  • Publication number: 20120178037
    Abstract: A roller sealing device arranged at an access port of a continuous furnace for adapting a continuous processed planar processed material. The rolling device includes a pair of first roller carriers arranged correspondingly opposite to each other, each having a first roller assembly. Each first roller carrier includes a first sealing roller and two first auxiliary rollers; the first sealing roller and two first auxiliary rollers are pivoted to a respective one of the first roller carriers; the two first auxiliary rollers are located between the first sealing roller and the corresponding first roller carrier. The first auxiliary rollers rollingly abut against the first sealing roller and the corresponding first roller carrier. Therefore, the roller sealing device is sealed well so as to prevent the gas from leakage. The present invention further provides a gas-sealing method.
