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.

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 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.
