ABSTRACT:
A glass treating apparatus suitable for heating glass sheets, such as in a process of forming motor vehicle windshields, comprises a heater suppoted by a modular support structure. The heater comprises a non-monoplanar heating surface subdivided into heating zones. The heating zones are individually controlled. The heating surface can approximate the configuration of the glass sheet. The invention allows preferential heating of selected zones of the glass sheet. One or more such modular radiant heater assemblies can be used in a glass forming process.
