Description

【発明の詳細な説明】 （産業上の利用分野） この発明は、特許請求の範囲第１項前提部分に記載の方
法、および第８項前提部分に記載の装置に関する。
（従来の技術・発明が解決しようとする問題点）この種
の装置が米国特許明細書第５５８８０１７号によシ周知
である。しかしこの装置で製造されたチューブ体は溶接
継ぎ目の外側合わせ部に未溶接箇所があシ、この部分が
剥離し裂は易くされあることが判明した。内部に剥離し
た材料片が被包装物に混入してこれを許容できない程に
汚してしまうことがある。
本発明は、剥離し易い箇所を、溶接中に溶接継ぎ目から
押し出された材料で形成するとの考えから生まれた。押
し出された材料の外側合わせ部はごく薄いので早く冷え
、それゆえ隣接した材料と溶接されることがない。
そこで本発明は、溶接継ぎ目に、押し出された材料から
なる未溶接合わせ部など生じない冒頭述べた種類の方法
および装置を提供することを目的とする。
（問題点を解決するための手段） この課題は、本発明によれば、特許請求の範囲第１項お
よび第８項の特徴部分に明示した特徴により解決される
。
（作用・効果） 被溶接継ぎ目に隣接した内テープに設けである長手溝が
溶接継ぎ目に特定の形状を付与する一方、材料の張出し
縁を防止する。溶接継ぎ目がち密に保たれることＫより
帯状フィルムの重ね合わせた合わせ部は均一に加熱され
、早く冷やされる材料箇所など生じない。長手溝が内テ
ープに設けであることにより溶接継ぎ目が内方に移動し
、製造されたチューブ体は外面が実質的に平らになる。
本発明による解決法の利点として更に、内層のみが完成
した包装チー−ブの中身と接触する積層帯状フィルムの
場合に、帯状フィルムの内側合わせ部の縁が横断面を斜
めに切断され、内層が帯状フィルムの残りの層から張り
出しても内層は溶接継ぎ目で連続して接合される。内テ
ープの長手溝により、張ｐ出した合わせ部範囲は残りの
層を覆って反対側の合わせ部範囲の内ｊ＊に１で押し下
げられる。
本発明による解決法の成果は高級包装チューブの申し分
のない溶接継ぎ目にある。
特許請求の範囲第２〜４項および第９〜１０項に記載の
好ましい実施態様は、積層帯状フィルムの１層を金属層
、好ましくはアルミニウム層とし、それを誘導加熱して
隣接合成樹脂層を溶接温度にすると有利である。
特許請求の範囲第５〜７項および第１０．１層項に記載
の好ましい実施態様は、帯状フィルムを加工する際金属
層が含まれていない点で有利であり、または高周波エネ
