ABSTRACT:
A method for producing, from metal strip, a cold roll formed shape strip, curved longitudinally a predetermined amount and having its edge portions on the concave side of the curvature and its web on the convex side thereof to inhibit elongation deformation of portions of the metal strip which constitute the edge portions of the shape strip. The method includes a first step of subjecting the metal strip to roll forming to effect shaping thereof, while advancing the metal strip, under conditions of changing gradually the height of the point of contact between metal strip to be formed and rolls of each cold forming roll stand, and a second step of subjecting the roll formed shape strip to roll forming to curve the same longitudinally thereof to give thereto a predetermined radius of curvature, under conditions of changing gradually the height of the point of contact between roll formed shape strip and rolls of each cold forming roll stand in the reverse direction to the first step, while simultaneously effecting roll forming from multiple directions at least as part of the second step.
