製造方法を提供するものである。Conventionally, as shown in FIGS. 1 and 2, a decorative sheet 2 is pasted on the surface of a board material 1, a part of this board material 1 is cut to directly form a comb-shaped portion 1a, and the A method of manufacturing a decorative board is used in which a curved surface is formed by bending the board material 1 so that the two sides are in contact with each other. In this case, the board 1 itself must be suitable for delicate cutting, so generally laminated plywood is used as the board 1, or a special particle board pressed with only minute chips is used. However, the plate material 1
When laminated plywood is used as the decorative sheet 2, there is a problem that if a vinyl chloride sheet is used as the decorative sheet 2, the conduits of the plywood cause visual loss, and special particle board becomes very expensive. 5-On the other hand, in recent years, when constructing cabinets for furniture and audio equipment, particle board 3, in which the surface layers 3a and 3b are made of fine chips and the middle layer 3c is made of coarse chips, is often used, as shown in FIG. This is cheaper than laminated plywood or special particle board, but if you try to give it a curved surface using the method shown in Figures 1 and 2, it will be difficult to create a delicate comb-shaped finish. Since the comb-like portions are missing, the methods shown in FIGS. 1 and 2 are not suitable. The present invention solves these problems and provides a decorative board that is inexpensive and beautiful, and a method for manufacturing the same.
以下本発明の一実施例について第４図以下の図面ととも
に説明する。An embodiment of the present invention will be described below with reference to FIG. 4 and the following drawings.
まず、第４図に示すように、第１のパーテイクルホード
４として第３図に示したもの、すなわち表層４ａ，４ｂ
が微細チップからなり、中層４ｃが粗いチップからなる
ものを使用し、その表面に化粧シート５を貼り付け、そ
の裏面の曲面付与部に、上記化粧シート５と表層４ａの
一部４ａ″を残して凹部４ｄを形成する。First, as shown in FIG. 4, the first particle ford 4 shown in FIG.
A material is used in which the inner layer 4c is made of fine chips and the middle layer 4c is made of coarse chips, the decorative sheet 5 is pasted on the surface thereof, and the decorative sheet 5 and a part 4a'' of the surface layer 4a are left on the curved surface portion on the back side. to form a recess 4d.
この残り厚みは約１〜２．５ｗＬであるが、第１のパー
ティクルボード４の厚さによつて異なる。次にこの凹部
４ｄ内に全体が微細なチップからなる切削加工に適した
第２のパーティクルボード６を接着する。This remaining thickness is approximately 1 to 2.5 wL, but varies depending on the thickness of the first particle board 4. Next, a second particle board 6, which is made entirely of fine chips and is suitable for cutting, is bonded into the recess 4d.
このとき第２のパーティクルボード６の裏面が、第１の
パーティクルボード４の裏面よりわすかに（約０．３〜
０．６Ｔ＄Ｌ程度）低くなるようにし、これを第５図に

設した多軸ランニングソーなどを用いて、第６図に示す
ように第２のパーティクルボード６に切削加工を施し、
多数の櫛歯状部分９を形成する。At this time, the back surface of the second particle board 6 is slightly smaller than the back surface of the first particle board 4 (approximately 0.3~
0.6T$L), stack them in multiple layers with the metal patch plate 7 and cushion rubber 8 sandwiched between them as shown in Fig. 5, and adhere them by applying pressure P from both sides. . In this way, the deformation of the cushion rubber 8 applies appropriate pressure to the second vertecle hoard 6, and the metal cover plate 7 also allows the decorative sheet 53 to be
Since only the part of the particle board 6 can be prevented from protruding, the entire decorative board can be made beautiful. On the other hand, if the second particle board 6 is made to protrude from the first particle board 4, too much pressure will be applied to the second particle board 6 during pressing, and the second particle board 6 will not be formed on the decorative sheet 5. This is not desirable because it causes Next, using a multi-axis running saw with a plurality of rotary saws arranged in parallel, the second particle board 6 is cut as shown in FIG.
A large number of comb-like portions 9 are formed.
このとき、櫛歯状の溝は、７第２のパーティクルボード
６をその厚み方向に貫通し、さらに第１のパーティクル
ボード４の残り厚み４ａ″の一部に至るまで切込む。ま

状部分９が互に接するように第１のパーティクルボード
４を折り曲け、接着固化させると、曲面を有する化粧板
か門完成する。At this time, the comb-shaped grooves pass through the second particle board 6 in its thickness direction and are further cut into a part of the remaining thickness 4a'' of the first particle board 4. Make sure that parts 6a, 6a of the second particle board 6 remain on both sides.In this way, the rough chips in the middle layer 4c of the first particle board 4 will not collapse. As shown in FIG. 7, the first particle board 4 is bent so that the comb-like portions 9 are in contact with each other, and then bonded and solidified to complete a decorative board or gate having a curved surface.
このように本発明は、板材として安価な第１のパーティ
クルボードを用い、曲面を付与する部分にのみ切削加工
に適する第２のパーティクルボードを用いるようにした
ものであるから、精度のよい化粧板を安価に構成するこ
とができる。In this way, the present invention uses the first particle board, which is inexpensive, as the board material, and uses the second particle board, which is suitable for cutting, only in the portion where a curved surface is to be provided, so that it is possible to create a highly accurate decorative board. can be constructed at low cost.
また、板材がすべてパーティクルボードで形成されるた
め、積層合板を用いたときのような目やせも発生せず、
しかも化粧シートの内面に表層の一部を残しているから
、第１、第２のパーティクルボードの継ぎ目が化粧シー
トに現われるのを防止することができ、さらに、凹部の
両側面に第２のパーティクルボードの一部を残すように
しているから、第１のパーティクルボードの中層が崩れ
るのを防止できるなどの優れた効果が得られる。In addition, since all the board materials are made of particle board, there is no visual loss that occurs when using laminated plywood.
Moreover, since a part of the surface layer is left on the inner surface of the decorative sheet, it is possible to prevent the seam between the first and second particle boards from appearing on the decorative sheet, and furthermore, the second particle board can be prevented from appearing on the decorative sheet on both sides of the recess. Since a part of the board is left, excellent effects such as preventing the middle layer of the first particle board from collapsing can be obtained.
