Abstract
Abstract METHOD AND DEVICE FOR ATTACHING A THERMOPLASTIC FOIL AT A SUPPORTING STRUCTURE WHEREIN THE FOIL IS HEAT SEALED OR WELDED TO A HOLDING PLATE FORMED BY A METALLIC CORE AND A THERMOPLASTIC COVER LAYER. THE HOLDING PLATE IS REGIDLY CONNECTED TO THE SUPPORTING STRUCTURE AND SUBSEQUENTLY THE FOIL IS PLACED OVER THE HOLDING PLATE. WELDING HEAT IS GENERATED BY CREATING A HIGH FREAUENCY FIELD BETWEEN THE METALLIC CORE OF THE HOLDING PLATE AND AN ELECTRODE PLACED ON THE SIDE OF THE FOIL FACING A WAY FROM THE HOLDING PLATE. THE METALLIC CORE OF THE HOLDING PLATE FORMS A COUNTER ELECTRODE.
