  • Patent number: 4830649
    Abstract: An apparatus and method for bending glass sheets. In a first embodiment a heated glass sheet is moved into a bending section by rollers which are retracted to drop the heated glass sheet onto a mold where the glass sheet sags into a desired bent shape, then quenched between quench heads and lifted off the bending mold up to the upper quench head by air pressure, the rollers then close beneath the glass sheet and the glass sheet is deposited onto the rollers for conveying to a cooling station. In a second embodiment, the hot bent glass sheet is transferred on a mold from a bending section by a first shuttle to a position between the quench heads for quenching then removed from the mold by blowing air through the lower quench head until the glass sheet contacts an upper second shuttle which is transported to a blow-up section where the sheet is lowered onto a roller conveyor to a cooling section.
