Abstract
Description
複合ガラス積層体を製造する際に使用されるプラスチックシート(中間層シート)は、通常、意図的に施与された粗さを有する。なぜならば、そのようにして、積層プロセスにおいてガラス板と中間層シートとの間に閉じ込められた空気を除去することができるためである。
従来技術において公知の多数のエンボス加工法の場合、プラスチックシートは片面又は両面に2つのローラの間に規則的又は不規則的なエンボスパターンを有している。例えば、EP1233007A1には、溝により形成された規則的な表面構造を有する中間層シートの製造が開示されている。溝はリブにより相互に分かれており、その際、リブは溝について広範囲な開口を有していてよい。更に、溝中には、積層体の迅速な脱気を妨げるバリアが存在していてよい。他方で、閉じ込められた空気はあまりに迅速に、ひいては制御されずに漏出してはならず、それというのも、さもなくば、積層体の早期の部分封止が生じ得るためである。
従って、本発明の課題は、複合ガラス積層体の製造の際に良好な脱気挙動を示す表面構造を有するプラスチックシートを提供することであった。
従って、本発明の対象は、少なくとも1つの面上に、突起(a)の平行に配置された列からなる表面構造を有するプラスチックシートであって、前記の突起(a)が、突起(a)よりも少なくとも10%低い高さを有するウェブ(b)により相互に連結されているプラスチックシートにおいて、ある列の突起が隣接する列のウェブに接しかつ共通の谷底(c)を形成するように、平行に配置された列が相互にずらして配置されていることを特徴とするプラスチックシートである。最も単純な場合には、2つの隣接する列の突起及びウェブは交互にシート上に施与されている。
