Abstract
Non-contact, gas-ejecting bearings () are provided for conveying flexible glass sheets (), 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 () from a plenum which operates at a pressure Pand the bearings have a calculated static pressure Pat the midpoints () between the bearing's centermost orifice () and each of its nearest neighbors () in a horizontal direction which satisfies the relationship P/P≧0.05. The bearings () can reduce the time-averaged, peak-to-peak variation in the spacing between a LCD substrate () traveling at, for example, 60 meters/minute and the face () of the bearing () to less than 500 microns, thus reducing the chances that the substrate () will hit and be damaged by the bearing ().
