【発明の詳細な説明】 本発明は、膜沢過、特に制限された浸透のために内側に
膜を取り付けた多孔性不織材料の薄壁管に関するもので
ある。
制限された浸透のために内側に膜を有する紙またはポリ
エステル繊維の不織材料のこのような管はそれ自体知ら
れている。
膜を有する繊維管は適当な予備処理をした後支持管内に
置かれる。
これらの支持管はたとえば開口を有する合成材料で作ら
れている。
その後、浄化すべき液は高圧下で膜を有する繊維管の内
側を通して導入される。
この高圧のために、液は膜を通過し不織層に到達しそこ
から支持管の開口を通して放出される。
しかし、浄化すべき液中の溶解物は、高圧の影響を受け
ても膜を通過することはできない。
それ故に、これらの溶解物はもつと濃縮した不純溶液と
してその液と共に去る。
膜を有するこのような繊維管の欠点は、その膜がすり減
ったときに支持管から全体を除去することが一般に殆ん
どむずかしいことである。
高い内圧のために、管の不織材料が支持管の内側に押し
付けられる。
上の結果、実際には、不織材料を除去するための積極的
手段をやむなく使用せざるを得ぬことになり、その結実
装置はその大規模な投資費用のために当然と認められる
よりも一般に長い開作動しないことになる。
繊維管を支持管から機械的手段によって除去するのを早
めようとしたが、その作業はいかなる良い結果にもなら
なかった。
本発明は、内側に膜沢適用の膜を取り付けた多孔性手織
材料の長さ方向の薄壁管の製造を目的とし、この多孔性
手織材料はその膜がすり減った後支持管から容易に除去
することができる。
これは、繊維管に引裂き部材を設けそれによって繊維管
が支持管から容易に除去でき少なくとも繊維管の一部が
長さ方向に引裂かれるようにして達成される。
この引裂き部材は、繊維管の上側に取り付けられた引張
り素子と、繊維管の下側に取り付けられたかぎ要素子と
から有効に成っている。
このような引裂き部材を使用した場合、膜がすり減った
後、かぎ要素子は引張り素子を引張ることによって上方
に動かされ繊維管を引裂くことができる。
非常に有効な実施例は、この引裂き部材を繊維管の不織
材料の２つの連続した層の間に取り付けることであり、
このような取り付けによりこの引裂き部材が多少この不
織材料中に埋込まれるのでこの引裂き部材の部分が膜の
いずれをも妨げることはないという利点が与えられる。
さらに、繊維管の外側部分のみがこのようにしてすり減
るから、管が完全にすり減る場合より除去はもつと有効
である。
引裂き部材は、繊維管の溶接繊維の条片時に超音波溶接
作業によって作られる長さ方向の継目から有利に構成さ
れている。
このようにして溶接すべき層は均一に加熱されるから（
通常の溶接作業においては殆んど不可能であるが）、超
音波溶接によって得られる継目は非常に信頼性がある。
さらに、超音波溶接は極めて小さい継目を与えるから実
際に維持される管を多孔性とするが、管の内部に取り付
けられた膜沢適用膜は、内圧がむしろ高い場合でも、い
かなる引裂きによっても損傷を受けることは殆んどない
。
超音波溶接工程においては側部どうしは互いに重なり合
うことができ、所望の長さ方向溶接継目は隣接する側部
どうじを突合せ溶接することにより得られる。
この工程のもう１つの利点は、非円形の断面たとえば三
角形の断面を有する管を形作るために心棒を簡単に利用
することができる。
このような断面を有する管は、たとえば繊維管のある実
施例にうまく利用される。
本発明のもう１つの目的は、上述した欠点にもかかわら
ず、そのような管を非常に簡単に製造する方法を提供す
ることを狙いとする。
それ故に、単位時間当り非常に多量の繊維管を製造する
ことができる。
これは、不織帯の側部どうじを互いの方へ連続的に折り
たたみそれらを超音波で溶接しながら繊維管に長さ方向
の溶接継目を形成することによって達成される。
本発明は、また、この方法を実施する装置にも関するも
のであり、この装置は、不織帯を供給する部材と、心棒
と、不織帯の側部領域の少なくとも一部を側部領域の他
の部分と接触させる運搬部材と、任意の隣接領域部分す
なわち連続領域部分を溶接する溶接部材とを備えている
。
この装置には、心棒の中または上に超音波溶接用の部材
が設けられまた運搬部材が設けられ、これは心棒上で不
織帯から管を形作ることができる。

ポリエステル繊維の不織繊維管１を示す。
この組立体は、膜２を通過した透過物を放出するための
開口４を有する熱可塑性材料の支持管３の中に納められ
ている。
膜がすり減ると、繊維管１の不織材料は制限された浸透
によって作られる内圧のために支持管３の面に押し付け
られる。
従って、繊維管１は支持管３から除去するのが非常に困
難となる。
この欠点をなくすために、繊維管１内に引裂き部材５を
入れるが、この引裂き部材は繊維管を引裂くためのかぎ
要素子６から成り、かぎ要素子は細線７を通して引張り
環８と接続されており、この引張り環８にはたとえば引
