Abstract

La présente invention concerne un dispositif permettant de fabriquer un noyau stratifié de type adhésif qui comprend : une unité d'application d'adhésif qui applique un adhésif sur la surface d'un matériau transféré en continu et seulement à un moment d'application souhaité ; et une unité de découpage qui découpe le matériau qui est passé à travers l'unité d'application d'adhésif, ce qui permet de produire de façon séquentielle des éléments laminaires ayant une forme prédéterminée, le moment d'application de l'adhésif de l'unité d'application d'adhésif et le moment de découpe du matériau de l'unité de découpage étant synchronisé lors du fonctionnement.
