发明名称 Glass lift mechanism for and method of press bending glass sheets
摘要 This invention relates to the handling of glass sheets that are supported by a conveyor along their bottom edges and balanced in an upright position for movement through a furnace, a shaping station and a cooling area. Means are provided to temporarily lift the glass sheet so that its entire extent is aligned with the facing shaping surfaces of a pair of shaping molds during shaping and returned to the bottom edge supporting conveyor which conveys the shaped glass sheet into the cooling area after it is shaped. Such treatment improves the contour of the bottom edge of the shaped glass sheet.
