摘要：PURPOSE:To improve winding of the front end of a steel strip on a coiler by pulling the front end of the steel strip on a pass table at a high speed to eliminate the waving thereof and exerting back tension thereto if the waving cannot be thoroughly absorbed. CONSTITUTION:A waving detector 12 calculates tracking length and calculates at the same time the waving quantity at the front end of the steel strip 1 when the mill bite signal M2 from a bite detector 11 and the revolving number signal M1 from an encoder 10 are inputted thereto and further when the detection signal K1 for the front end of the steel strip from a detector 5 is inputted thereto. If the waving quantity is larger than a reference value, a command signal R2 for absorbing the waving is outputted from the detector 12 and is inputted to a speed controller 16 for a rear table which increas the conveying speed of a rear pass table 8, thereby absorbing the waving. The front end of the strip 1 is further detected by a detector 6 just prior to winding on a coiler 4 and the signal thereof is inputted to a waving detector 15 which calculates the waving quantity and compares the same with a reference value. The back tension is exerted to the front end of the strip 1 to absorb the waving by decreasing sharply the speed of the table 8 when said value is larger than the reference value.
