Abstract
A system which enables a film, e.g. a photosensitive material film, to be continuously laminated on and delaminated from a surface of a substrate, e.g. a hologram original plate, and allows duplication to be continuously effected. The system includes a film supply part (32) for supplying a film (1), a film laminating part (37) for continuously laminating the supplied film (1) on a film laminating substrate (35), a film delaminating part (37') for continuously delaminating the film from the substrate (35), and a film take-up part (43) for taking up the delaminated film. In the system, no air bubbles are trapped when the film (1) is laminated on the substrate (35), and no peel unevenness, e.g. undesired line, occurs when the film (1) is delaminated from the substrate (35). The system is suitable for use in a hologram duplicating apparatus, a dimple relief pattern duplicating apparatus, a microscopic test sample preparing apparatus, etc.
