Beschreibung
Zusammenfassung:	A sealing device which includes a floating horn; a support for the floating horn; and an anvil. The floating horn has a curved face with a smooth continuous surface. The curved face of the floating horn is configured to engage proximate a first end of the anvil as the floating horn is positioned in a first slanted direction relative to said anvil. The floating horn engages the anvil along its length to proximate a second end of the anvil as the floating horn is rotated to a second slanted direction opposite to the first slanted direction. L'invention porte sur un procédé et sur un appareil pour sceller hermétiquement des films. Dans un mode de réalisation, le dispositif de scellement hermétique comprend une trompe et une enclume. Le film a une partie standard et une partie augmentée. Une énergie accrue est appliquée au film dans la partie augmentée par rapport à l'énergie appliquée à la partie standard. Ce procédé permet le scellement hermétique d'un nombre variable de couches.
