<p>PURPOSE:To eliminate resetting at a leveling regulation and to simplify the operation by storing a meandering amount at completion of manual leveling regulation for a roll as the target value and performing succeeding meandering controls by use of the target value. CONSTITUTION:At the time of completing an operation of a manual leveling regulator 25 for a roll, a meandering amount of a rolled stock 9 at that time is stored into a storage circuit 19 and is made to be the target value for succeeding meandering controls. That is, a computing a element 18 calculates a meandering amount based on signals detected by end position detectors 17a, 17b. A comparison computing element 20 compares the meandering amount with the target value in the circuit 19 and outputs a meandering amount deviation signal, which is processed by a meandering controlling regulator 21 and is made to be a draft correction signal to perform meandering controls. Therefore, resetting of the target value after leveling regulation is not required and the operation is simplified.</p> |
