安定される。 Since the first embodiment of the present invention has the above-mentioned configuration, the drying air c is distributed through each of the blowing holes 12a, 12.
Air jets Q and Q' are emitted from b, and each air pocket (1
5-1), (15-2), (15-3), (15-4)
Static pressures P 1 , P 2 , P 3 , and P 4 are generated within the air, and these static pressures become equal and act on the traveling wave a as a floating force, resulting in a floating wave of height h, which causes the dry air to blow out on the blowing side of the dry air blowing surface. In addition, compared to the conventional example having a series of spaces formed in the wave width direction, the fluctuation in the distribution of floating force in the wave width direction is significantly reduced, the meandering of the traveling wave a is reduced, and the running is stabilized.

The air pockets on both sides are extended to the outside of the side edges of the traveling wave, and the diameters of the air pockets on both sides are increased to equalize the static pressure in each air pocket, so the static pressure in each air pocket is equal to that of the traveling wave. It acts as a floating force for the wave, and the fluctuation in the distribution of the floating force in the width direction of the running wave is reduced, and the meandering of the running wave is prevented by the self-aligning action caused by the increase in the blowout pressure in the air pocket on the meandering side. This has effects such as improved floating running performance of the running wave and improved drying performance.
