Description
(a)アンビルロール及びパターンロールが相互に逆回転でき、該アンビルロールがアンビルロール外側表面を有し、該パターンロールがパターンロール外側表面を有し、少なくとも1つの荷重受け台部材が該パターンロール外側表面と該アンビルロール外側表面との間に配置され、該荷重受け台部材が受け台の高さを有し、少なくとも1つのパターン要素が該パターンロールの外側表面から伸び、該パターン要素がパターンの高さを有し、該受け台の高さが該パターンの高さより高く、該パターン要素と該アンビルロールの外側表面との間に無荷重間隙を生じさせる、アンビルロール及びパターンロールを準備する工程;
(b)前記パターン要素と前記アンビルロールの外側表面との間に静的荷重間隙を生じさせ、該静的荷重間隙が前記無荷重間隙より小さくなるように荷重力を供給して該ロールを互いに押し合わせる工程;
(c)パターンロールの外側表面とアンビルロールの外側表面との間に積層体を供給する工程と;
(d)結合するロールをある接線速度で回転させて、パターン要素とアンビルロールの外側表面との間で積層体を圧縮して、積層体の結合させる工程とを含む。
(1)不適合な材料を粒子状物質に形成する。
C.不適合な材料を結合する(及び成形する)。
図8は、覆い材料24の第1部分24Aが、好ましくは、管形成複合ウェブ88を通って覆い材料の第2部分24Bまで結合されるプロセスを示している。管形成複合ウェブ88を結合するために使用される装置は、好ましくは、1対の円筒形のロール110、112を含む。好ましくは、ロールの少なくともひとつ、パターンのあるロール110は、その表面上にレリーフパターンを有する。パターンのあるロール110は、図8では簡略化した手法で示され、図12で更に詳細に示される。(しかし、図12は、図8に示すパターンと僅かに異なるレリーフパターンをその上に有するロールを示している。)
図12に示すように、パターンのあるロール110は、円筒形の表面115と、表面115から外側に伸びる複数の突起又はパターン要素(又は「パターン要素区分」、「突出物」、若しくは「ネップ(nub)」)116とを有する。パターン要素116により形成されるレリーフパターンは、いかなる好適な形体であり得る。それは、線状であっても、曲線状であってもよく、又は線状の区分及び曲線状の区分から成ってもよい。レリーフパターンは連続的であることも、断続的であることもできる。レリーフパターンは、非限定数のパターン及び他のタイプのデザインを画定することができる。例えば、幾何学的な形、矢印、言葉などを画定してもよい。パターン要素上のランド表面118も、多種多様の可能な形で設けることができる。ランド表面118に好適な形には、楕円形及び円形が挙げられるが、これらに限定されない。
対応しやすい材料120は、いかなる好適な種類の材料を含むことができる。好適な材料には、真鍮、ゴム、及びポリウレタンなどの高分子材料が挙げられる。特に好ましい実施形態では、対応しやすい材料120はポリウレタンを含む。
連続する荷重受け部材の高さがパターン要素の高さより高いとき、また荷重受け部材が圧縮状態であるとき、上述の、パターンロールのパターン要素の「釣り合いを保つこと」は必要でなくなることが、驚くべきことに出願人により発見された。「釣り合いを保つ」ことを取り除くと、本発明の結合装置の製造における実質的な経費削減をもたらすだけでなく、結合パターンの設計における制限も取り除き、その結果、溶融結合を利用する製品の設計に更に大きな機会をもたらす。
本発明の特定の実施形態を例示し記載したが、本発明の精神及び範囲から逸脱することなく他の様々な変更及び修正を実施できることが、当業者には明らかであろう。
