Abstract

PURPOSE: To plate a strip to the coating weight uniform over the entire surface by adjusting the push-in of snap rolls according to the detected transverse warpage of the strip so that the space between the strip and wiping gas nozzles is made uniform.
CONSTITUTION: The strip 2 past a metal hot dipping bath 4 is leveled by the snap rolls 8 and is further wiped to the prescribed plating thickness by the wiping gas nozzles 10. A transverse warpage detecting means 16 which is a sensor of a non-contact type is provided in the transverse direction above the extreme neighborhood of the above-mentioned nozzles 10 in this stage. The signal from the means 16 is fed to a control arithmetic part 18 which calculates the distance between the strip 2 and the nozzles 10 and sends the result of the calculation to an operation part 20 of a mechanism for driving the rolls 8. The rolls 8 are thereby pushed in by as much as the required amt. in the direction where the warpage is offset. The operation of the rolls 8 is preferably executed with the lower roll in order not to change the pass line.
