Abstract

L'invention concerne un procédé qui consiste à appliquer un adhésif (6) sur une découpe de carton (1) pour effectuer le collage sur toute la longueur d'un bord de coupe non métallique en dents de scie (2) de type à fusion. L'étape suivante consiste à soumettre les extrémités opposées (2c) dudit bord de coupe (2) à une soudure par ultrasons (20), ce qui permet d'obtenir aux extrémités en question (2c) où l'action de l'adhésif (6) tend à être instable, un collage efficace qui empêche l'enlèvement par pelage du bord de coupe (2) pendant son utilisation.
