PROBLEM TO BE SOLVED: To provide steel strip cold-rolling equipment and a manufacturing method capable of precisely preventing the occurrence of wrinkles of an ultrathin steel strip when finishing hot-rolled steel strip into the ultrathin steel strip (foil) according to cold rolling.SOLUTION: Steel strip cold-rolling equipment includes: a cold-rolling machine which performs cold rolling of a steel strip; a tension reel which winds the cold-rolled steel strip; and a wrinkle suppressing roll which is provided between the cold rolling machine and the tension reel and prevents wrinkles of the steel strip form occurring. Therein, the wrinkle suppressing roll has a wrinkle suppressing roll main body which comes into contact with the steel strip and a roll deflection shape changing mechanism which changes a roll deflection shape in a width direction of the wrinkle suppressing roll main body.SELECTED DRAWING: Figure 3 |
