【発明の詳細な説明】 産業上の利用分野 この発明は、建築物の壁面内装材、天井材等に使用され
る溝付き化粧板の製造方法に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a grooved decorative plate used for wall interior materials, ceiling materials, etc. of buildings.
従来の技術と問題点 主に壁面内装用に用いられるような化粧板として、表面
に多数の平行する細い溝を形成することにより、立体感
を付与し意匠性の向上をはかった溝付き化粧板が多く用
いられている。Conventional technology and problems As a decorative plate that is mainly used for interior wall surfaces, a grooved decorative plate that has a three-dimensional effect and is improved in design by forming a number of parallel thin grooves on the surface. Is often used.
かゝる溝付き化粧板は、従来最も一般的には切削加工に
よって表面に溝を削成することによって製造されてい
た。ところがこの場合、切削後の溝内面の仕上りに難点
があるところから、近時、溝の内面に表面の化粧層を連
続状に存在せしめたものとする溝付き化粧板の製造方法
が種々提案されている。Such grooved decorative boards have hitherto been most commonly manufactured by cutting grooves on the surface by cutting. However, in this case, since there is a difficulty in finishing the inner surface of the groove after cutting, recently, various methods for producing a grooved decorative plate in which a surface decorative layer is continuously present on the inner surface of the groove have been proposed. ing.

その幅寸法に相当厳密な精度が要求されるため、実際上
工業的生産には不向きであり、コスト高につくという根
本的な問題点を有している。One of the prior proposal techniques is, as seen in Japanese Utility Model Publication No. 59-1765, after the V groove is formed on the required substrate surface,
After sticking a wood veneer for makeup on the flat surface between each V groove with the side edges protruding in an overlapping manner on the groove, fold the above side edges of this veneer to both side surfaces of the V groove. It is to be attached. However, according to this method, a large number of individual decorative veneers that are independent of each other depending on the number of decorative grooves are required, and they must be individually arranged and adhered on the substrate in an accurate arrangement. In addition, each makeup veneer itself,
Since the width dimension requires a considerably strict accuracy, it is practically unsuitable for industrial production and has a fundamental problem that the cost becomes high.

くることができず、十分に立体感に富む化粧板を提供す
ることができないという別の問題点があった。Further, as another prior proposal technique, in Japanese Patent Laid-Open No. 61-29541, after a decorative sheet is attached to a substrate, the plate surface is fixed with an embossing roll or an embossing plate having an embossing ridge having a V-shaped cross section. A method has been proposed in which a narrow groove corresponding to the above-mentioned ridge is press-fitted by pressing. However,
In the case of this method, it is necessary not to break the decorative sheet in the portion where the cosmetic groove is formed, and since the embossing is performed on the premise of that, the depth of the furrow groove is 0.4 mm to at most 0.6 mm. There is another problem that it is impossible to provide a decorative plate having a sufficient three-dimensional effect because the decorative plate cannot be made extremely shallow.

しうるようにしたものである。Means for Solving the Problems The present invention uses the technique of embossing to form grooves,
Contrary to the conventional idea, rather conversely, by cutting the decorative sheet on the surface straight in the central part of the groove, by covering it only on both upper side surfaces of the groove,
By exposing the substrate material to the inner surface of the lower portion of the groove while allowing the formation of a sufficiently deep groove, other secondary advantages can be enjoyed.

Is heated and pressed by using an embossing plate (10) or an embossing roll having a press-fitting ridge (9) having a substantially V-shaped cross section at a position corresponding to. By this heat embossing, the decorative sheet (4)
Both sides of the notch (6) are pushed into the groove (2) of the substrate (1), and the upper portions of both side walls are covered, and the base material of the substrate (1) is provided on the surface of the decorative plate (A) and the lower inner surface of the groove. The decorative groove (11) having a substantially V-shaped cross-section exposed is formed, and at the same time, the adhesive (3) is heat-cured to completely bond the decorative sheet (4) to the substrate (1). The embossing board (10)
Alternatively, the press-fitting ridge (9) of the embossing roll is the substrate (1).
Use a groove slightly larger than the V-shaped groove (2), and press-fit the convex shape (9) to enlarge the groove (2) and compress the groove wall portion to form the decorative groove (11) as desired. It shall be shaped into a shape and its surface shall be finished in a smooth state.
For example, as shown in FIG. 5, the width (W1) and height (h1) of the press-fitting ridge (9) are set to the width (W2) and height (h2) of the groove (2) on the substrate (1) side. ) Are both larger than
In addition, the V-shaped cross-section whose tip is an acute angle and whose both sides are gently curved inward is forcibly pressed into the groove to form the decorative groove (11) as shown in FIG. It should be formed in a shape corresponding to (9). In this case, since the texture of the substrate (1) should not be destroyed by the press-fitting of the ridges (9), it is necessary to use a wood material for the substrate (1). The use of inorganic plates such as plates is unsuitable.

し、両者を共に加熱するものとしても良い。For heating during embossing, the decorative sheet (4) is applied to the substrate (1).
This is done in order to improve the shaping stability of the decorative groove (11) at the same time. The temperature and the embossing time are appropriately set according to the type and specific gravity of the substrate (1), the type of decorative sheet (4), the type of adhesive, etc., but generally, the temperature is 70 to 300 ° C and the time is 1 hour. It can be set within the range of about 10 minutes. In addition, the above heating is applied to the decorative plate (A)
Either one of the mold and the die may be heated, or both may be heated together.

剤を塗布する。By the way, in the embossing process, the folded portion (4a) of the decorative sheet (4) into the groove (2) must be bonded and fixed to the substrate (1) side at the same time. Therefore, it is necessary to apply the adhesive into the groove (2) at the stage of applying the adhesive (3). Such application of the adhesive (3) may be carried out by a method of simultaneously applying the adhesive on the surface of the substrate (1) including the groove bottom portion in the groove (2) by spraying. Since the adhesive does not require an adhesive, it is desirable to perform it by the following method using a spreader. That is, one method is
The spacing between the soft spreader roll and the feed roll of the spreader is set to be much smaller than the thickness of the decorative plate (A), so that the upper edge of the side surface of the groove (2) is first set as shown in FIG. 8 (a). Apply adhesive. At this stage, the amount of adhesive applied to the surface portion of the substrate (1) is insufficient. Therefore, next, the gap between the coating roll and the feed roll is slightly widened, and the second coating work is performed to correspond to the thickness of the decorative plate, and as shown in FIG. Apply the required amount of adhesive.

Apply a large amount of adhesive in a slight excess on the surface of.
Then, as shown in FIG. 9 (a), the adhesive (3) is in a slightly raised state on the edge of the groove (2. Therefore, when the decorative sheets (4) are stacked and pressed with a roll or the like. It is possible to realize a state in which the raised adhesive flows into the side surface of the groove (2) as shown in FIG. 9 (b) and the adhesive is applied to both upper side surfaces of the groove (2). it can.

Is 3.0 mm or more and the depth (D) is 2.5 mm or more.
Particularly preferably, the width (W3) is 5 to 10 mm and the depth (D) is 3 to
It should be formed to a thickness of about 5 mm. For example, in a decorative board (A) in which a wood veneer (4) of 0.2 mm is attached to an MDF substrate (1) having a thickness of 5 mm, the width (W3) is 7.0 mm and the depth ( D) When the 3.5 mm decorative grooves (11) as shown in Fig. 5 are formed at intervals of 2.0 cm, the decorative plate (A) is slightly flexible while imparting an excellent three-dimensional effect to the surface. It is possible to give a product that can be applied and can be applied to a curved surface. It should be noted that the interval between the decorative grooves (11), that is, the pitch, is of course arbitrary and is not limited at all.

Since the decorative groove is formed, it is possible to form the decorative groove sufficiently deep and wide, and it is possible to obtain a grooved decorative plate in which the existence of the decorative groove is sufficiently emphasized on the plate surface. . In addition, the decorative groove is formed by cutting the decorative sheet on the surface of the decorative plate, and then using a die-pressing plate or an embossing roll having a press-fitting convex portion having a substantially V-shaped cross section, by embossing the convex portion. Since the corresponding shape is formed in a substantially V-shaped cross section, the decorative sheet does not break or crack during embossing, and the top side of the decorative groove is a clean and continuous folded portion of the decorative sheet. Will be covered with. Therefore, the thin decorative sheet does not appear in the decorative groove portion. In addition, the decorative groove is formed in a substantially V-shaped cross-section with the tip having an acute angle and both side surfaces gently curved inward, so that the thickness of the decorative sheet does not appear in the groove portion as described above. Combined with this, it is possible to make it look and feel high-grade as if thick veneer veneer or solid wood is used.
