Abrégé
(EN) An apparatus in the production of a package or a packaging material comprising at least one metal layer and one polymer layer, the apparatus including an inductor connectable to a high frequency current source. According to the invention, said inductor includes a core (1) of a ferromagnetically conductive material, the core displaying two shanks (5a, 5b) with an air gap (6) between a first respective end of these shanks (5a, 5b), as well as an arc section (7) which interconnects a second respective end of the two shanks (5a, 5b) with each other for conducting a magnetic flow (8) between the shanks, the arc section (7) displaying an electrically conductive coil (2) wound around same, the coil displaying connection points (3a, 3b, 11a, 11b, 11c) for said high frequency current source (4).
(FR) L'invention concerne un appareil permettant de produire un emballage ou un matériau d'emballage comprenant au moins une couche métallique et une couche polymère, ledit appareil renfermant un inducteur pouvant être connecté à une source de courant haute fréquence. Selon l'invention, ledit inducteur comprend un noyau (1) de matériau conducteur ferromagnétique, ce noyau possédant deux tiges (5a, 5b) séparées par un espace d'air (6) situé entre les premières extrémités respectives de ces tiges (5a, 5b) ainsi qu'une section en U (7) qui relie les secondes extrémités respectives des deux tiges (5a, 5b) aux autres afin de conduire un flux magnétique (8) entre lesdites deux tiges, la section en U (7) étant dotée d'une bobine électroconductrice enroulée autour de celle-ci, et ladite bobine présentant des points de connexion (3a, 3b, 11a, 11b, 11c) avec la source de courant (4) haute fréquence.
