  • Patent number: 10570047
    Abstract: A method of continuously processing glass ribbon having a thickness ?0.3 mm. The method includes providing a glass processing apparatus having a first processing zone, a second processing zone and a third processing zone. The glass ribbon is continuously fed from the first processing zone, through the second processing zone to the third processing zone. The feed rate of the glass ribbon is controlled through each processing zone using a global control device. A first buffer zone is provided between the first processing zone and the second processing zone in which the glass substrate is supported in a first catenary between two, spaced-apart, payoff positions. A second buffer zone is provided between the second processing zone and the third processing zone in which the glass substrate is supported in a second catenary between two, spaced-apart, payoff positions.

  • Publication number: 20180141848
    Abstract: A method of continuous processing of flexible glass ribbon having a thickness of no more than 0.35 mm using a glass processing apparatus. The method includes providing the glass processing apparatus having at least three processing zones, including a first processing zone, a second processing zone and a third processing zone. The flexible glass ribbon is continuously fed from the first processing zone, through the second processing zone to the third processing zone. The feed rate of the flexible glass ribbon is controlled through each of the first processing zone, the second processing zone and the third processing zone using a global control device. Lateral position of the flexible glass ribbon is controlled through the second processing zone using a multi-axis steering apparatus comprising a first roller set and a second roller set, located downstream of the first roller set.

  • Patent number: 9682882
    Abstract: Methods for producing a glass ribbon include the step of drawing a glass ribbon from a quantity of molten glass and detecting an instability in the glass ribbon. In response to the detected instability, the method can further include the step of automatically adjusting an operating variable for each of a plurality of stabilizing elements simultaneously with a controller to at least partially counter the detected instability.
