<p>PURPOSE:To prevent the generation of the unevenness of winding condition, winding flaw, buckling, etc. by detecting a real tension burdened on a metallic strip to be wound, and converting it into a control signal, and controlling a motor of coiler by comparing the signal with a set value. CONSTITUTION:A thin steel strip S is wound around a tension reel 1 of a coiler through a real tension measuring device 2 and a guide roll 4. The measured real tension F is inputted to a tension/electric-current converter 13 and is converted into a datum IF of electric current value and is inputted to an electric current conrol device 12. The device 12 compares the converted signal IF outputted from the converter 13 with a basic control signal which is an add signal outputted from an adder 11 which adds together the signals outputted respectively from a tension reference device 9 and an acceleration-deceleration compensation device 10. A motor 3 of reel 1 is controlled so that both signals are equal to each other. In this way, the real tension in winding is kept constant.</p> |
