Abstract
Procedimiento y dispositivo para el curvado de hojas de vidrio, con poco radio de curvatura, y en particular de hojas de vidrio que posean pliegues-marcados, caracterizados porque en una primera etapa se aprisiona la hoja de vidrio plana, colocada en posición vertical y puesta a temperatura de curvado, entre dos figuras de formación, constituida, cada una, de elementos articulados entre sí, colocados a todo lo largo; ciertas regiones de la hoja sufren entonces, llegado el caso, un ligero curvado, puesto que, en una segunda etapa, se curva la hoja de vidrio así mantenida.
