PURPOSE:To perform constant and stable meandering controls independent of variations in width, etc., by adding a device changing control gains in accordance with the width and material of a rolled stock to a regulator outputting draft correction signals. CONSTITUTION:A computer 25 changing control gains is connected to a meandering controlling regulator 21 outputting draft correction signals 23, 24. As for a meandering amount of a rolled stock, a computing element 18 finds a difference between each signal from end position detectors 17a and 17b. The meandering amount and the target signal from a setter 19 are compared by a comparison computing element 20, the regulator 21 processes a obtained meandering deviation signal 22 and outputs draft correction signals 23, 24 to perform a meandering regulation. In that time, the constant and stable controls without relation to variations in width. etc., are performed because the computer 25 changes control gains of the regulator 21 in accordance with width, material, etc. |
