PURPOSE:To roll flat thin plate under a condition that the distribution of tension in the direction of width of plate is uniform by the procedure in which a fixed crown is given to fixed roller, movable roller is turned to obtain the position of movable roller crown and turning angle where end elongation rate becomes zero, and rolling is made by giving the crown to the movable roller. CONSTITUTION:When a fixed crown is given to the fixed roller 16 of the bridler 15 and also a crown amount is given to the movable roller 17 which corresponds to the point 23C given at the intersection point 24 shown in the Fig. relating the crown amount of the movable roller 17 to the end elongation rate epsilon of the rolled material 18 under a condition that the position of the movable roller 17 is fixed in place at a fixed turning angle alpha and the width-wise tensional distribution of the rolled material 18 at a fixed tension is uniform, rolling is made constantly with the end elongation rate epsilon of the rolled material 18 which corresponds to the point 25 given at the intersection point 24 from the start of winding the coil 14 to the completion of winding. |
