Abstract

MéTODO E APARELHO PARA AQUECIMENTO DE FOLHAS DE VIDRO Folhas de vidro (3) são aquecidas em um torno de temperar. O forno compreende rolos (2) para carregar e transportar as folhas de vidro (3). Durante o aquecimento, as folhas de vidro (3) são osciladas, isto é, elas são deslocadas para frente e para trás, por intermédio dos rolos (2). Os rolos (2) são controlados por um dispositivo de controle (6). O dispositivo de controle (6) é usado para configurar um primeiro ponto crítico de oscilação (t~ 1~) de modo a ocorrer mais de 20 segundo após um tempo inicial de aquecimento (t~ o~).
