PURPOSE: An apparatus for controlling meander of strip is provided to remove line stop and work load of workers caused by twisting of the strip generated during trimming operation by measuring width of trimming chips, thereby preventing twisting of the strip. CONSTITUTION: In a strip meander controlling apparatus for measuring width of trimming chips(7) generated when cutting side of strip(1) by trimmer knives(3) mounted on trimmer knife blocks(2), the apparatus comprises a width measuring means(10) comprising a pair of rollers(17) installed on a proceeding path of the trimming chips with the rollers being spaced apart from each other in a certain distance, and first resolvers(14) for calculating displacement of the rollers moved according to width of the trimming chips(7) passing through the rollers into the width of the trimming chips; and a meander control means(30) installed on the proceeding path of the strip in rear of the trimmer knife blocks and equipped with rotation roller contacted with the side of strip to be proceeded to control meander of the strip by moving the rotation roller according to width values of the trimming chips supplied from the first resolvers in a traversing direction to the strip proceeding direction, wherein the meander control means comprises upper plate(31), moving plate(33), rotation motor and second resolver, wherein the strip meander controlling apparatus further comprises chip guiding means(20), the chip guiding means comprises a fixed base and a pair of guiding rollers(60), and a groove is formed on the outer circumferential surface of an intermediate part of one of the guiding rollers, and wherein the strip meander controlling apparatus further comprises a warping prevention means comprising supporting plate(90), cylinder(63) and pressing roller.
