Abstract
PURPOSE: To make stable operation possible despite the occurrence of any slip between the press rollers attached with speed detectors of steel strip and a steel strip by obtaining the coil diameters on the uncoiler and coiler side from the ratios of the respective revolutional numbers of the uncoiler and coiler and controlling said ratios.
CONSTITUTION: A steel strip 1 is uncoiled from an uncoiler 2 and is coiled by a coiler 3. The machines 2, 3 are driven by motors 4, 5 respectively, and the tension and steed of the steel strip are made constant by current and speed control devices 6, 7. Here, the revolutional numbers of the machines 2, 3 are detected by detectors 13, 14, and the ratios thereof are operated by a device 15. From these ratios, the coil diameters D1, D2 on the machine 2, 3 side are operated by a device 16. A speed reference generator 9 applies the rotating speed reference value of the machine 5 to the device 7 by using the diameter D2 obtained by the device 16. The device 7 controls the rotating speed of the detector 12 in such a manner that it coincides with said value. Also, the device 6 controls the current of the machine 4 in such a manner that it coincides with the reference value from a current reference generator 8; at the same time, it controls the field current by using the diameter D1 in such a manner that the field flux ϕ of the machine 4 assumes D1∝ϕ.
