Title
(DE) Werkzeug zum Verschweissen eines Einsatzteiles zwischen zwei Kunststofffolien und Verfahren zum Verschweissen dieser Teile
Abstract
(DE)

Das Werkzeug zum Verschweißen eines Einsatzteiles (27) zwischen zwei Kunststofffolien (25, 26) mittels HF-beaufschlagten Elektroden (20, 21, 22, 23), die der Kontur des Einsatzteiles (27) angepasst sind, weist eine Anordnung auf, bei der bezogen auf die durch die Berührungsfläche der Folien gebildete Trennebene (3, 4) sowohl das Hauptfeld (31) als auch das Streufeld (29) symmetrisch ausgebildet sind.
