ABSTRACT:
A sealing arrangement for use at the inlet and outlet of containers in which a pressure above or below atmospheric pressure prevails, especially for treating webs of textile material. The sealing arrangement comprises two endless belts respectively looped around two pairs of reversing rollers with the rollers of each pair spaced from each other so that straight belt sections are formed between the rollers of each pair of reversing rollers. The web of goods is passed between two adjacent straight belt sections, which respectively pertain to the two endless belts, and rim portions, and which seal the space surrounded by the belts and located between the rollers against the pressure surrounding the container. The two reversing rollers of each belt which are respectively remote from the inlet and outlet of the container and/or the reversing rollers respectively adjacent the outlet of the container are adjustable relative toward and away from each other while the lateral rim portions of the belts sealingly engage the lateral container walls or walls parallel thereto.
