  • Apparatus for radiatively cooling glass sheets
    Patent number: 5096480
    Abstract: An apparatus (10) for cooling a glass sheet (G) formed on an upwardly facing full face male glass sheet shaping mold (12) disclosed includes a glass sheet press ring (14) mounted on a press ring enclosure (16). A freeze plate (18) having first and second surfaces (20,22) is mounted in the press ring enclosure. A cooling means (24) mounted adjacent the freeze plate (18) cyclically cools the freeze plate (18) between a heated ambient temperature and a temperature significantly below the glass sheet (G) whereby the freeze plate (18) radiatively cools the glass sheet (G) formed on the full face glass sheet shaping mold (12) by the press ring (14) sufficiently so that the formed glass sheet (G) shape does not change upon further processing.
