摘要：
A sealing means for a container which permits the entrance or exit of a web of material to be treated inside the container. Three cylindrical rolls are rotatably mounted in series in the opening of the container and three endless sealing strips of resilient material are pressed against the three rollers. The sealing strips each have two straight portions, each arranged parallel to the axis of the roll. Each sealing strip also has two circular portions near each end of its roll which join the ends of the straight portions. The web material is passed between the sealing strips and the surface of each of the rolls.
