  • Vacuum vapor-deposition apparatus and method of producing vapor-deposited film
    Patent number: 7754015
    Abstract: This invention relates to a vacuum vapor-deposition apparatus for forming vapor-deposited films on a base film, thereby to produce vapor-deposited films, and also to a method of producing vapor-deposited films. In the vacuum vapor-deposition apparatus, the synchronizing means equalizes the circumference velocity v1 of the coating roll and the circumference velocity v2 of the takeup guide roll. Hence, v1=v2. Therefore, the takeup guide roll never rubs the vapor-deposited layer provided on the surface of the film. This eliminates the possibility that the vapor-deposited layer has scratches. The vapor-deposited layer can therefore possess desired properties.
