Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a continuous wood board sheet, more specifically, a continuous wood board formed by connecting a plurality of wood board sheets lined with a flexible sheet material. Regarding the seat.

<Prior Art> JP-A-57-151367 discloses a flexible veneer composed of a plurality of veneer leaves lined with a flexible non-woven fabric, and the ends of each veneer leaf are connected via finger joints. It is shown. This flexible veneer forms a finger pattern on two opposing ends of each non-woven lined veneer leaf,
It is obtained by bonding the fingers together while applying the adhesive in the seam.

In Japanese Utility Model Laid-Open No. 61-74433, a printed pattern is formed on the front surface of the wood board sheet, and a fibrous backing sheet is laminated on the back surface of the wood board sheet with an adhesive layer interposed therebetween. A snowboard decorative sheet is shown. The glazed board sheet in this glazed board decorative sheet may be made long by joining two glove board sheets via corresponding finger joint portions, as shown in FIG. 3 of the publication. . On the back side of the finger joint part, an adhesive tape coated with a hot melt adhesive or the like is adhered. By thus lengthening and winding up the wood plate sheet, various processes are continuously performed. It is described that there is an advantage that it can be performed (Specification page 4, lines 4 to 12).

<Problems to be Solved by the Invention> When the finger parts of the veneer leaf ends of the former flexible veneer are bonded together, the adhesive is applied in the joints, so that the finger parts are strong. A bond is obtained. However, the strength at the joint is greater than the strength of the veneer leaf itself, and the joint made of cured adhesive is not flexible.
For this reason, the veneer is broken near the joint portion when it is attached to the bending material, and there is a drawback that the characteristics of the "flexible veneer" cannot be fully exhibited. In addition, the strength and strength of the veneer joint and the veneer leaf body are
Due to the difference in hardness, when the veneer surface is sanded, the amount of polishing in the bonded portion is small and the amount of polishing in the main portion of the veneer leaf is large, which makes it difficult to obtain a smooth surface as a whole.

Further, in the latter case, when a skin board decorative sheet is obtained by using a long wood board sheet as described in FIG. 3 of the publication, the presence of the adhesive tape adhered to the back side of the finger joint causes 0.4mm because the surface corresponding to the tape is slightly raised and the sand plate of that part is greatly polished during sanding.
It could not be used in the case of the following thin wood plates.

<Means for Solving the Problems> The present invention has been devised to solve the problems encountered in the above-mentioned prior art, and is a luck board sheet formed by backing a flexible sheet material. , A plurality of wood board sheets are finger-jointed at the fiber direction end of the surface wood board, and an adhesive tape is adhered on the wood board surface of each finger joint part. It is a wood board sheet.

The wood board used for the continuous wood board sheet of this invention is
It can be obtained by cutting raw wood or flitch made of wood such as cedar, pine, toga, cypress, agatis and chestnut with a cutting device such as a rotary race, a half rotary race and a slicer.

A flexible sheet material is attached as a backing material to the back surface of the wood board with an adhesive. Washi, non-woven fabric, synthetic fiber paper, scientific fiber paper and the like are preferably used as the flexible sheet material. As the adhesive, synthetic resin adhesive such as urea resin, urethane resin, epoxy resin, melamine resin, isocyanate, vinyl acetate resin or modified resin thereof is preferably used. For sticking, apply a glue to a wide flexible sheet material and then lay out a wood board, or apply a glue to a continuous sheet material and then arrange a wood board continuously to form a long sheet. And, it is pressure-bonded by a pressure device such as cold press, hot press, roll press, etc.,
Instead of applying the adhesive to the sheet material, the adhesive may be applied to the back surface of the skid board, or the adhesive may be applied to both the sheet material and the back surface of the skid board.

After sticking the sheet-like material and the luck board, it is cut according to the size of the luck board to obtain a luck board sheet in which a flexible sheet-like material is lined.

The obtained lumber board sheet is thrown into a cutting device, and finger patterns are formed in the fiber-direction openings of the lumber board.

Next, finger patterns are formed by fitting the finger patterns formed at the respective mouths of the wood board sheet, and at the same time, an adhesive tape is attached on the wood board surface of the finger joint portion to form a plurality of wood boards. By connecting the plate sheets, the present invention provides a continuous wood plate sheet.

Adhesive tapes are Japanese paper, kraft paper, crepe paper, rope paper, non-woven fabric, cotton cloth, human cotton, Tetoron cloth, acetate cloth,
At least one side of flexible support such as glass cloth, natural rubber sheet, synthetic rubber sheet, polyester film, polyethylene film, polypropylene film, acetate film, cellophane, and various papers, cloth, rubber sheet, plastic film, etc. An adhesive substance such as a pressure-sensitive adhesive, a hot melt adhesive, a water-soluble adhesive, and a rewetting paste is applied to the above.

When a continuous luck board sheet is obtained in a long shape, it can be wound up on a roll to obtain a luck board sheet roll, if necessary.

The obtained continuous wood board sheet is continuously adhered to the surface of a building member, a furniture member or the like or the surface of a bending member via an adhesive, and then cut according to the shape of the base material. In addition, by sanding the surface of the wood board after sticking,
The adhesive tape attached to the surface of the skid plate in the finger joint is ground and removed, and the surface of the skid plate is further ground as necessary. If necessary, the surface of the wood plate after the grinding process is painted.

<Embodiment> A continuous wood board sheet 1 according to an embodiment of the present invention shown in the drawings has a backing sheet 2 which is a flexible sheet-like material and an adhesive layer 3 interposed between the wood board sheets 4 and 4. ′ Is bonded while being finger-jointed by the fitting of the finger portions 5 and 5 ′ formed at the end of the mouth in the fiber direction X, and further flexible across the wood plate sheets 4 and 4 ′ in this finger joint portion. Adhesive tape 6 is attached.

<Effect of the device> In the continuous wood board sheet according to the present invention, since the finger joint is formed at the fiber end of the wood board, it is possible to avoid missing or breaking of the finger part even with a thin and long finger pattern. In addition, firm finger-fitting is performed, and the joint in the joint is substantially in parallel with the flow in the fiber direction so that it is not noticeable and contributes to the improvement of design. An adhesive tape is attached on the surface of the fingerboard in the finger joint, and this adhesive tape provides sufficient flexibility in the finger joint, so that the continuous sheet of continuous wood obtained in a long shape is wound on a roll. Even when using a skid sheet roll, the finger joints will not be disengaged or the mouth will not open. Sufficient flexibility in the finger joint portion allows the wood board sheet to be attached to the bending member and facilitates handling.
Also, it prevents the occurrence of cracks and chips at the mouth of the wood board sheet.
