PURPOSE:To control the meandering of strip in high accuracy by inclining every rotary shafts in the arbitrary same direction and controlling rotational speed at the arbitrary same speed about table rollers which are made to belong to the same group of the same zone. CONSTITUTION:About a steel sheet A which is transferred, meandering quantity is detected with a detector 60 on the inlet side of the (i)th zone, which is inputted to a correspondence arithmetic unit 50 and correction quantities W1, W2 of rotational speed are operated. The information of the correction quantities W1, W2 of rotational speed which are determined by that way respectively to the table rollers 12, 14 of each group are inputted into arithmetic and control systems 30, 32 for rotational speed as correction signals and rotational speeds W1, W2 after correcting the reference rotational speed W0 that is separately inputted from a control system 40 for reference rotational speed are determined. It is possible to revolve respectively the table rollers 12, 14 in the the (i)th zone at the rotational speed W1, W2 after correction by inputting control signals into motors M1, M2 which are individually connected from the control systems 30, 32 and controlling every rotational driving systems 22, 24 individually at proper rotational forces. |
