Active edge roll control in a glass drawing process

An apparatus for drawing a glass ribbon including an edge roll assembly that contacts the glass ribbon with a force that is dynamically altered by an actuator electrically coupled to a sensor that measures the force applied against the ribbon. Dynamic, or real-time, variation of the edge roll force...

More Information
Summary:An apparatus for drawing a glass ribbon including an edge roll assembly that contacts the glass ribbon with a force that is dynamically altered by an actuator electrically coupled to a sensor that measures the force applied against the ribbon. Dynamic, or real-time, variation of the edge roll force minimizes stress variability in the glass ribbon and improves ribbon shape control.
