown in FIG. 3B. Although it is bent and adhered, the filler 6 such as a hot-melt resin melts and goes around, and the gaps are filled in completely.

The above method for manufacturing a decorative panel can be effectively used for manufacturing a door panel of furniture.
