ABSTRACT:
Glass which is heated to a softened state is bent from a generally planar state to a curved form while being transported on a moving conveyor made up of a plurality of generally parallel belts. The contour of the conveyor varies from being generally flat adjacent the apparatus inlet to being significantly curved adjacent the apparatus outlet. The softened glass sags under its own weight to conform to the varying conveyor contour.
