Description
用語「有効ウェブ材料」が本明細書で利用されるが、その目的は、かかる有孔ウェブ材料から吸収性物品のための吸収性部材(又は非吸収性部材)等の構成要素を作成することである。そのような場合において、有孔ウェブ材料は、吸収性物品(例えばトップシート、バックシート、獲得層、吸収性コア)用に、個々の構成要素に切断される。吸収性物品に利用されるウェブの場合、そのような新しい構造体には、ウェブの既定の部分で、改善された性質(例えば改善された柔軟性、流体処理、又は他の性質等)を提供するものが含まれ得る。これらの有孔ウェブは、切断されて、包装(例えば、フローラップ、収縮包装、及びポリ袋など)、拭き取り用品、顔用ティッシュ、トイレットペーパー、ペーパータオル、及び同様物の製品の様々な他の構成要素を形成し得る。
従来技術のアプローチは、特に、強靱な又は引裂き抵抗性フィルムで、機械横断方向に幅広の寸法を有する開口部を形成するのには適していない。よって、従来技術アプローチで得られるよりもより大きな機械横断方向寸法を有する、ウェブ材料の開口部を得るために、同一のプロセス工程で(すなわち、同じニップ内で、かつ開口部形成歯がまだウェブに貫通している間に)、開口部形成とそれに次ぐ伸張とを可能にするプロセスを設計することが望ましい。従来技術アプローチは、また、本明細書に記述されるもののような高速の開口部形成及び伸張手段を使用した、溝内に配置された開口部を備えた、***と畝が交互に配置されたウェブを作製するのには適していない。
一般に、この装置は2つの噛み合い形成構造を含み、それらの間にニップを形成する。形成構造は、ウェブに質感を付与することができるローラー、プレート、ベルト、スリーブ、その他の構造、又はこれらの組み合わせを含み得る。第1の形成構造は、この形成構造の表面上に複数の第1***及び第1溝を含み、この第1***は、上面を有し、この第1溝は下面を有する。この第1形成構造は更に、第1***の上面から外方向に延出する、複数の離間した歯を含み、各歯は開口部を形成することができ、この第1***の上面は、前記歯の先端と、前記第1溝の下面との間に配置される。第2形成構造は、複数の連続的な第2***及び第2溝を含む。
図17に示すウェブ300(微小開口部312及び微小開口部314)のように、ポリマーフィルムに開口部を形成するための非限定的な一実施例において、装置は、係合深さ3.8mmで1.5mmピッチリングロールと相互に噛み合う、1.5mmピッチの凸状***RKAロールを含んで使用され得る。凸状***RKAロールは、長手方向がMD方向になるように向けて配置される歯を有する。歯は、図5Aに示すようにずれたパターンで配置される。歯は、底面から先端の尖点まで先細になった6つの面を備えた角錐形状を有し、高さhtは4.7mmである。歯は、夾角(図5Bのα)が62度、歯の長辺の側壁角度が約6度(図5Cのβ)、及び、端面夾角が90度(図5Eのγ)である。RKAロール上の歯の間にわたる***は丸み付けされておらず、平らな表面を形成する。歯は図6Bに示すように、やや切頭された形状の***に形成される。***及び溝は、リングロールの周りに円周方向に延在する。
溝内に開口部を有する波形ウェブを製造するための非限定的な一実施例において、装置は、係合深さ6.3mmで2.0mmピッチリングロールと相互に噛み合う、2.0mmピッチの凸状***RKAロールを含んで使用され得る。凸状***RKAロールは、長手方向がMD方向になるように向けて配置される歯を有し、***及び溝は、リングロールに沿って円周方向に延在する。歯は、図5Aに示すようにずれたパターンで配置される。歯は、底面から先端の尖点まで先細になった4つの面を備えた角錐形状を有し、高さhtは6.9mmである。歯は、夾角(図5Bのα)が57度、及び歯の長辺の側壁角度が約5度(図5Cのβ)である。RKAロール上の歯の間にわたる***は丸み付けされておらず、平らな表面を形成する。歯は図6Cに示すように、切頭されていない形状の***に形成される。歯は、MD方向の先端間歯間隔SMDが8.0mm、断面深さ(図6Aのdcc)が3.7mm、結果として得られる***高さ(図6AのhR)が3.2mmである。
