Abstract

A method of minimizing distortion in a glass sheet manufacturing process wherein the stress in a parent sheet of glass is measured along each edge of the sheet. The stress data is then used to develop a distortion predictor for predicting the in-plane distortion which sub-sheets of the parent sheet are likely to exhibit when the parent sheet is cut into pre-determined sizes. The in-plane distortion may be predicted based on criteria established by the glass manufacturer, or supplied by an original equipment manufacturer (OEM).
