摘要： 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.

摘要： A thermal edge finishing process includes preheating at least one cut edge of a glass sheet, laser finishing the edge to a single full continuous radius from a position orthogonal to the edge and in-plane with the glass sheet while continuing to heat the glass, and localized annealing of the edge to reduce residual stress from the laser/thermal treatment of the edge. By the present process, edge stress is reduced considerably, such as to less than 3000 psi, and more preferably to less than 2500 psi, and to as low as 1000 psi in the first 1 mm along the treated edge.

摘要： Non-contact, liquid-ejecting bearings (3) are provided for conveying flexible glass sheets (13), such as LCD substrates, at high conveyance speeds, e.g., speeds of 15 meters/minute and above. The operating parameters and physical properties of the bearings satisfy at least one of the following conditions: (a) the average flow rate from the bearing's orifices (22) is in the range of 100-800 milliliters/minute/orifice; (b) the orifices' average horizontal pitch (P) is in the range of 20-55 millimeters; and/or (c) the orifices' average size (e.g., D0) is in the range of 1.0-4.5 millimeters. The bearings (3) can reduce the time-averaged, peak-to-peak variation in the spacing between a LCD substrate (13) traveling at 15 meters/minute and the face (20) of the bearing (3) to less than 100 microns, thus reducing the chances that the bearing (3) will lose control of the substrate (13) or that the substrate (13) will hit the bearing (3).

摘要： Methods and apparatus are disclosed for etching flexible glass sheets (13) in which the sheets (13) are transported in a vertical or near vertical orientation past non-contact, liquid-ejecting bearings (3) which apply an etching solution (e.g., an aqueous NaF/H3PO4 solution) to one or both sides of the sheets (13). In certain embodiments, the uppermost liquid-ejecting bearing (3) is above the top edge of the sheet (13) and thus is able to apply etching solution to the top of the sheet. In other embodiments, a top shower (11), which includes a set of spray nozzles (21) located above and distributed along the length of the apparatus, is used to apply etching solution to the top of the sheet (13). Using the disclosed methods and apparatus, glass sheets (13) produced by a fusion process are provided which have areas greater than five square meters and average surface roughness values in the range of 0.5 nanometers to 1.1 nanometers.

摘要： Non-contact, gas-ejecting bearings (3) are provided for conveying flexible glass sheets (13), such as LCD substrates, at high conveyance speeds, e.g., speeds of 40 meters/minute and above, e.g., 60 meters/minute. Gas is provided to the bearing's orifices (22) from a plenum which operates at a pressure Pplenum and the bearings have a calculated static pressure Pmidpoint at the midpoints (27) between the bearing's centermost orifice (26) and each of its nearest neighbors (28) in a horizontal direction which satisfies the relationship Pmidpoint/Pplenum≧0.05. The bearings (3) can reduce the time-averaged, peak-to-peak variation in the spacing between a LCD substrate (13) traveling at, for example, 60 meters/minute and the face (20) of the bearing (3) to less than 500 microns, thus reducing the chances that the substrate (13) will hit and be damaged by the bearing (3).
