この素材を用いてチユーブを製造するには大別

第８図に示すように、ラミネートフイルム１を
円筒状に曲げ両端を重ね合わせ、重ね合わせ部を

では、筒体２を一つ一つ金型に挿入しなければな
らないので、人手を要し安全性に問題があり、高
価なインジエクシヨンマシンの稼動率が下がる。
後者の方法では、フイルムの筒状化と、口部の成
形が別工程で行なわれるため、それぞれの工程を
最も能率的な条件下で生産できる。しかしこの方
法で問題となるのは、別々に成形した口部３と筒
体２との溶着工程である。これにはヒートシール
による方法と、高周波誘導加熱による方法とがあ
る。ヒートシールによる方法では、シールに時間
がかかること、溶着用金型の温度管理が難かしい
ことなどから高速で安定した生産には不向きであ
る。そのため、最近では高周波誘導加熱による方
法が注目されている。
高周波誘導加熱による方法の原理は、第１１図
に示すように、筒状導体４の周囲にワークコイル

１２図に示すように、筒状導体４には、ワークコ

じ、その向きはワークコイルの電流の向き６とは
逆向きである。この電流は一種の短絡電流となり
ジユール熱を発生する。しかし筒状導体４が第１
３図に示すように、周方向の一部において不連続
であると、筒状導体４に流れる電流７は、第１３
図に示すようになる。筒状導体４に一端に沿つて
溶着を行なうためには、筒状導体４の一端に接近

連続部分で電流密度が大きくなり温度は高くなる
が、コーナー部８では殆んど電流が流れず温度が
上昇しない。第９図に示した筒体２の一端に別途
成形した口部３を高周波加熱によつて溶着する場
合も、加熱状況は第１３図の場合と同様となり、
満足な溶着加工を行なうことは出来ない。
この問題を解決するために、第１４図に示すよ
うに、口部３の中に円板状アルミシート９を埋め
込み、アルミシート９の外周にワークコイル５を
配置して高周波電流を流し加熱することによつ

と筒体２を溶着することが行なわれている。しか
しこの方法では、アルミシート９を口部３に埋め
込むために、口部３の成形に当つて金型内にアル
ミシート９を一つ一つ配置しなければならないの
で、生産性、安全性に問題が残る。
〔発明が解決しようとする問題点〕
本発明はラミネートフイルムからなる前記の筒
体２の端部に、プラスチツク成形品である前記の
口部３のような部分品を溶着するに当り、口部３

装置を提供せんとするものである。
〔問題点を解決するための手段〕
本発明はこの目的を達するために、絶縁物から

〔作用〕
第３図に示すように、ワークコイル５の近くに
ワークコイル５に沿い平行に金属リング１０を配
置し、ワークコイル５に高周波電流を通ずると、
電磁誘導作用により金属リング１０に電流を生
じ、その電流の向きはワークコイル５に流れる電
流の向きとは逆となる。このときワークコイル５
及び金属リング１０に生ずる磁力線の向きは第４
図に示すように互に逆向きとなり、ワークコイル
５によつて発生する磁力線を、金属リング１０に
よつて発生した磁力線が打消すように作用する。
しかしワークコイル５と、金属リング１０とは接
近して配置されているので、両者の対向面の間で
は、磁力線は同一方向になるため強め合うことに
なり、結果的に金属リング１０がない時のワーク
コイル５による磁力線の広がりを、金属リング１
０を配置することによつてワークコイル５と金属
リング１０の間に集束させることができる。第５
図に示すように集束された部分での磁力線１１の

て集束された磁力線１１は、ワークコイル５と金
属リング１０の内部に置かれた被加工物である筒
体２の側面を放射状に貫く。これにより発生する
電流１２は、筒体２を周方向に流れるのではな

の合成電流１３の基本単位は、第５図に示したよ
うに、磁力線１１を軸とした微小面であるため、
合成電流１３の帯のどの部分でも均一な電流密度
が得られ、第１３図に示したような流れ方はしな

即ち金属リング１０を配置することにより、合

端部を周方向において均一に加熱することがで
き、別に成形した口部３との溶着を極めて安定に
