Abstract
Provided is a strip crossbow reduction and vibration reduction method (strip stabilization method) including of controlling an exciting current to an electromagnet based on a distance to a strip being conveyed, the first distance being detected by a displacement sensor, and performing crossbow reduction and vibration reduction on the strip by means of an electromagnetic force of the electromagnet. The method is characterized in that the exciting current applied to the electromagnet is controlled based on the distance and a target position corresponding to the distance, and that the exciting current is applied to the electromagnet when the strip is present within detectable range of the displacement sensor whereas the exciting current is not applied to the electromagnet when the strip is not present within the detectable range of the displacement sensor.
