Abstract
An apparatus for processing glass sheets includes a furnace and a bending station traversed by a conveyor for carrying the glass sheets. A plurality of heaters mounted in the furnace each heat associated areas of the glass sheets in accordance with setpoint temperature signals representing desired values of temperatures for heating associated areas of the glass sheets. One or more parameters of the glass sheets, such as thickness and color, are sensed and the setpoint signal values are changed accordingly. The parameter values are also utilized to change the spacing between the upper and lower mold members in the bending station to adjust the bending pressure applied to the glass sheets. Furthermore, the parameters are utilized to change the speed of the conveyor sections in order to vary the time that the glass sheets are in the furnace and thus the amount of heat imparted to the glass sheets.
