Abstract
A meander control is performed by using: a guide roller that alters the conveying direction of a aluminum sheet conveyed along a conveying path; a first edge sensor that detects the amount of meandering at a first detection position that is upstream of the guide roller; a second edge sensor that detects the amount of meandering at a second detection position between the first edge sensor and the guide roller; and a control device that calculates an error contained in a first gain of a first feedforward model on the basis of a detected value from the first edge sensor and a detected value from the second edge sensor, and corrects a second gain of a second feedforward model by the calculated error, and then calculates a guide position-estimated amount of meandering on the basis of the second feedforward model and the detected value from the second edge sensor.
