PROBLEM TO BE SOLVED: To provide a water feeder for a sealing section used for stabilizing the sealing quality by making the air pressure constant all through from the flap atomizing starting end to the completing end and blowing off water drops adhered on nozzles. SOLUTION: Air from a compressor is changed over by a three-way valve, and in the case the air is atomized to a flap, the air is introduced to the atomizing nozzle side, while the air is introduced to the exhausting side in other cases to conform the atomizing air pressure to the exhausting air pressure. Also the air is jetted from an exhaust nozzle to blow off water drops adhered to the end of the sealed atomizing nozzle to realize the good sealing quality.
