Abstract: A glass manufacturing apparatus includes a forming device that is configured to produce a glass ribbon that includes a width extending between a first edge and an opposite second edge of the glass ribbon. A lower draw roll apparatus includes a first pair of draw rolls arranged and configured to draw the first edge of the glass ribbon within a lower draw zone along the draw path. The lower draw roll apparatus is located between a setting zone and a separation location where the glass ribbon is separated to form a glass sheet.

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.

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.

Abstract: Embodiments of glass forming apparatuses are disclosed herein. In one embodiment, a glass forming apparatus may include a forming body defining a draw plane extending from the forming body in a draw direction. An actively-cooled thermal sink may be positioned below the forming body in the draw direction and spaced apart from the draw plane. An infrared-transparent barrier may be positioned between the actively-cooled thermal sink and the draw plane. The infrared-transparent barrier may comprise an infrared-transparent wall positioned proximate the actively-cooled thermal sink or an infrared-transparent jacket positioned around the actively-cooled thermal sink.

Abstract: An apparatus for making a glass sheet including a forming apparatus, a transition member, and a heat transfer device. The forming apparatus forms a glass ribbon from a supply of molten glass. The transition member encloses the glass ribbon adjacent the forming apparatus, and defines an interior space through which the glass ribbon passes. The heat transfer device is disposed within the interior space, and comprises a tube and a fin. The tube defines an exterior surface and an interior passage. The fin projects from the exterior surface. With this construction, the heat transfer device functions to extract heat radiated by the glass ribbon while minimizing the formation of flow vortices.

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.
