Abstract

métodos para modelar uma folha de vidro são descritos compreendendo as etapas (i) prover um suporte de modelagem para suportar a folha de vidro; (ii) aquecer a folha de vidro a uma temperatura para modelagem; (iii) posicionar a folha de vidro no suporte de modelagem; e (iv) modelar a folha de vidro no suporte de modelagem, em que, durante a etapa (iv) pelo menos uma porção da folha de vidro é deliberadamente resfriada. em modalidades preferidas, a etapa de modelagem (iv) compreende dobrar em prensa a folha de vidro amolecida por calor entre um suporte de modelagem inferior e um membro de modelagem superior, em que, durante a etapa (iv) apenas uma porção da superfície principal da folha de vidro voltada para o suporte de modelagem inferior é resfriada direcionando um ou mais jatos de ar para a dita porção. a folha de vidro modelada encontra uso particular em um vidro laminado. aparelho útil na realização do método para modelar é também descrito.
