Abstract
Methods and apparatuses for fabricating continuous glass ribbons are disclosed. The method includes forming the continuous glass ribbon by drawing the continuous glass ribbon from a draw housing in a drawing direction, heating at least one portion of a central region of the continuous glass ribbon at a heating location downstream of the draw housing, sensing a temperature of the continuous glass ribbon at a sensed temperature location downstream of the draw housing, and automatically controlling the heating of the at least one portion of the central region of the continuous glass ribbon based on the sensed temperature to mitigate distortion of the continuous glass ribbon.
