  • Patent number: 9670086
    Abstract: A glass manufacturing apparatus comprises a forming device configured to produce a glass ribbon and a control device configured to independently operate a first pull roll apparatus and a second pull roll apparatus such that at least one of a first upstream pair of draw rolls rotates with a substantially constant torque and at least one of a first downstream pair of draw rolls rotates with a substantially constant angular velocity. In further examples, methods of manufacturing a glass ribbon are provided.

  • Patent number: 9394193
    Abstract: An apparatus for drawing a glass ribbon including an edge roll assembly that contacts the glass ribbon with a force that is dynamically altered by an actuator electrically coupled to a sensor that measures the force applied against the ribbon. Dynamic, or real-time, variation of the edge roll force minimizes stress variability in the glass ribbon and improves ribbon shape control.

  • Patent number: 9061932
    Abstract: A pull roll apparatus and method are described herein that can control a cross-draw tension and a down-draw tension of a glass sheet while manufacturing the glass sheet. In one embodiment, the pull roll apparatus includes a first driven stub roll pair, a second driven stub roll pair and a control device (e.g., PLC) that controls the first and second driven stub roll pairs while a first edge portion of the glass sheet is drawn between two vertically downtilted rolls associated with the first driven stub roll pair and while an opposing second edge portion of the glass sheet is drawn between two vertically downtilted rolls associated with the second driven stub roll pair. If desired, the pull roll apparatus may include a pulling roll assembly (located below the first and second driven stub rolls) or another set of driven stub roll pairs (located below the first and second driven stub roll pairs).

  • Patent number: 7685841
    Abstract: In the formation of sheet glass by the overflow downdraw process, the width of usable sheet glass is maximized by downwardly flowing edge portions of the sheet over web-like members and thereafter over extensions which intersect with and are downwardly inclined relative to the web-like members to thin edge portions of the glass flow and maintain sheet width. The extension members are preferably removably attached to the web-like members, greatly facilitating replacement of the more easily damaged extension members.
