Abstract
Disclosed herein are systems for shaping a glass sheet comprising a roll conveyor comprising a plurality of rollers for conveying the glass sheet along a plane; a lift jet array comprising a plurality of nozzles, one or more of the plurality of nozzles comprising a tip having a plurality of orifices; and a shaping mold located above the roll conveyor, wherein the lift jet array is positioned below the roll conveyor such that each nozzle tip is located above the centerline of the plurality of rollers. Also disclosed herein are methods for shaping a glass sheet comprising heating the glass sheet and conveying the glass sheet on a roll conveyor to a position between the lift jet array and the shaping mold, wherein gas flows from the lift jet array with a force sufficient to lift the glass sheet from the roll conveyor.
