【０００１】
【発明の属する技術分野】
本発明は、建築物の床材等内装材に用いるに好適な化粧板の製造方法に関する。
【０００２】
【従来の技術】
従来から、合板、ＬＶＬ、ＭＤＦ等の繊維板、ウェハーボード、パーティクルボード、或いはそれらの組み合わせからなる複合板等の木質基板の表面に、木質化粧単板、合成樹脂化粧シート、樹脂含浸化粧紙、樹脂コート化粧印刷紙などの化粧シート材を貼着した化粧板は良く知られている。また、このような化粧板には、化粧板同士の継ぎ目部を目立たなくしたり、その装飾性を向上させるために、表面にＶ状、凹状、Ｕ状、或いは曲面状等の化粧溝加工を施すことも良く知られている。
【０００３】
【発明が解決しようとする課題】
このような溝付き化粧板は、通常、基板の表面に化粧シート材を貼着した後、その表面に切削手段により化粧溝加工が施されているが、化粧溝内面に切削による粗面が露出したり、化粧シート材の色調と異なる基板の色調が表面に露出し、化粧外観を損ねることがあるという欠点があった。また、上記化粧溝内面の装飾性を向上させるために、化粧溝内面に着色塗装を施すことも行なわれているが、塗料ムラや塗料の染み込みムラが生じ易いという欠点を有していた。
【０００４】
このため、例えば特開昭６１−２９５４１号に記載されているように、基板表面に化粧シート材を接着し、この表面に各種塗装を施したのち、型材で押圧して化粧溝を形成したり、或いは、特公平７−１０２５３４号に記載されているように、木質基板の表面に切削により溝加工を施し、この表面に木質単板からなる化粧シート材を重ねて仮着し、溝の上の化粧シート材に切目を入れてから、型材で押圧することにより化粧シート材を基板に接着させる方法が提案されている。
【０００５】
しかしながら、上記前者の方法では極小さな細溝を形成することはできるが、通常の大きさの化粧溝を形成しようとすると、押圧により化粧シート材が破損したり、化粧溝形成後において木質基板の復元力により元に戻ろうとするため、化粧溝形状が不均一となって、かえって生産性や装飾性を低下させるという問題があった。
【０００６】
また、上記後者の方法によると、切目を正確に入れないと化粧外観が却って悪くなるという生産技術上の課題を有するとともに、化粧シート材が、接着性の良くない化粧溝内面において非連続的に接着されることになるので、特に床材のように歩行等による摩擦の発生がある用途では、このような部分からの剥離等の損傷が生じ易いという危惧があった。
【０００７】
本発明は、かかる従来の欠点に鑑みなされたもので、良好な外観の化粧溝内面を有する化粧板を、生産性良く製造することのできる化粧板の製造方法を提供することを目的とする。
【０００８】
【課題を解決するための手段】
上記の目的を達成するため、請求項１の発明の化粧板の製造方法は、基板表面に接着剤を塗布した後、その接着剤が塗布された上記基板表面に化粧シート材を配し、次いで、縦溝形成用凸部を備えた型材で上記化粧シート材の表面を押圧することで、上記基板表面に、基板の互いに対向する側辺と平行でかつ該基板表面の全体に亘り連続して延びる複数の縦溝を形成すると同時に該縦溝を含む上記基板表面の全体に上記化粧シート材を接着し、引き続いて、横溝形成用凸部を備えた型材で上記化粧シート材表面を押圧することで、上記基板表面の上記隣り合う縦溝間又は上記縦溝と基板の上記対向する側辺との間に、縦溝と直角をなす方向に基板表面の全体で不連続に延びる複数の横溝を形成する構成とした。
【０００９】
これによれば、連続した化粧シート材を縦横の化粧溝を含む木質基板の表面全面に生産性良く接着させることができ、表面の平坦面だけでなく面取り加工面や化粧溝内面を化粧シート材によって、強固且つ良好に装飾した化粧板を得ることができる。
【００１０】
請求項２の発明の化粧板の製造方法は、請求項１に記載の発明において、基板表面において縦溝及び横溝が形成される位置に、該縦溝及び横溝の形成を円滑にしかつ縦溝及び横溝よりも小さい形状の一次加工溝が予め形成されている構成とした。
【００１１】
これによれば、型材による縦溝および横溝の形成を良好にすることができ、また深さのある縦溝や横溝の形成も容易に行なうことができる。
【００１２】
請求項３の発明の化粧板の製造方法は、請求項１又は２の発明において、基板の表面に該基板を長手方向に分割する２以上の切断用部が設けられており、横溝形成後に上記切断用部の央部から長手方向に２以上に切断する構成とした。
【００１３】
これによれば、一連の製造工程において、複数枚、即ち（切断用部の数＋１）枚の化粧板を一挙に加工することができ、上記請求項１の発明の作用効果に加えて、更に生産効率を向上させることができる。
