Abstract

"MéTODO PARA MEDIR A FLEXãO DE UM PAINEL DE VIDRO A SER ENVERGADO SOBRE UM MOLDE EM ANEL". A invenção refere-se a um método para medir a flexão de um painel de vidro enquanto se enverga o painel de vidro sobre um molde em anel (1) . A flexão é medida com uma câmara de matriz e os dados de medição são acoplados para controlar o progresso de um processo de envergamento, especialmente o aquecimento do vidro ou a interrupção de um processo de envergamento. O molde em anel pode estar munido de ponteiros fixos para facilitar a medição feita por uma câmara. Além disso, pelo menos um ponto sobre a superfície do vidro, especialmente entre os ponteiros, torna-se visível para a câmara.
