Abstract

Apparatus for producing glass ribbon includes a control device configured at least periodic thermal stress compensation of the glass ribbon by independently adjusting operation of a plurality of temperature adjustment elements based on stress characteristic information at least periodically obtained from a stress sensor apparatus. In further examples, methods of producing glass include at least periodically sensing a stress characteristic of a glass ribbon and at least periodically changing a transverse temperature profile of the glass ribbon based stress characteristic information. In further examples, methods include the step of changing a transverse temperature profile of the glass ribbon only if a measured parameter is within an operating range associated with the parameter.
