  • Patent number: 4136536
    Abstract: The present invention relates to sealing devices and is most expedient to be applied in dyeing-and-finishing processes involved in textile industry. The hermetic seal of the chamber for treatment of bandlike material at an excess pressure has a hollow shell accommodating a pair of driving rollers for traversing the material under treatment, and a sealing device which hermetically divides, along with the rollers, the shell interior into an excess pressure zone communicating with the chamber, and an atmospheric pressure zone communicating with the atmosphere. According to the invention, communication between the atmospheric-pressure zone and the atmosphere is established through the agency of a check valve provided in the shell and made as a flexible sleeve whose bore is adapted for the bandlike material under treatment to freely pass. Such a constructional arrangement provides for reliable hermetic sealing of the chamber for treating bandlike material under an excess pressure.
