Abstract
A meandering amount detection method for a metal strip traveling in a state of being overlapped in a plurality of stages, includes: calculating an end portion position in a width direction of a metal strip in each stage using an angle formed by a reference direction, which is any direction determined from a reference point, and a direction connecting the reference point and an end portion position in a width direction of a metal strip in each stage, a distance between the reference point and an end portion position in a width direction of a metal strip in each stage, and a distance between a straight line including a width direction of the metal strip and the reference point; and calculating a meandering amount of a metal strip in each stage based on the calculated end portion position in the width direction of the metal strip in each stage.
