Abstract
A heat softened glass sheet is conveyed directly from a heating furnace onto an advancing conveyor belt which is supported on a scissor table. The glass sheet is advanced on the belt to a position below an upper press face. The scissor table increases the sag of the belt and the corresponding curved configuration of the supported glass sheet as it lifts the glass sheet into pressing engagement with the upper press face. During pressing, the glass sheet and belt generally conform to the shaping surface of the press face.
