    摘要: PROBLEM TO BE SOLVED: To automate the changing of a sheet thickness in sheet forming using a touch roll or the like. SOLUTION: The take-up speed of the sheet under forming the sheet and the thickness of the formed sheet are each measured, the thickness of the sheet input by an operation board 55 is taken into the control device 50 when changing the thickness of the sheet. The take-up speed of the sheet after changing the thickness of the sheet is calculated by the control device 50 according to the operational expression Va=Vb (Tb/Ta) and the take-up speed of the sheet is controlled by the operational value. Wherein, Va: a take-up speed of the sheet after being changed, Vb: a take-up speed of the sheet before being changed, Ta: a thickness of the sheet after being changed, and Tb: a thickness of the sheet before being changed.

    摘要: PROBLEM TO BE SOLVED: To stably manufacture a sheet of a high product quality under accurate roll clearance settings through minimizing the variation of the roll clearance due to the inevitable fluctuating vibration in a feedback control and making the above measure and a highly precise position control stand together. SOLUTION: At the time of changing the control target values of the roll clearance, the roll position control is conducted from the position information detected by the linear scales 42R and 42L. When the deviation between the control target values after the change of the control target values and the roll position measurement values by the linear scales 42R and 42L falls below predetermined values, the roll position control is performed from the positions of the driving means detected by the piston displacement gages 41R and 41L that have a higher resolution than that of the linear scales 42R and 42L.
