模様の広幅単板を、０．５ｍｍ以上の厚さの厚単板を用
いて製造する方法に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for manufacturing wide veneers by bonding veneers together, and particularly relates to a method for manufacturing a wide veneer by bonding veneers together, and in particular, for manufacturing natural wood decorative materials used for flooring, wall materials, etc. The present invention relates to a method for producing a wide veneer with a parquet pattern used as a surface decorative material for plywood using a thick veneer having a thickness of 0.5 mm or more.
［従来技術及びその問題点コ

このように接合された単板（１）相互をテープ（２ンで
一枚一枚繋ぎ合わせ、所定の大きさになった広幅単板を
製造するようにしていた。[Prior art and its problems] Conventionally, when manufacturing a wide veneer with a marquetry pattern using a thick veneer with a thickness of 0.5 mm or more, the veneer (1 ) by joining the veneers (1,) to each other at the end surface (la) or its end surface (1b),
The thus-joined veneers (1) were connected one by one with tape (2 tapes) to produce a wide veneer of a predetermined size.
しかし、このようにして広幅単板を製造する場合、その
製造を機械化すること、が困難であり、このため、従来
においては、通常、人が手作業により、単板（１）相互

テープ（２）によって単板（１）相互を一枚一枚繋ぎ合
わせるようになっており、非常に手間がかかり、生産効
率が著しく低いという問題があった。However, when producing wide veneers in this way, it is difficult to mechanize the production, and for this reason, in the past, people usually manually attached the veneers (1) to each other at the ends of their ends. Joined at the surface (1a) or end surface (1b),
The veneers (1) are connected one by one using tape (2), which is very time consuming and has the problem of extremely low production efficiency.
また、このように単板（１）相互をテープ（２）だけで
繋ぎ合わせて広幅単板を製造した場合、これを持ち上げ
て運ぶ際等に、テープ（２）が伸びて単板（１）間に隙
間が生じたり、テープ（２）が破れて単板（１）相互が
外れたりするという問題もあった。In addition, if a wide veneer is manufactured by joining the veneers (1) together with only the tape (2) in this way, the tape (2) may stretch when the veneer (1) is lifted and transported. There were also problems in that gaps were created between the two, and the tape (2) was torn and the veneers (1) were separated from each other.
ここで、このような広幅単板の製造を機械化させるため

行い、単板列（１０）相互をテープ（２）によって連続
して接合させて、広幅単板を製造することを考え付いた
。Here, in order to mechanize the production of such wide veneers, the inventor joined the end surfaces (1a) of the veneers (1) to each other, as shown in FIG. Taping is done from the back side of (1), and the veneers (1,) are vertically joined with tape (2) to form a row of veneers (lO) of the required length.
After forming the veneer rows (10), the veneer rows (10) are arranged one after another in the width direction, taping is performed from the back side of the veneer rows (10), and the veneer rows (10) are connected to each other with tape (2). He came up with the idea of manufacturing wide veneers by joining them together.
しかし、このように単板（１）相互の縦継ぎ及び単板列

くなるという問題が生じた。However, when the veneers (1) are vertically joined together and the veneer rows (lO) are joined together using tape (2), as shown in the figure, the veneers (1) are joined vertically to each other. The tape (2) used for splicing and the tape (2) used to join the veneer rows (lO) partially overlap, and this wide veneer is attached to the surface of the board to create a natural marquetry pattern. When producing decorative wood plywood, a problem arose in that the above-mentioned molded part became high and could not be properly attached to the substrate, resulting in poor finish of the decorative natural wood plywood.

After applying a rubber adhesive to the butt sides (1a) of each veneer (1) to be joined, a longitudinal splicing machine is used to join the veneers (1) together on their butt sides (1a) as shown in Figure 2. The veneers are vertically spliced one after another in order to form a row of veneers (10) of a required length.

In order to change the width for each row of boards (10), or to make sure that the width of each veneer (1) is constant, each veneer (1) is cut accurately in advance, and then used for guillotine or running. It is also possible to omit cutting the width of the row of veneers (10) with a saw.

によって連続して行うことができる。ようになった。[Effects of the Invention] As detailed above, in the wide veneer manufacturing method according to the present invention, the veneers are vertically spliced at their butt sides with adhesive to form rows of veneers of a required length. Because I did it like this,
It has become possible to apply adhesive to the butt side of the veneers using a sprayer or a vertical gluing machine, and to vertically join the veneers together using a vertical splicing machine. The veneer rows are lined up one after another in the width direction, taped from one side, and the veneer rows are successively joined with tape, making it possible to join the veneer rows together successively using a taping machine, etc. can. It became so.
この結果、広幅単板の製造全体を機械化して行うことが
できるようになり、広幅単板の生産効率が著しく向上す
るようになった。As a result, it has become possible to mechanize the entire production of wide veneers, and the production efficiency of wide veneers has been significantly improved.
また、単板相互を縦継ぎして所要長さの単板列を形成す
るにあたり、単板相互の木口面を接着剤によって接合さ
せるようにしたため、このようにして形成された単板列
にテーピングを行い、テープによって単板列相互を接合
させた場合においても、従来のようにテープ相互が重な
り合うということがなくなった。In addition, when veneers are vertically spliced to form rows of veneers of the required length, the end surfaces of each veneer are joined with adhesive, so taping is applied to the rows of veneers formed in this way. Even when veneer rows are joined together using tape, the tapes no longer overlap each other as in the past.
このため、このようにして製造された広幅単板を表面化

た天然木化粧合板を製造できるようになった。For this reason, when using the wide veneer manufactured in this way as a decorative surface material and attaching it to the surface of a substrate to manufacture decorative natural wood plywood, it will not work like a conventional wide veneer. It is possible to produce natural wood decorative plywood in which the wide veneer is neatly adhered to the substrate surface, without the tapes overlapping each other and not adhering properly to the substrate surface, resulting in poor finish of the natural wood decorative plywood. It became so.
