摘要

PROBLEM TO BE SOLVED: To provide a device and a method for grinding a metallic belt capable of preventing a crack and a rupture of an end part in the direction of width of the metallic belt in the next cold rolling process even after the metallic belt like a thin cold rolled steel belt having a thickness of 0.8 mm or less is ground. SOLUTION: This grinding device 1 is provided with a tension providing means 4 flattening the metallic belt S by providing a tension having a predetermined value for the metallic belt S and a grinding means 5 grinding the metallic belt S flattened by the tension providing means 4 by applying a tension having a predetermined value. Preferably, a scope of the predetermined value of tension is 70 to 250 Mpa.
