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: Methods provide for post processing at least one flexible glass sheet with the step of providing the glass sheet with an initial shape. The method then further includes the step of flexing the glass sheet into a secondary shape from the initial shape. The method then further includes the step of post processing the glass sheet while biasing the glass sheet into the secondary shape. The method then still further includes the step of releasing the glass sheet to at least partially return to the initial shape.

Abstract: A method for forming a glass sheet includes forming a glass ribbon. A robot arm is operated to move an end effector through a preprogrammed cycle. The cycle includes engaging a segment of the glass ribbon with the end effector, separating the engaged segment from the glass ribbon to generate a glass sheet, and moving the glass sheet away from the glass ribbon. The preprogrammed cycle designates predetermined positions of the end effector at predetermined points in time. While the robot arm is operating through the preprogrammed cycle, a parameter indicative of a force being exerted on the glass ribbon by the end effector is sensed. A position of the end effector is altered to differ from the predetermined position at the corresponding point in time when the sensed parameter deviates from a target value. An excessive force applied to the glass ribbon can be reduced in real-time.

Abstract: A glass manufacturing apparatus includes a forming apparatus defining a travel path extending in a travel direction. The forming apparatus conveys a ribbon of glass-forming material along the travel path in the travel direction of the forming apparatus. The glass manufacturing apparatus includes a cooling tube extending substantially parallel to the travel path and extending across the travel direction. The cooling tube includes a plurality of orifices spaced apart along the cooling tube and facing the travel path. Methods of manufacturing glass can comprise flowing a coolant from an outlet of a conduit in a direction toward a target location of a flowing ribbon of molten material. Methods can also include changing a phase of the coolant while the coolant is flowing towards the target location. The change in phase can cool the target location.
