Abstract

L'invention concerne un appareil de liaison de surface incurvée (10) et un procédé de liaison de surface incurvée, destinés à être utilisés dans la liaison d'un substrat (20) et d'un matériau de film souple (30). Le substrat (20) comprend une surface de liaison (22) destinée à être liée au matériau de film souple (30), et la surface de liaison (22) comprend une partie de surface incurvée (222). Un appareil de liaison (146) comprend un premier rouleau (1461) destiné à enrouler le matériau de film souple (30) sur le substrat (20) en vue de lier le matériau de film souple (30) sur le substrat (20), et comprend en outre un second rouleau (1463) destiné à enrouler le matériau de film souple (30) sur le substrat (20) lorsque le premier rouleau (1461) roule vers une position correspondant à la partie de surface incurvée (222). Ainsi, une force latérale peut empêcher le substrat (20) de tomber d'une plateforme de substrat (12), lorsque le premier rouleau (1461) roule vers la position correspondant à la partie de surface incurvée (222), ce qui améliore la qualité de liaison.
