  • Thermal tensioning during thermal edge finishing
    Publication number: 20080041833
    Abstract: A thermal edge-finishing process includes pre-heating an edge of a glass sheet, focused heating inboard of the edge to cause thermal tensioning, laser finishing the edge, and localized annealing of the edge. By stress cancellation, the thermal energy added by a laser edge-finishing operation does not result in as much residual stress. By the present process, residual stress is reduced to below 3000 psi, and more preferably to about 1000 psi, and as low as 600 psi in the first 1 mm along the treated edge.
