ABSTRACT:
Thin substrates, such as flat glass panels, are levitated on a porous media air bearing creating a pressurized film of air and preloaded against the air film by negative pressure areas. The pressure can be distributed most uniformly across the pressure areas by defusing the pressure through a porous medium. Such a bearing can be used for glass flattening by holding the glass such that the unevenness is migrated to the side opposite the side to be worked on.
