<p>A method and apparatus for rolling a section in which flanges are provided connected continuously to a web. Rolls (15, 15", 16, 16") for expanding the web in the widthwise direction are provided between any steps during the process of rough rolling, intermediate rolling and final rolling. The rolls (15, 15", 16, 16") are in contact with the inner sides (21, 22) of the flanges. If required, the rolls (15, 15", 16, 16") may each engage with the corresponding upper and lower surfaces of the web. The shaft of each of the rolls (15, 15", 16, 16") is inclined at a predetermined angle TAUH with respect to the horizontal direction, perpendicular to the rolling direction. The shafts of the rolls (15, 15", 16, 16") are preferably inclined upward or downward at a predetermined angle TAUV with respect to the horizontal plane. </p> |
