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 vof the coating roll and the circumference velocity vof the takeup guide roll. Hence, v=v. 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.
