摘要： In a float process of flat glass production, the width of a glass ribbon formed by discharging a molten glass onto a molten metal bath is controlled in response to the temperature of a molten glass to be supplied to the molten metal bath by regulating a tweel to manipulate the rate of supplying a molten glass to the bath. Further to minimize a fluctuation of the glass ribbon width, either of two different feedback control modes, an integral control mode and a proportional-plus-integral control mode, is employed depending on whether or not an error between a measured width and a desired value is within a predetermined range of the error. Preferably the control is achieved in accordance with a sampled-data control system.
