Sealing method and apparatus for vacuum treatment of support for light-sensitive material.

摘要

In a method in which a thin-film support (1) is continuously led into a vacuum chamber (3) 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 (9) and leading-out rollers (10) which are close to each other through slight distances (S), 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. <IMAGE>
