PURPOSE:To adjust freely the plating metal deposition on a metallic strip in the stage of subjecting the metallic strip to metal hot dipping by a meniscus coating method by providing a gate consisting of plural divided bodies to a nozzle aperture for a plating metal and closing partially the aperture thereby controlling the passage rate of the molten metal. CONSTITUTION:The gate 3 consisting of the plural divided bodies 4 is provided to the aperture 2 of a nozzle 1 of a molten metal vessel 8 plating and the bodies 4 are made vertically slidable by means of an actuating rod 6 fixed to the upper part of the gate. The metallic strip 13 is moved upward by a deflector roll 12 in front of the aperture 2 of the nozzle 1 and is plated by the molten metal 7 for plating sucked out of the aperture 2 of the nozzle 1. Part of the bodies 4 are partially lowered by the rod 6 to close partially the space in the part of the gate 3, by which the passage rate of the molten metal for plating through the nozzle is controlled and the plating metal deposition on the metallic strip 13 is freely adjusted.
