High-velocity gas blown from the gas outlet 4, after leaving the gas guide face 3, but mostly to reflux for redirecting the return path 8, to reach the small amount Tsukisusumi following nozzle member 2 Sometimes. However, the gas that has reached the next nozzle device 2 merges with the gas blown out from the next nozzle device 2, so that the gas layer passing through the gas guide surface 3 of the next nozzle device 2 is thickened and the flying size of the sheet S rises. Will be increased. As a result, the area of the negative pressure generated on the gas guide surface 3 of the next nozzle member 2 becomes unstable, and the sheet S may flutter up and down. Since the gas that moves forward accumulates one after another, the sheet S flaps violently particularly at the nozzle member 2 at the final end .
