ABSTRACT:
An improved vacuum treatment system includes containers for accommodating articles to be treated, a tunnel-like casing in which a plurality of the casings can move contiguously, a driving device for making the containers move in the casing, a plurality of evacuation ducts open to the casing at a plurality of locations, sealing devices for sealing the clearance between the outer surfaces of the containers and the inner surface of the casing at the positions between the openings, and an evacuation facility for evacuating the inside of the casings through the evacuation ducts. The locations of the evacuation ducts closest to the opposite ends of the casing are spaced apart from the ends of the casing by distances greater than the length of the container. The intervals between the locations of the evacuation ducts are preferably longer than the length of the container. There can also be provided a plurality of tunnel-like casings, the insides of which are evacuated by a single evacuation facility through the evacuation ducts.
