【発明の名称】熱軟化可能な板材料の造形方法及び装置
Document Type and Number:
Japanese Patent JP2677329
Kind Code:
B2
Abstract:
A heat softened glass sheet (G) is conveyed directly from a heating furnace (12) onto an advancing conveyor belt which is supported on a scissor table (30). The glass sheet (G) is advanced on the belt to a position below an upper press face (28). The scissor table (30) increases the sag of the belt and the corresponding curved configuration of the supported glass sheet (G) as it lifts the glass sheet (G) into pressing engagement with the upper press face (28). During pressing, the glass sheet (G) and belt generally conform to the shaping surface of the press face (28).
