Abstract

PURPOSE:To achieve accurate adjustment of width of a strip, by providing a load meter between a screw and an inner housing and controlling a hydraulic cylinder basing on a signal from the meter. CONSTITUTION:When a strip 4 is rolled and the plate width becomes a set value or more, that is, when vertical rolls 20 are detached, a roll weight exerted on a screw 6 is increased. This is detected by a load meter 12, the signal is inputted to a comparison adder 30, oil is supplied to hydraulic servo valves 34 and 35, the hydraulic pressure in the cylinder of hydraulic cylinder mechanisms 18 and 19 is increased, the vertical rolls 20 are closed together to perform a screw down position control. If the width of the strip 4 is a set value or less, that is, the vertical rolls 20 are closed together, the rolling load of the screw 6 is decreased. The meter 12 detects it, a signal is inputted to the adder 30, oil is discharged from the servo valves 34 and 35, the vertical rolls 20 are mutually detached for the screw down position control.
