Abstract
An apparatus for making a glass ribbon can include a heating plane including a heat footprint facing the surface of an edge director. A projection of the heat footprint in a resultant direction of the heating plane within the heat footprint can intersect the surface of the edge director. In further embodiments, a fusion draw method of making a glass ribbon can include radiating heat within a heat footprint of a heating plane toward a surface of an edge director. At least a portion of the heating plane within the heat footprint can face the surface of the edge director so that the surface of the edge director is intersected with heat radiating from the heat footprint of the heating plane.
