Abstract

PURPOSE:To roll flat thin plate by uniforming the widthwise tensional distribution of plate by the procedure in which movable roller is fixed in place,crown for movable roller and fixed roller at which the constant elongation point of rolled material comes on the line where end elongation rate is zero is obtained, and then the crown is given to each roller. CONSTITUTION:When the crown of the fixed roller 16 is changed under the condition that the tension of the rolled material 18 is constant, the distribution of the widthwise tension of plate is uniform, and the movable roller 17 of the bridler 15 is fixed at the position of a turning angle a which corresponds to the constant elongation rate point 24, the constant elongation rate point 24 comes near the movable roller-crown line 23. When the crown amount of the fixed roller 16 and the crown amount of movable roller, corresponding to the intersection point 27, are obtained and they are given to respective rollers, the rolling of the material 18 of an end elongation rate epsilon of zero, or the flat material 8, can be performed with the uniform widthwise tensional distribution of plate from the start of winding the coil 13 to the completion of winding.
