As shown in the figure, this device is a wiping device that includes a wiping nozzle 6, a header 7, and a gas supply box 8 having a gas inlet in that order.
Is provided to form a plurality of gas distribution chambers 10, and an opening / closing device 11 is installed at the inlets thereof. The gas introduced into the gas supply box 8 through the gas inlet is the opening / closing device 1
The pressure is adjusted by 1 and the pressure is introduced to each flow dividing chamber 10. Then, the gas is sent to the wiping nozzle 6 while maintaining its pressure, and is ejected to the strip through the nozzle slit at the tip thereof. In this device, a pressure distribution exists in the strip width direction when the gas is ejected from the wiping nozzle 6, and by controlling this distribution, it is intended to give a uniform basis weight regardless of the steel plate shape or the like. .

着量は均一なものになる。FIG. 1 shows an example of the present invention. The gas introduced into the header 1 is guided to the introduction pipe 2 with a uniform pressure and a uniform pressure. However, the pressure control device 3 (as long as the pressure can be adjusted, a valve is used as an example in FIG. 1). However, this is not the case), and the pressure is adjusted to a different predetermined pressure for each introduction pipe. As a result, the gas flows into the gap 4 in the gas wiping nozzle 6 at different pressures in the width direction of the nozzle 5, but the pressure is made uniform to some extent by the interaction in the gap, and the pressure distribution becomes smooth. Then, the gas is blown to the plated steel sheet through the gas wiping nozzle 5 with this uniformed pressure. The spraying pressure at this time is adjusted by the pressure control device 3 according to the state of the plated steel sheet (for example, the degree of warpage), so that the amount of deposited plating becomes uniform.
