ABSTRACT:
An apparatus for bending a glass sheet includes a final hearth bed. This final hearth bed has a top surface that is upwardly convexly curved along a plane perpendicular to an axis of the glass sheet. The top surface has an upstream end, a downstream end that is at a level lower than that of the upstream end, and an intermediate point defined therebetween. The top surface has (a) a first section that extends from the upstream end to the intermediate point and that is parallel with the axis or upwardly inclined relative to the axis and (b) a second section that extends from the intermediate point to the downstream end and that is downwardly inclined relative to the axis. The final hearth bed has a bottom surface that is along the first direction or inclined downwardly relative to the first direction.
