Abstract

La présente invention concerne un appareil de production de noyau stratifié de type adhésif et son unité d'application d'adhésif qui comprennent : une unité d'application d'adhésif destinée à appliquer de manière sélective, sur les surfaces des matériaux transférés en continu, un adhésif uniquement à un moment d'application souhaité ; et une unité de découpage destinée à découper les matériaux qui sont passés à travers l'unité d'application d'adhésif et à former ensuite de façon séquentielle des éléments laminaires selon une forme prédéterminée. L'unité d'application d'adhésif et l'unité de découpage sont configurées de sorte à fonctionner de telle manière que le moment où l'unité d'application d'adhésif applique l'adhésif soit synchronisé avec le moment où l'unité de découpage découpe les matériaux.
