PCT No. PCT/JP94/02100 Sec. 371 Date Jul. 14, 1995 Sec. 102(e) Date Jul. 14, 1995 PCT Filed Dec. 14, 1994 PCT Pub. No. WO95/16888 PCT Pub. Date Jun. 22, 1995A danger of explosions or fires caused by a spark of static electricity in sealing portions of compartment gateways of continuous annealing furnaces to perform bright annealing or oxidation-free annealing of metal strips, continuous painting equipments, and the like wherein a flammable atmospheric gas having a danger of explosions or fires is used, is prevented, and the formation of abrasions or scratches on the strip surface is prevented. In the sealing portions of the gateways, an elastic pad (17) including an electroconductive non-woven fabric having carbon-containing fibers, fibers having chemically formed polypyrrole as electron-conjugated electroconductive polymer, fibers made by treating acrylic fibers with a divalent copper compound and a sulfur-containing compound alone, or fibers having these fibers as the major component, provided on a surface of a sealing hardware (16), a surface of which has an electrical resistivity value of from 10-3 to 106 OMEGA xcm, and an elastic rotary roll (18) pressed respectively against a metal strip (1) and said elastic pad (17) are provided in combination.
