PURPOSE:To improve the width accuracy by pressing the top surface of a strip in the vicinity of the gap between edge rolls by a downward pressing roll and performing a edging with a winding angle of the strip being kept at the time of edging for the strip. CONSTITUTION:Edger rolls 4 and 5 are pressed against both width ends of a strip 3 by an edger 6 installed between rolling stands 1, 2 performing finish rolling. A looper angle is adjusted by both a downward pressing roll 7 installed in the roll gap between edger rolls 4, 5 to press the top surface of the strip 3 and looper roll 9 installed to push up the strip 3 by a turning of a looper arm 8. In that method, the width accuracy is improved. |
