Abstract

A steel-sheet snaking preventing device for a vertical looper includes a jack mechanism provided at each of at least two corners of a looper carriage and coupled via a metal fitting to a chain or a wire rope that pulls the looper carriage; a tilt meter configured to detect the amount of tilt of the looper carriage; a level meter configured to detect a height of the looper carriage; and a means for receiving detection signals from the tilt meter and the level meter, determining the amount of tilt of the looper carriage at which the amount of snaking of a steel sheet becomes zero, sending the determined amount of tilt of the looper carriage as a command to the jack mechanism, and controlling the amount of tilt of the looper carriage by the jack mechanism.
