ABSTRACT:
For sealing a high pressure steamer air, pressurized to a level higher than the internal pressurized medium, in the drum body of the high pressure steamer is directed against the mutually contacting portions of rubber seal rolls. Initially, the pressurized air flows over the outside of a cylindrical duct extending between the opening for the passage of textile articles into the drum body of the steamer and the rubber seal rolls and the air serves to block the flow of the pressurized medium within the steamer through the opening. Sealing plates positioned between the interior of the steamer and the seal rolls, are forced into contact with the seal rolls by the pressurized air. Further the flow of pressurized air collides with the internal pressure medium of the steamer within the cylindrical duct preventing the exhaust of the internal pressure medium through the cylindrical duct.
