Abstract
In a method in which a thin-film support is continuously led into a vacuum chamber from the atmospheric air, subjected to surface treatment and led-out to the atmospheric air again, a pneumatical cutoff portion of a leading-in and leading-out section is constituted by seal roller sets each of which is formed by aligned pairs of leading-in rollers and leading-out rollers which are close to each other through slight distances, and the support is led-in and led-out while lapped at an angle of from 30 to 150 degrees around the pair of rollers nearest to the atmospheric air of the seal roller sets.

A sealing apparatus for vacuum treatment of a support for light-sensitive material, in which a thin-film support is continuously led into a vacuum chamber from the atmospheric air, subjected to surface treatment and led-out to the atmospheric air again, comprising:
- a leading-in and leading-out section having a leading-in portion and a leading-out portion;
- at least one seal roller set formed by
- a leading-in roller, located in the leading-in portion of the leading-in and leading-out section, and
- a leading out roller located in the leading-out portion of the leading-in and leading-out section, wherein said leading out roller is adjacent said leading-in roller, and
- auxiliary rollers being positioned to set a lap angle of the support around said leading-in roller and said leading out roller of said at least one seal roller set in a range of from 30 to 150 degrees.
