PURPOSE:To improve the accuracy of thickness by deciding the output timing based on the deviation time of output timing and whether the deviation of the thickness on the outlet side is plus or minus and adding or subtracting the lag time to or from the output timing in accordance with that result. CONSTITUTION:The arithmetic part 12 for the optimum timing receives the measured values from the thickness gage 5 on the inlet side and the thickness gage 6 on the outlet side and decides whether the output timing is earlier, later or proper. This optimum timing that is calculated with the arithmetic part 12 is outputted to a feedforward controller 9 and the output timing is changed and adjusted in a proper state automatically. In this way, the output timing can be easily adjusted in the optimum state and also the accuracy of thickness is improved. |
