VACUUM LAMINATING DEVICE FOR FILM

摘要

The present invention provides a film vacuum laminating device capable of performing lamination in a vacuum state having a vacuum degree of 0.5 kPa or less. The length of a fed substrate (14a) is measured before lamination so as to change the length of a lamination film (21) attached according to the length of the substrate (14a). A film length adjusting tool (23) for changing a maintaining and supporting length of the lamination film (21) is disposed between a half-cut position and a knife edge unit (24) installed near to a lamination roll (26) according to the measured length of the substrate (14a). The lamination film (21) before peeling a projection film (27) having a changed maintaining and supporting length of the lamination film (21) is half-cut in a length position of the attached lamination film (21) by means of the film length adjusting tool (23). The lamination film (21) is returned to the knife edge unit (24) by film returning means (20, 29) while being continued by the protection film (27).
