  • Method of shaping glass sheets
    Patent number: 8752403
    Abstract: A method is provided for shaping a glass sheet in more than one dimension, and within the one or more dimensions forming non-uniform shapes between, for example, the leading edge and the trailing edge of the same glass sheet. Such shaping is achieved by the selective location, in first and second shaping zones, of shaping rolls having first and second shaping configurations and by varying the speed of the glass sheet as it moves through the shaping zones, thus varying the length of time that selected portions of the glass sheet are in contact with certain shaping rolls.
