Abstract:
A fusion draw apparatus includes a pair of engagement rollers. At least one of the pair of engagement rollers includes a circumferential knife edge configured to cooperate with the other of the pair of engagement rollers to thin the edge portion or sever the edge portion from a central portion of the glass ribbon within the viscous zone of the glass ribbon. In further examples, fusion draw methods include the step of thinning the edge portion or severing the edge portion from the central portion of the glass ribbon within the viscous zone.
