〔実施例〕
以下、特に本発明による方法を実施するために適した装
置の実施例を、図面に基づいて更に説明する。
加熱される貼合わせロール１と２の間には、貼合わせ隙
間３が形成される。この貼合わせ隙間には、発泡された
ポリスチロールウェッブ４が走入する。
ウェッブ４は隙間３内において、その両側に緻密質の（
発泡していない）ポリスチロールウェッブ５．６が貼合
わせられる。そのために、予め押出されたポリスチロー
ルウェッブ６が、上側の案内ロール７を介して貼合わせ
ロール１へ案内される。ウェッブ６は個所８で貼合わせ
ロール１に当たり、貼合わせロールに約４０゜巻き付け
られる。従って、このロール上でのウェッブの所定の滞
留時間が生じる。この滞留時間は貼合わせロールの周速
に依存する。
例えば、ロール１におけるシート６の滞留時間を延長す
べきときには、案内ロール７が両方向矢印９の方向に上
方へ、点線で示した位置１０まで調節される。
そのとき、シート６は非常に早く個所１１で貼合わせロ
ール１に当たり、そしてこのロールの周速が同じである
場合には９．加熱された貼合わせロール上にほぼ２倍の
時間留まる。
貼り合わせロールは約１４５°Ｃの温度であり一方、約
０．１　ｖａｎの厚さの緻密質のシート６は隙間内で最
高約１３５°Ｃの温度に達する。
発泡したウェッブ４が加熱装置１２によって４０”に加

な連結が達成される。このウェッブに貼合わせられる緻
密質のシート５゜６は、個所１１またはｌｌａで当たる
までに、約２０°Ｃの温度を有する。
シート５．６の温度は貼合わせロール１．２の周りに約
９０°巻き付けることによって、約１００°Ｃに高めら
れる。従って、隙間３内での貼合わせロール行程は約１
３０°Ｃで行われる。
緻密質のシート５．６と発泡されたウェッブ４の間の連

解除不可能であることが判明した。
案内ロール７を加熱することにより、貼合わせロールに
