Abstract: Systems, apparatuses and methods for processing a glass ribbon. A glass ribbon is supplied to an upstream side of a conveying apparatus comprising a conveyor device and a pulling device. The conveyor device establishes a primary plane of travel from the upstream side to a downstream side. The pulling device is located at the downstream side and applies a pulling force on the glass ribbon to convey the glass ribbon along a travel path that includes first, second and third bends, and into the primary plane of travel from a location downstream of the third bend and to the pulling device. At least one of the first, second, and third bends imparts a stress into a surface of the glass ribbon to flatten the glass ribbon. A viscosity of the glass ribbon at the third bend is greater than a viscosity of the glass ribbon at the first bend.

Abstract: A method of manufacturing a glass ribbon can comprise flowing a glass-forming ribbon along a travel path. The glass-forming ribbon can comprise a first major surface and a second major surface opposite the first major surface. A thickness can be defined between the first major surface and the second major surface. The method can comprise heating the first major surface of the glass-forming ribbon at a target location of the travel path while the glass-forming ribbon is travelling along the travel path. The heating can increase a temperature of the glass-forming ribbon at the target location to a heating depth of about 250 micrometers or less from the first major surface. The method can comprise cooling the glass-forming ribbon into the glass ribbon. Prior to the heating, the glass-forming ribbon at the target location can comprise an average viscosity in a range from about 1,000 Pascal-seconds to about 1011 Pascal-seconds.

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.

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 the first pull roll apparatus rotates with a substantially constant torque the second pull roll apparatus rotates with a substantially constant angular velocity. The control device is further configured to adjust the substantially constant torque of the first pull roll apparatus based on an operating condition of at least one of the first pull roll apparatus and the second pull roll apparatus. In further examples, methods of manufacturing a glass ribbon are provided.

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.
