もとづいて開度調整を行う等の方法が知られている。By the way, in order to achieve the above purpose, it is necessary to properly adjust the opening degree of the side guide, and conventionally, it is necessary to adjust the opening degree of the side guide appropriately. Either gradually adjust the opening of the side guide, or, as shown in Japanese Patent Laid-Open No. 55-10316, the actual width of the strip is detected by a finishing width gauge installed on the finishing rolling mill. A method of adjusting the opening degree based on the detected value is known.

な調整が達戒されないという問題があった。(Problem to be Solved by the Invention) By the way, if the opening degree of the down coiler side guide device is improperly adjusted, it not only causes damage such as wear and gouges on the side guide surface, but also damages the coil edge. In addition to the occurrence of ear flaws caused by unevenness, poor winding, or side guides, which impede manufacturing operations, further damage to the ears may occur during transportation on a conveyor crane or during processing in the next process. This results in the occurrence of defects and a decrease in product yield. However, as explained above, the conventional adjustment method depending on the operator's visual sense or the adjustment method using the actual measurement value of the width gauge at the exit side of the finishing rolling mill has a problem in that appropriate adjustment cannot always be achieved.
