The invention relates to a device for sealing a cover element into a casing part of a packaging body made of composite material. The aim of the invention is to provide a device of the aforementioned type with which the sealing process should ensure in as few steps as possible, and to enable the device to be easily adapted to different cross-sectional shapes of the casing part. To these ends: an inductor ring (3) is provided; the inductor ring (3) encircles the casing part and is adapted to the course of the periphery of the casing part; the inductor ring (3) has at least two segments (4, 5, 6, 7) that form a ring; the segments (4, 5, 6, 7) can be displaced in the plane of the cover element whereby enabling the cross-sectional area enclosed by the segments (4, 5, 6, 7) to be altered; at least one first joint (10) between two segments (4, 7) is provided so that it is electrically non-conductive, and; the other joints (11) are provided so that, regardless of the relative position of the segments (4, 5, 6, 7) to one another, an electrical contact exists between adjacent segments (4, 5, 6, 7).
L'invention concerne un dispositif permettant de souder un élément de recouvrement dans la partie latérale d'un corps d'emballage constitué d'un matériau composite. L'objectif de cette invention est de créer un dispositif de soudage qui permet de mettre en oeuvre un procédé de soudage comportant le moins d'étapes possible et qui s'adapte facilement aux différentes formes de section transversale de la partie latérale. A cet effet : un anneau d'induction (3) est prévu ; cet anneau d'induction (3) entoure la partie latérale et suit le tracé du pourtour de ladite partie latérale ; l'anneau d'induction (3) comporte au moins deux segments (4, 5, 6, 7) qui forment un anneau ; ces segments (4, 5, 6, 7) peuvent être déplacés dans le plan de l'élément de recouvrement de façon à modifier les surfaces transversales entourées par lesdits segments (4, 5, 6, 7) ; au moins un premier joint (10) est formé de manière électroisolante entre deux segments (4, 7) ; et les autres joints (11) sont formés de façon qu'il existe un contact électrique entre des segments adjacents (4, 5, 6, 7), indépendamment de la position relative des segments (4, 5, 6, 7) les uns par rapport aux autres.
