発明の用途 本発明による方法及び装置は、非常に多種多様な目的に
好適である成形体の溶接束の製造に有用である。優れて
いる用途は、熱交換器又は蓄熱器の製造である。蓄熱器

る。溶接した束を、異なる温度の２つの流動媒体の間の
熱交換に使用する場合、少なくとも２つの相互に分離し
ている通路系が必要であり、一方は端面から流通しかつ
他方は束の側方から流通し得る。
代表的な蓄熱器−又は熱交換用成形体は断面積0.1〜6m2
及び長さ0.5〜10mを有する。しかし本発明は更に大きな
又は小さな束の製造も可能にする。
実施例 本発明は、一定の形状のプラスチック成形体の溶接に限

異なる形状の成形体を、それらの縁が少なくとも部分的
に面状に相互に接しかつ共通の縁（本明細書では“端

を可能にする限り、成形体の形状は任意である。薄壁の
成形体を相互に溶着すると優れている。
１つの操作工程で本発明により溶接すべき端面は１つの
面中に存在すべきであり、その面が平面であると有利だ
が、そうである必要はない。面は湾曲状、丸天井形又は
屈曲していてもよい。束は１個又は数個の端面で溶接し

体が同じ長さを有すると有利であり、２つの等しい端面

時に−本発明により溶接すると有利である。
成形体をその端面の全周で相互に溶接することはいつも
必要とは限らず、時々、それぞれが強度に対する要件を
満足する溶接個所が得られる場合にそれで十分である。
本方法の実施可能性にとつて、端部が溶接されていない
個所で面状に相互に接しているか又は自由な区間を有し
ているかどうかは問題ではない。しかしながら、端部の
面状に相互に接してはいない部分を、溶接端面が無段階
の面中に存在するように相応する溝中で溶融させること
も有利なはずである。それ故、板材のすべての溝の底面
も１つの面中に存在すべきである。
中空異形成形体の溶接では、端面では中空室だけが開放
されていてかつ個々の中空異形成形体の相互間の間隙が
端面側から貫通していないことが望ましい。この場合に

基本的にはこのような束には、異形断面が継ぎ合せられ
て閉じているすべての中空異形成形体が適している。
本発明の目的には、中空異形成形体の端部だけが面状に
相互に接しているだけで十分である。端面から離れた他
の区域では他の形状の断面を有していてよい。例えば、
主に円形の断面を有しかつ正六角形断面に拡がつている
端部を有する管を使うことができる。端部が面状に相互

若干楔形の断面の溝により簡単である。
第２図に図示した管束は六角形に拡がつている端部21を
有する円形管20 ３個より集成されている。端部は区域
22で面状に相互に接している。壁厚23はこの区域では例

周縁溝27は、外壁が溶接すべき区域と同じ平面28上に位
置するように溶融するためだけに使われる。
基本的に、本方法を実施するには１つの板材１で十分で
ある。しかし管束の両端面を２つの板材１で同時に溶接
すると優れている。これらの板材を相互に平行に、端部
が溝中に押し込まれる距離だけ相互に接近移動させる。
そのために、材料の少なくとも一方を移動させかつ溶接
