ABSTRACT:
An apparatus capable of accurately forming a heated glass sheet to a deep, abrupt, or complex curvature are disclosed as utilizing a first curved mold (42) that initially forms the glass sheet at a first forming station (20) preferably by the operation of gravity. The initially formed glass sheet is moved horizontally preferably by movement on the first curved mold (42) to a second forming station (22). A second curved mold (48) of the second forming station (22) engages the initially formed glass sheet to provide accurate forming preferably by downward movement of the second curved mold that provides the engagement thereof with the glass sheet. In the preferred construction disclosed, the heated glass sheet is transferred from a furnace conveyor (28) to a topside conveyor (32) for depositing onto the first curved mold (42), and a transfer conveyor (55) transfers the formed glass sheet from the second curved mold (48) to a quench station (24) for tempering.
