PURPOSE: A device of correcting belt-meandering is provided to minimize stress applying to the material transferred with high speed even through simple structure, and to more accurately correct belt-meandering. CONSTITUTION: A device of correcting belt-meandering(100) comprises a driving part(110), an upper and a lower rollers(120,130) transferring materials by rotating by rotational force from the driving part, a support part(150) supporting the rotation shafts of the driving part, the upper roller and the lower roller, and a transverse moving device for moving the support part toward the right angle direction of the materials, and additionally a belt-meandering sensor(135) for detecting the meandering of the materials, and a control part moving the support part toward the meandering-corrective direction by controlling the transverse moving device in case of detecting the meandering of the materials by the belt-meandering sensor. |
