Abstract

''PROCESSO DE RECURVAMENTO E DE TêMPERA DE UM VIDRO E QUADRO DE CONFORMAçãO PARA A EXECUçãO DO DITO PROCESSO''. No decorrer de um processo de recurvamento e de têmpera de um vidro, o vidro é recurvado na forma desejada, com o auxílio de um quadro de conformação (1). Por meio desse mesmo quadro de conformação (1), a superfície inteira dos dois lados do vidro recurvado é em seguida resfriada bruscamente em um posto de têmpera que segue o posto de recurvamento por insuflação de ar frio com o auxílio de caixões de insuflação munidos de bicos insufladores. Durante o resfriamento brusco da totalidade da superfície, as zonas de bordas do vidro que repousam sobre o quadro de conformação (1) são submetidas a uma projeção de ar frio suplementar pela admissão adequada de ar comprimido nas aberturas (4) que atravessam o quadro de conformação (1).
