Abstract
Description
用語「吸収性物品」は、生理用ナプキン、パンティライナー、タンポン、陰唇間装置、創傷包帯、おむつ、成人失禁用物品、拭き取り用品等の使い捨て物品を含む。更に、本明細書に開示される方法及び装置によって生産される吸収性部材は、研磨パッド、ドライモップパッド(SWIFFER(登録商標)パッド等)等の他のウェブにおいても有用であり得る。かかる吸収性物品の少なくとも一部は、月経又は血液、膣分泌物、尿、及び便等の体液の吸収を目的とする。拭き取り用品は、体液を吸収するために使用されてもよく、又は表面を洗浄する等、他の目的で使用されてもよい。上記の種々の吸収性物品は、典型的には、液体透過性トップシート、トップシートに接合される液体不透過性バックシート、及びトップシートとバックシートとの間の吸収性コアを含む。
本発明は、変形ウェブ材料、並びにウェブを変形させるための方法及び装置に関する。更なる特性を有するウェブを提供する、ウェブ中の新しい構造を形成することが可能である、方法及び装置が開示される。用語「変形ウェブ材料」が本明細書で利用されるが、目的は、かかる変形ウェブ材料から吸収性物品のための吸収性部材(又は非吸収性構成要素)等の構成要素を作成することであることが理解されるべきである。そのような場合、変形ウェブ材料は、吸収性物品のための個々の構成要素に切り分けられる。変形ウェブ材料はまた、梱包材料及びごみ袋が挙げられるがこれらに限定されない、吸収性物品以外の製品で使用され得る。
従来技術のアプローチは、特徴の制御された配置を伴う、明確に画定された、混合された特徴を作成するのに好適ではない。したがって、特徴の2つ以上のセットの形成に対するより良好な独立制御を可能にするプロセスを設計することが望ましい。特徴の各セットの形成に対するより良好な独立制御を達成するための2つのアプローチが、ここに提供される。1つのアプローチは、別個の雄型形成要素を備える2つのロールを有する、単一ニップを利用し、少なくとも1つのロールは、2つ以上の凸状隆起部を備える。第2のアプローチは、特徴の複数のセットの制御された配置及び配向を可能にするマルチヒット(マルチニップ)構成を含む。これらのアプローチのそれぞれは、特徴の所望の寸法及び/又は形状が達成されるように、特徴の各セットの形成に対する独立制御、及びウェブのロールとのより良好なパターンの適合を可能にし得る。
以下の図面は、特定のロール配列の非限定的な実施例、及びそれによって形成され得る変形ウェブ材料を示す。
図14は、それらの間に単一ニップNを形成する単一対のロールを備える装置160の一実施例を示す。ロールは、ウェブの表面に対して異なる方向で配向される、少なくとも2つの変形のセットで、ウェブを変形させるために構成される。これは、ロールの外周の周囲に延在する複数の隆起部164及び溝166、並びに隆起部164の上面から外側に延在する複数の第1の離間した形成要素168を有する、ロール162の1つを提供し、その表面上に複数の第2の形成要素172を有し、第2の形成要素の先端が、第1のロール162上の隆起部164の少なくとも一部の頂部を越える深さまで、第1のロールの軸に向かって内側に延在する、第2のロール170を提供することによって達成され得る。
本明細書の所望の方法はまた、複数の変形工程を利用してもよい。かかる複数の変形工程は、本明細書の上記の節に記載される任意の好適な装置によって実施され得る。複数の変形工程を利用する方法が、標準入れ子配列で比較的少数のロールを有する入れ子装置で実施されるものとして示されるが、これは、図を簡単にするために行われ、本明細書に記載される装置(混成、閉ループ、及び共通バンク装置等)のいずれも、所望の変形を実施するために、任意の好適な数のロールと共に使用され得ることが理解されるべきである。
変形ウェブ材料及びそれを作成する方法の多くの代替の実施形態が可能である。
