The invention is directed to improving a sealability on end surfaces of elastic rolls and reducing a rotating load. A sealing device (20) is provided for gastightly sealing outlet/inlet of a bright annealing furnace (22) with respect to a metallic web (21). The metallic web (21) is held on both side thereof between a pair of elastic rolls (23) so that it can pass therebetween while being gastightly sealed thereby. Provided between end surfaces of the elastic rolls (23) and a side wall (26) of a casing (25) are skin members (34) and end surface sealing members (39), which are formed of an elastic material, for positive sealing. Provided between the skin members (34) and the end surface sealing members (39) are first support members (35), second support members (36), outer bearings (37) and inner bearings (38), all of which made from a rigid material, to attain reduction of a rolling load. <IMAGE> |
