PROBLEM TO BE SOLVED: To shorten a time for escaping a liquid that is used with a liquid coating device.SOLUTION: An arrangement is made with vertical difference so that a water head difference is generated between a liquid level of a temporary reservoir 506 and a liquid level of a supply pan 234 of a rear surface coating device and a supply pan 224 of a front surface coating device. During preliminary operation before escaping operation, a liquid is separately charged into a front surface escape route c for the liquid to be escaped to a reserving tank 506 from the surface coating device, and a rear surface escape route d for the liquid to be escaped to the reserving tank 506 from the rear surface coating device. |
