Abstract

La présente invention porte sur un dispositif d'alimentation en matériau de base en feuille (6) pourvu d'un dispositif de support (8) qui supporte un premier rouleau de matériau de base en feuille (R1) et un second rouleau de matériau de base en feuille (R2), et d'un dispositif de liaison (9) qui relie une partie d'un premier matériau de base en feuille (OS1) du premier rouleau de matériau de base (R1) et une extrémité (Osa) du second matériau de base en feuille (OS2) du second rouleau de matériau de base (R2). Le dispositif de liaison (9) est pourvu d'une unité de maintien d'extrémité (24) qui maintient l'extrémité (Osa) du second matériau de base en feuille (OS2), et d'un premier élément de pression (22a) qui presse la partie du premier matériau de base en feuille (OS1) contre l'extrémité (Osa) du second matériau de base en feuille (OS2).
