そこで本発明は、樹脂シートを管の外面に圧着
するに際し、この樹脂シートと管の外面との間の
空気を確実に逃がして、気泡の発生を防止するこ

したがつて、各ダンパにて空気管からの空気を
適当に減圧し、各チヤンバの噴出口の噴出圧力を
調節して、管の樹脂シート既巻側から樹脂シート
未巻側に向けて漸次圧力が減少する空気を噴出す

樹脂シート既巻側を空気が通過することがなく、
この重ね巻き部を確実に密着させてシールさせる
ことができるものである。
以下、本発明の一実施例を図面にもとづいて説

回転しながら長手方向に移動する管であり、この
管１の近傍には、帯状の樹脂シート２を連続して
押出する押出機３が配設されている。すなわち、
押出機３からの樹脂シート２を、上記管１の運動

付けるものである。
樹脂シート２の巻き掛かり部４近傍、すなわち
樹脂シート２が管１への巻付接触を始める部分の
近傍には、樹脂シート２の幅よりもやや大きめの
噴出幅を有して、この樹脂シート２に近接した位
置からこの樹脂シート２に向けて空気を噴出する
空気噴出ノズル５が、管１と平行な方向に配置さ

側６から樹脂シート未巻側７に向けて、漸次噴出
圧力を減少させることが可能となる。
作用を説明する。第２図に示すように、管１を
周方向に回動させながら長手方向に移動させ、押
出機３から加熱状態の樹脂シート２を連続的に押
出させて、管１に巻き付ける。この巻き付けは、
第３図に示すように樹脂シート２の一部が相互に
重なるようにして、らせん状に施すようにする。
空気噴出ノズル５を動作させると、第３図に示す

つた部分側に高圧の空気が噴出され、この部分が
強く圧着される。これに対し樹脂シート未巻側７
