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.

Apparatus and method for rapid cooling of a glass ribbon in a glass making process

A method and apparatus for processing glass comprising a forming apparatus in a first processing zone, the forming apparatus configured to form a glass ribbon having a first direction of travel in the first processing zone. The apparatus also includes a first cutting apparatus in a second processing zone, the first cutting apparatus configured to separate one or more portions of the glass ribbon, the glass ribbon having a second direction of travel. The apparatus includes a first buffer zone between the first processing zone and the second processing zone in which the glass ribbon is supported in a first catenary between two, spaced-apart payoff positions. The second direction of travel in the second processing zone can be orthogonal to the first direction of travel in the first processing zone.

Methods and systems for processing of glass ribbon

A method of continuously processing glass ribbon having a thickness &#x2264;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.

Continuous processing of flexible glass ribbon

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.

Glass manufacturing apparatus and methods

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.

Methods for producing a glass ribbon

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, a second pull roll apparatus, and a third pull roll apparatus such that at least one of a first upstream pair of draw rolls rotates with a substantially constant torque, at least one of a first midstream 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.

Methods and apparatuses for fabricating continuous glass ribbons are disclosed. The method includes forming the continuous glass ribbon by drawing the continuous glass ribbon from a draw housing in a drawing direction, heating at least one portion of a central region of the continuous glass ribbon at a heating location downstream of the draw housing, sensing a temperature of the continuous glass ribbon at a sensed temperature location downstream of the draw housing, and automatically controlling the heating of the at least one portion of the central region of the continuous glass ribbon based on the sensed temperature to mitigate distortion of the continuous glass ribbon.

Methods and apparatuses for fabricating continuous glass ribbons

Roller pairs and draw apparatus for processing glass ribbons are disclosed. The roller pairs applying force to a glass ribbon moving through the draw apparatus. The roller pairs include a first roller assembly and a second roller assembly positioned along opposite sides of the glass ribbon. A shaft of the second roller assembly is coupled to an actuation system that includes a repositionable support member allowing translation of the shaft of the second roller assembly in a direction transverse to the draw direction of the glass ribbon, a pneumatic actuator controlling a position of the contact wheel of the second roller assembly in the direction transverse to the draw direction of the glass ribbon, and a pneumatic reservoir in fluid communication with the pneumatic actuator delivering fluid at an elevated pressure to the pneumatic actuator.
