Abstract

An apparatus for fusion drawing a glass ribbon includes a forming wedge with a pair of downwardly inclined forming surface portions converging along a downstream direction to form a root. The apparatus further includes an edge director intersecting with at least one of the pair of downwardly inclined forming surface portions, a heating device configured to heat an interface of the molten glass in contact with the edge director, and a cooling device configured to extract heat from a portion of the glass ribbon flowing off of the edge director. Methods are also provided for heating an interface of the molten glass in contact with the edge director and for extracting heat from a portion of the glass ribbon flowing off of the edge director.
