Abstract

"PROCESSO E DISPOSITIVO DE ARQUEAMENTO DE VIDRAçA". A invenção se refere a um processo de arqueamento de vidraças (2) aquecidas em sua temperatura de amolecimento na posição horizontal que compreende as seguintes características, as vidraças (2) são aquecidas em sua temperatura de arqueamento em um forno, as vidraças (2) são trazidas entre um quadro de arqueamento cóncavo (4) do qual as superfícies de fabrico descrevem um contorno menor do que as dimensões das vidraças (2) e uma fórma superior convexa de superfície cheia (3), as vidraças (2) são pressionadas entre o quadro de arqueamento (4) e a fórma superior (3) de maneira a que as vidraças (2) tomem pelo menos em alguns lugares o contorno da fórma superior (3) (etapa de arqueamento por prensa 1), um quadro de arqueamento final em forma de anel (5), do qual as superfícies de fabrico correspondem à forma definitiva das vidraças (2), é trazido em contato com as zonas marginais proeminentes das vidraças (2) e as vidraças (2) são pressionadas contra a fórma superior (3) (etapa de arqueamento por prensa 2), as vidraças (2) cujo arqueamento está terminado são submetidas a um tratamento de resfriamento ou de têmpera.
