Abstract

"APARELHO PARA CURVAR UMA FOLHA DE VIDRO E ROLETE CURVO". Trata-se de uma folha de vidro 18 que é aquecida até uma temperatura de conformação em um forno de aquecimento 16, em que a folha de vidro aquecida é transportada ao longo de um plano de transporte definido por uma pluralidade de roletes de um transportador de roletes 13 e é movida para cima e para baixo sobre os roletes 12A a 12M, de acordo com a posição da folha de vidro 18, para curvar uma parte do plano de transporte com relação à direção de transporte da folha de vidro para curvar a folha de vidro 18 para ter uma curvatura desejada por seu próprio peso. Os roletes 12A a 12M são roletes curvados.
