PURPOSE:To permit easy formation of a tapered flange material, the flange width of which changes continuously, by providing shaping rolls of an edging mill in such a manner that the caliber depth in the flange rolling down part of said rolls can be adjusted according to the width of the flange. CONSTITUTION:The shaping rolls 15 of the edging mill are fitted into roll main shafts 16 and are so provided that the gap between the right and left rolls can be freely adjusted by means of liquid pressure cylinders, etc. An intermediate eccentric rolls 18 are freely rotatably mounted to the outside circumference of the shaping rolls 15 and are provided in such a manner that said rolls can be actuated independently from the adjustment of the above-mentioned roll gap by eccentric ring position setters 20. The roll gap thereof is online controlled according to a prescribed program by which the caliber depth in the flange rolling part is adjusted and the rolling is thus executed. The shape material, the flange width of which changes continuously in the longitudinal direction, is, therefore, easily formed with high accuracy. |
