1. A method for fabricating a continuous glass ribbon, the method comprising:
forming the continuous glass ribbon by drawing the continuous glass ribbon from a draw housing in a drawing direction, wherein the continuous glass ribbon comprises a central region, a first bead portion, and a first near bead region laterally positioned between the first bead portion and the central region, wherein the central region comprises a first lateral region and a second lateral region; heating the first lateral region of the central region and the second lateral region of the central region at a heating location downstream of the draw housing; sensing a first near bead temperature within the first near bead region, sensing a first lateral region temperature within the first lateral region of the central region, and sensing a second lateral region temperature within the second lateral region of the central region at a sensed temperature location downstream of the draw housing; controlling, automatically, the heating of the first lateral region of the central region of the continuous glass ribbon based on a first temperature difference between the first near bead temperature and the first lateral region temperature to mitigate distortion of the continuous glass ribbon; and controlling, automatically, the heating of the second lateral region of the central region of the continuous glass ribbon based on a second temperature difference between the first near bead temperature and the second lateral region temperature to mitigate distortion of the continuous glass ribbon. |
