  • Method and apparatus for bending glass sheets
    Patent number: 5286271
    Abstract: Glass sheets are heated to their heat softening temperature and transferred to a shaping station having an upper vacuum mold with a downwardly facing shaping surface corresponding to the desired shape of the glass sheet. The glass sheet is lifted into engagement with the shaping surface and held thereagainst by vacuum. The mold and the glass sheet are then moved to a transfer station and the vacuum is released to deposit the shaped glass sheet onto a contoured conveying surface which generally conforms to the shaped glass sheet. The glass sheet is deposited onto the contoured conveying surface as it is moving from the shaping station to the transfer station to impart movement in the glass sheet along the contoured conveying surface and minimize marring of the glass sheet as it contacts the contoured conveying surface.
