Abstract

The width of glass ribbon at the hot end of a float bath is controlled to a constant value by raising and lowering a tweel for adjusting the flow of molten glass blank from a smelting furnace to the float bath. The controlled value of the tweel is obtained from predetermined control variables through fuzzy inference. This method is carried out in a float-bath ribbon-width control system using a fuzzy inference means that obtains the controlled value of the tweel from predetermined control variables through fuzzy inference.
