Abstract
A meandering control device includes: a detector configured to detect a position of an edge of a web being conveyed in a width direction of the web; a corrector configured to correct a position of the web being conveyed in the width direction; and a controller including a digital filter configured to perform filtering on a position signal indicating the position of the edge detected by the detector to attenuate a noise component. The controller is configured to drive the corrector to correct the position of the web in the width direction based on the position signal after the filtering.
