この発明は、基板表面に一本または複数本の平
行溝を形成し、この平行溝内を含む基板表面に沿
つてシートを接着した平行溝付化粧板の製造方法
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a decorative board with parallel grooves, in which one or more parallel grooves are formed on the surface of a substrate, and a sheet is adhered along the surface of the substrate including the inside of the parallel grooves. .
従来から市販されている平行溝付化粧板は、基

た。また、溝内に帯状の化粧シートを貼る技術も
公知であるが、この方法は極めて生産性が悪い欠
点があつた。 Conventionally, commercially available decorative boards with parallel grooves have been generally formed by forming parallel grooves after adhering a decorative sheet to the surface of the substrate, and then painting the inside of the grooves.
However, with this method, if there are cracks or irregularities within the grooves, the appearance will be poor even after painting, and the paint will also protrude outside the grooves, reducing the product value. Furthermore, a technique of pasting a band-shaped decorative sheet inside the groove is also known, but this method has the drawback of extremely low productivity.

を特徴とする平行溝付化粧板の製造方法に係る。 In order to solve the above-mentioned drawbacks, this invention attempts to adhere the sheet continuously even within the grooves. In other words, the invention attempts to adhere the sheet continuously even within the grooves. In other words, the sheet is bonded along the surface of the substrate in which one or more parallel grooves are formed. When bonding, an adhesive is applied to the surface of the substrate, the back surface of the sheet, or both, and the sheet corresponding to the part to be bonded in the groove is coated with a backing plate or a backing plate having a protrusion in the opposite shape to that of the groove. After using a roll to form a slack in a shape similar to the groove, the slack part of the sheet is first brought into contact with the groove using a groove presser roll, and then a smoothing roll or the like is used to form a slack in the shape of the substrate surface. The present invention relates to a method for producing a decorative board with parallel grooves, which is characterized by press-bonding the decorative board along its length.

溝付化粧板の一部切欠斜視図である。 FIG. 1 is a side view of an apparatus used to carry out the present invention, and FIG. 2 is a partial plan view of FIG. 1. An ethylene vinyl acetate resin adhesive 4 is applied to the back surface of the decorative PVC sheet 2 unwound from the rolled ball 1 using a coating machine 3 such as a roll coater. 5 is a drying device such as an infrared heater, which makes the adhesive 4 applied to the back side of the sheet semi-dry or dry to the touch, softens the decorative PVC sheet 2, and creates sag in the sheet 2 in a shape similar to the grooves 8. This makes it easier to form. In addition, if a method is adopted in which adhesive is applied to the surface of the plywood 7, the drying device is placed after the adhesive is applied. 6 is a backing plate, which has a convex shape opposite to that of the groove 8 formed on the surface of the plywood 7. It has a strip 9, and by feeding the sheet 2 along this patch plate 6,
A slack having a similar shape to the groove 8 is formed in the sheet 2. The backing plate 6 may be made of any material such as metal, synthetic resin, or wood, and has a curved surface that is curved toward the side that contacts the sheet 2 as shown in FIG. A protrusion 9 having a shape opposite to that of the groove 8 is formed on the groove 8 . Note that it is also possible to use a roll having protrusions on the circumferential surface instead of the backing plate 6. The sheet 2 with the slack formed is brought into contact with the surface of the plywood 7 in which one parallel groove is formed, which is conveyed by the feed roll 10 in the direction of the arrow a, and first the sheet is Press the slack part of 2 into the groove 8 of the plywood 7. Even if the groove presser roll 11 is a roll as shown in the figure,
Alternatively, it may be a thin roll that presses only the groove portion. Next, the sheet 2 is adhered to the surface of the plywood 7 using an ordinary smooth heat roll 12 heated to 50 to 80°C. This heat roll 12 may be a smooth roll, but the plywood 7
The roll may have protrusions on the circumferential surface of the portion corresponding to the grooves 8. Furthermore, as shown in the drawings, a roll 13 having protrusions on the circumferential surface may be disposed after the heat roll 12. The roll 13 itself may be heated, but hot air may be blown onto the sheet before the roll 13. Note that it is desirable that the groove presser roll 11 described above is placed in a process preceding the heat roll 12. This is because when the sheet 2 is thermocompression bonded to the flat surface of the plywood 7 and then pressed into the groove, only the slack part of the sheet 2 becomes the movable part when pressed into the groove, and the sheet 2
This is because if the sheet 2 attempts to move beyond the slack, there is a risk that the sheet 2 will be torn. If the sheet 2 is not thermocompression bonded to the flat part of the plywood 7, the sheet on the flat part can also be moved slightly, and the sheet 2 can be prevented from tearing. FIG. 4 is a partially cutaway perspective view of a decorative board with parallel grooves manufactured according to the present invention.
この発明は、上述したように構成されているの
で、以下に列記する効果を有する。 Since the present invention is configured as described above, it has the effects listed below.
シートにあらかじめ溝と類似の形状のたるみ
を形成した後、基板表面にまず、溝部押えロー
ルでシートのたるみ部分を溝内に当接している
ので、シートを基板の溝内面に無理なく密着さ
せて接着させることができ、シートが破れるこ
とは全くない。 After forming a slack in the sheet in advance in a shape similar to the groove, the slack part of the sheet is first brought into contact with the groove by a groove presser roll on the substrate surface, so that the sheet can be brought into close contact with the inner surface of the groove of the substrate without force. It can be glued and the sheet will not tear at all.
基板の平面部と溝内面とを一体連続したシー

麓な平行溝付化粧板を得ることができる。 To obtain a decorative plate with parallel grooves having an extremely beautiful surface without causing any problem even if the inner surface of the groove has cracks or irregularities by covering the flat part of the substrate and the inner surface of the groove with an integral continuous sheet. I can do it.
従来のように、溝内面を塗装したり、帯状の
化粧シートを貼る必要がなく、生産性が飛躍的
に向上する。 Unlike conventional methods, there is no need to paint the inner surface of the groove or apply a strip-shaped decorative sheet, dramatically improving productivity.
