Abstract
PURPOSE:To sufficiently execute the forming of both edges of even a thick and thin material by constituting the lower grooved roll of the horizontal roll of one stand by two rolls and making the inclination in the metal strip progressing direction adjustable. CONSTITUTION:In at least one horizontal stand mainly in charge of the bending of an edge a lower roll 3 is composed of two rolls 5, 5 having an inclination beta(inclined angle) for the feeding direction of a metal strip 4. Since each lower roll 5 has the inclination beta at the contact point of the lower roll 5 and metal strip 4 it is moved together with the progress of the bending of the metal strip 4, the position is varied and a concentrated load is not received at one point. The edge thickness reduction of the metal strip 4 is not generated, the bending to the edge of the metal strip 4 can be executed sufficiently and no roofing is thus caused.
