PURPOSE: A method and an apparatus for controlling buckle of strip are provided to prevent damage of the roll and tear of the strip so that stopping of plant is prevented by actually measuring buckle portion of strip and automatically opening or closing roll of the plating and rolling equipment accordingly. CONSTITUTION: The apparatus comprises a front buckle detecting and judging part(11) for sending the comparison judgement processed data to comparison judgement part and distance measurement operation part(12) after performing comparison judgement processing of buckle generation by operating a difference between a set value and actually measured voltage values from detected values transmitted from front buckle detecting sensor(7); a rear buckle detecting and judging part(14) for sending the comparison judgement processed data to the comparison judgement part after performing comparison judgement processing of buckle generation by operating a difference between a set value and actually measured voltage values from detected values transmitted from rear buckle detecting sensor(8); a distance measuring and operating part(12) for sending the comparison judgement processed data to the comparison judgement part by operating a difference between a set value (a fixed distance between the front buckle sensor and rolling roll) and detected values (buckle moving distance values transmitted from speed detector(9)) after operating distance values detected by the speed detector through signals transmitted from the front buckle detecting and judging part; and a comparison judging part for automatically opening the plating and rolling equipment by transmitting signals from hydraulic control part(4) if buckle generation is judged according to signals received from the front buckle detecting and judging part and the distance measuring and operating part, and automatically closing the plating and rolling equipment by transmitting signals to the hydraulic control part if it is judged that the buckle portion passes all through the plating and rolling equipment according to signals received from the rear buckle detecting and judging part.
