Abstract
PURPOSE:To improve a product in quality and accuracy by fitting a rocking device to obliquely move a flange correcting roll together with a flange holding roll and arranging a movable correcting mechanism composed of web holding rollers. CONSTITUTION:The flange correcting mechanism 10 is composed of the flange correcting roll 11, the flange holding roll 12 and 1st and 2nd web holding rollers 17, 18. The rolls 11, 12 are fitted to a rocking frame 19 and moved obliquely together with a sectorial rack 19a, a pinion 14 and an angle adjusting motor 16. The web holding roller 17 is moved vertically by a height adjusting cylinder 39 and the holding roller 18 is arranged on the same line with the web holding roller 17. In this mechanism the correcting angle is set finely by the oblique motion of the rocking frame 19 and corrected by driving the flange correcting roll 11, the holding roll 12 and the web holding rollers 17, 18. In this manner, the product is improved in quality and accuracy.
