Zusammenfassung:	PURPOSE:To enable inhibition of vibration and dimensional correction while supporting a strip in non-contact manner, by spraying a molten metal in a coating bath to the surfaces of a rising strip from nozzles located inside the coating bath through pumps. CONSTITUTION:Nozzles 10, 10a are located to spray a molten metal to the two surfaces of a strip 1 running from a coating roll 6 and a top roll 7 in a coating bath 5. Their nozzle openings are directed to the surfaces of the strip 1, and the nozzles 10, 10a are connected to the outlet side of molten metal pumps 12 through pipes 11. The molten metal in the coating bath 5 is sucked through the pipe 11a at the suction side by operation of the pump 12, and spouted from the nozzles 10, 10a to the surfaces of the strip 1. The strip 1 is supported with the resultant spout pressure. Consequently, the supporting power is strong, and the strip 1 is supported in non-contact manner. Thus, maintenance and management of the device are facilitated.
