Abstract

PURPOSE: To utilize the crown effect of roll for uniformalizing the lateral elongation of strip, and to correct the shape of strip into good conditions, by gradually changing the outer diameter of roll on the run-out side of each of tension roll group and camber correcting roll group, from the end to the middle of roll drum.
CONSTITUTION: In the tension roll group 14, 15 and the following camber correcting roll group 16, 17 both being arranged between the feed-in side and the run-out side anticrimping rolls 12 and 13, both of the run-out side roll 15 of the tension roll group and the run-out side roll 17 of the camber correcting roll group are made as a convex crown roll wherein the effective outer diameter of roll is gradually changed as compared with the outer diameter of roll end. Hereby, in case of handling an annealed material, the crown effect of roll 15 is canceled by the following roll 16, and the effect of crown shape of the roll 17 further shortens pathway of the side edge of strip 11, so that the lateral elongation of strip becomes uniform and the shape of strip is improved. In case of a full-hard material, the crown effect of roll 15 corrects the shape of strip 11 similarly to above.
