Abstract

L'invention concerne une machine pour carton ondulé double face destinée à joindre une feuille continue simple face ondulée à au moins une couverture supplémentaire, à l'aide d'un adhésif, qui comprend deux bandes d'amenée opposées (14, 16) transportant entre elles les matières (10-12) à joindre, la bande inférieure (16) étant supportée par une table et la bande supérieure (14) étant poussée vers le bas par pression d'air, et qui comprend un dispositif de chauffage diélectrique (30, 32, 34) agencé de façon à produire un rayonnement traversant la matière, de manière à chauffer l'adhésif et à le durcir au moins partiellement.
