Abstract: In order to produce sheet glass of a thickness less than normal equilibrium thickness from a layer of molten glass deposited on a fluidic support, a solid structure with a plenum chamber is positioned above the support while air or other gas under pressure is discharged from the plenum chamber, through a peripheral slot, in a downwardly converging gas curtain which builds up a pressure head in the space between the support and the flat underside of the structure. This pressure head may be utilized to balance the weight of the overlying structure for floatingly maintaining same above the support in spaced relationship with the glass layer deposited thereon.

This pressure head may be utilized to balance the weight of the overlying structure for floatingly maintaining same above the support in spaced relationship with the glass layer deposited thereon. By providing several generally concentric peripheral slots through which the gas is discharged in successive stages, starting with the innermost slot, or by making the structure adjustable to allow a shifting of its slot-forming gap, the air curtain may be expanded laterally or possibly omnidirectionally to reduce the width of the beads bounding the thinner central portion.
