<p>Apparatus and method for moving a glass mass, such as a glass sheet in horizontal attitude through a bending section of a heating oven. The glass sheet at a deformation temperature is imparted movement along the conveyor system including a plurality of rollers, and a gaseous flow at high temperature, having a flow speed which varies continuously across the width of the glass sheet, impinges on its lower surface to at least partially balance the weight of the glass sheet in regions requiring good optical quality.</p> |
