【従来の技術】
複数の極薄状突板を一列に接続して形成した連続状突板の裏面に、不織紙等からなる連続状裏貼りシートを単一又は複数枚接合してなる多層木質テープは公知である。 0002.
[Conventional technology]
A multilayer wood tape in which a single or a plurality of continuous backing sheets made of non-woven paper or the like are joined to the back surface of a continuous veneer formed by connecting a plurality of ultrathin veneers in a row is known.

この木質テープは、図２で示すように、例えば、集成材からなる階段等の基材ｘの端縁を被覆して、あたかも銘木による一枚板であるかのような外観を呈するようにする等、仕上材，補修材として用いられる。ところで、基材ｘの被着面は、表面に凹凸があり、薄い木質テープであると、その凹凸がテープ表面にも表れてしまい、このため、厚肉のテープが求められている。また、同図で示すように、階段の前縁に接合された木質テープは面取りｙが行われ、このため、同様に、厚肉である必要があり、しかもに、切断面が周囲の木質面と違和感があるものであってはならない。 As shown in FIG. 2 , this wood tape covers the edge of the base material x such as a staircase made of laminated wood so as to give an appearance as if it were a single plate made of wood. Etc., used as finishing material and repair material. By the way, the adherend surface of the base material x has irregularities on the surface, and if the thin wood tape is used, the irregularities also appear on the tape surface, and therefore, a thick tape is required. Further, as shown in the figure, the wood tape joined to the front edge of the stairs is chamfered, so that it also needs to be thick, and the cut surface is the surrounding wood surface. It should not be uncomfortable.

[Means for solving problems]
In the present invention, a continuous resin sheet made of non-woven paper is bonded to the back surface of a continuous veneer in which a plurality of ultra-thin veneers are connected in a row, and the continuous resin sheet is made of non-woven paper. It is a multi-layer wood tape characterized by being impregnated with a resin. Further, the present invention is characterized in that two or more layers of continuous resin sheets formed by impregnating non-woven paper with resin are bonded to the back surface of continuous veneers in which a plurality of ultrathin veneers are connected in a row. It is a multi-layer wood tape.

かかる構成の多層木質テープにあっては、
連続状樹脂シートを引張状態で走行させ、その上面に接着剤を塗布するとともに、上方から前記連続状突板を供給し、その裏面を前記接着剤の塗布面に重ね合わせて、連続状突板を連続状樹脂シートに接合して表面側二層シートを形成する第一工程と、
二枚の連続状樹脂シートを接合して基部側二層シートを形成する第二工程と、表面側二層シートの下面に一又は複数の基部側二層シートを接合する第三工程とを順次行うことにより良好に製造することができる。 In the case of multi-layer wood tape with such a configuration,
The continuous resin sheet is run in a tension state, the adhesive is applied to the upper surface thereof, the continuous veneer is supplied from above, and the back surface thereof is overlapped with the coated surface of the adhesive to continuously form the continuous veneer. The first step of joining to a resin sheet to form a two-layer sheet on the surface side,
The second step of joining two continuous resin sheets to form a base-side two-layer sheet and the third step of joining one or more base-side two-layer sheets to the lower surface of the front-side two-layer sheet are sequentially performed. By doing so, it can be manufactured satisfactorily.

また、連続状樹脂シート４を、薄茶色等の木色系の着色樹脂シートとすることができ、この場合には、上述した図２のように面取りｙにより切断面が露出する場合に、その切断面に木質感を生じさせることが可能となり、さらに良好な仕上材となる。 Further, the continuous resin sheet 4 can be a wood-colored colored resin sheet such as light brown, and in this case, when the cut surface is exposed by chamfering y as shown in FIG. 2 described above, the continuous resin sheet 4 can be used. It is possible to give a wood texture to the cut surface, resulting in a better finishing material.

【発明の効果】
本発明は上述のように、連続状突板の裏面に、不織紙に樹脂を含浸してなる連続状樹脂シートを接合してなるものであるから、十分な厚さの仕上材を形成できる。また連続状樹脂シートを二層以上接合してなるものにあっては、複数枚の、凹凸がある基材の被貼着面に貼着した場合に、該凹凸が吸収され、貼着後の表面を平滑とすることができ、しかも連続状樹脂シートの調製により、固さや，柔軟性も最適なものとすることができて、用途に応じた最適な特性を備えるものに調整することが容易となり、ロールから巻き戻しても、巻き癖がつきにくく、基材に貼りつけるに際に、作業性が良い。また、天然の銘木を多数用いるものとは異なり、単価が安く、加工が簡単で、ヒビ割れの発生，接合不良等に生じにくく、不良品の発生率が低い。しかも、切断面でササクレが無く、施工時の後加工が容易である。 0034
【Effect of the invention】
As described above, the present invention is formed by joining a continuous resin sheet obtained by impregnating non-woven paper with resin to the back surface of the continuous veneer, so that a finishing material having a sufficient thickness can be formed. Further, in the case of a continuous resin sheet in which two or more layers are bonded, when a plurality of sheets are attached to the surface to be adhered to a base material having irregularities, the irregularities are absorbed and after the attachment, the irregularities are absorbed. The surface can be smoothed, and by preparing a continuous resin sheet, the hardness and flexibility can be optimized, and it is easy to adjust to those having the optimum characteristics according to the application. Therefore, even if it is rewound from the roll, it does not easily have a curl, and it has good workability when it is attached to the base material. In addition, unlike those using a large number of natural name wood, the unit price is low, processing is easy, cracks are less likely to occur, joint defects, etc. are less likely to occur, and the incidence of defective products is low. Moreover, there is no hangnail on the cut surface, and post-processing during construction is easy.

また、連続状樹脂シート４を、薄茶色等の木色系の着色樹脂シートとすることができ、この場合には、上述した図２のように面取りｙにより切断面が露出する場合に、その切断面に木質感を生じさせることが可能となる。 Further, the continuous resin sheet 4 can be a wood-colored colored resin sheet such as light brown, and in this case, when the cut surface is exposed by chamfering y as shown in FIG. 2 described above, the continuous resin sheet 4 can be used. It is possible to give a wood texture to the cut surface.

さらに、連続状樹脂シートを引張状態で走行させ、その上面に接着剤を塗布するとともに、上方から前記連続状突板を供給し、その裏面を前記接着剤の塗布面に重ね合わせて、連続状突板を連続状樹脂シートに接合して表面側二層シートを形成する第一工程を備えた上述の多層木質テープ製造方法にあっては、引張状態で走行させた連続状樹脂シート上に、接着剤を塗布するものであるから、該連続状樹脂シートが均一厚であるため、接着剤の供給量が安定し、しかも塗布した接着剤が殆ど吸収されず、塗布むらが生じることがなく、接合強度が向上し、接着剤を節約することができる。また、連続状樹脂シートを走行させるものであるため、連続状突板の突き合わせ部に引張力が作用せず、走行速度を速くしても、該突き合わせ部に隙間が生じることがなく、さらに、連続状樹脂シートが均一厚であるため、蛇行することもなく、生産効率を向上させることができる。 Further, the continuous resin sheet is run in a tension state, the adhesive is applied to the upper surface thereof, the continuous veneer is supplied from above, and the back surface thereof is overlapped with the coated surface of the adhesive to superimpose the continuous veneer on the coated surface of the adhesive. In the above-mentioned method for producing a multi-layer wood tape including a first step of forming a surface-side two-layer sheet by joining the adhesive to a continuous resin sheet, an adhesive is applied onto the continuous resin sheet that has been run in a tensile state. Since the continuous resin sheet has a uniform thickness, the supply amount of the adhesive is stable, the applied adhesive is hardly absorbed, uneven coating does not occur, and the bonding strength is reduced. Can be improved and the adhesive can be saved. Further, since the continuous resin sheet is run, no tensile force acts on the butt portion of the continuous veneer, and even if the running speed is increased, no gap is generated in the butt portion, and further, it is continuous. Since the resin sheet has a uniform thickness, it does not meander and production efficiency can be improved.
