Abstract:
1. A method for intermittently applying thin-film coatings, comprising: looping a band-shaped substrate ( moving the actuation roller with a predetermined timing to be retreated from the backside of the substrate to thereby separate the substrate from the application roller; in synchronization with this, moving a tension roller ( after that, moving the actuation roller with a predetermined timing to be advanced towards the frontside of the substrate to bring the substrate into contact with the application roller; in synchronization with this, moving the tension roller to be retreated from the backside of the substrate to reduce the tension exerted on the substrate and to form the thin film is formed on the surface of the substrate on an intermittent basis; and providing control such that, for the tension applied to the substrate to be kept constant all the time, the tension roller is moved to be retreated from the backside of the substrate and to be advanced towards the frontside thereof so as to follow the actuation roller being moved to be retreated from the backside of the substrate.
