ければならない。That is, in order to perform highly efficient plating on a very thin strip having a material to be plated of about 0.1 mm in a plating tank, a large flow rate of liquid must be supplied. Further, if the pulsation or vibration of the liquid is large, the pulsation or vibration causes wrinkles or breaks in the strip. Therefore, the liquid flow must be in a rectified state with very small pulsation or vibration. Further, when the plating thickness is controlled under a strict control standard, the flow velocity distribution in the width direction of the strip must be uniform.

である。The liquids merged in the primary nozzle chamber pass through the slit formed by the partition wall and the wall of the nozzle, flow into the secondary nozzle chamber, and are blown out from the jet port toward the strip 1. At this time, the slit 7 widens in a taper shape from the central portion A toward the liquid supply port vicinity B and B ′. That is, the structure is such that the liquid does not easily flow out from the central portion and the liquid easily flows out from the vicinity of the liquid supply port. Due to this structural consideration and the balance of the static pressure distribution in the nozzle chamber, a uniform flow velocity distribution can be obtained in the width direction of the nozzle.
