Abstract

PURPOSE: To accurately control a tension in a width direction all over the width of a stock by structurally controlling a pressing means to press each tension controlling roll to the respective stocks based on the detected result of the shape by a surface shape detecting means of the rolled stock.
CONSTITUTION: As the stock 12 i.e., a steel sheet is supplied by a supply reel 10 to a rolling mill 16, the rolled steel sheet 12 is taken up by a take-up reel 26. At this time, the tension of the steel sheet 12 impressed in its rolling direction is weakened on the outlet side of the rolling mill 16, a local deformation occurs, the shape of the steel sheet 12 becomes irregular and this irregularity is detected by a shape detecting means 30 to grasp the deformed shape of the steel sheet 12. Then, this detected signal is inputted to a controlling means and computed 32 and an arithmetic result is signalized and sent to a pressing means 36. Each tension controlling rolls 22aW22e are pushed to the steel sheet 12 based on this signal, a tension in a width direction is impressed to the steel sheet 12 according to the deformation of the steel sheet 12 and the steel sheet is taken up round the take-up reel without causing any fold or wrinkle.
