Abstract
The present invention relates to a method of shaping a glass sheet in one dimension, by roll forming in a manner to selectively minimize/eliminate undesired curvature from the 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, optionally, by varying the velocity of the glass sheet as it moves through the shaping zones, thus varying the time portions of the glass sheet are in contact with certain shaping rolls.
