Description
- Zusatzeinrichtung zur 8Kontinuierlichen Schweißvorrichtung für thermoplastische und teil thermoplastische Folien (Zusatzanmeldung zur Patentanmeldung Aktenzeichen P 24 23 321.4) Die Erfindung bezieht sich auf eine Erweiterung der Vorrichtung zum fortlaufenden Herstellen von Schweißnähten an Folienbahnen aus thermoplastischem Material, wobei diese mittels einem erwärmten , in einem Rollensystem geführten Draht an der gewünschten Stelle zum Schweißen bzw. Schweißtrennen gebracht werden.
- Der Erfindungsgedankte liegt darin, daß die Erwärmung des Drahtes nicht nur durch Widerstandserwärmung, sondern auch berührungsfrei unmittelbar vor dem Anpressen auf die Folien, erfolgen kann. Dies wurde durch Hinzufügung einer zusätzlichen Induktionsspule 28 zwischen Kontaktdraht 1 und Antriebsrad 2 gelöst (Abb. la).
- Der Vorteil dieser Erfindung liegt darin, daß die zum Schweißen erforderliche Wärmeenergie kontaktlos, vor dem Aufsetzen des Drahtes auf den Kunststoff, dem Draht so zugeführt wird bzw. in diesem gespeichert wird, daß eine Schweißung zwischen den Punkten 32 und 33 sowie eine Nachwirkzeit zwischen den Punkten 33 und 34, entsteht.
- Die Zusatzeinrichtung bringt auch den Vorteil, daß der nun induktiv erwärmte Schweißdraht in einem absolut potentionalfreien Rollensystem geführt werden kann.
