Abstract

"Procedimiento y dispositivo de curvado de hojas de vidrio", principalmente hojas de vidrio llevadas a temperatura de reblandecimiento, sobre un lecho de conformación constituido por una serie de varillas conformadoras, caracterizados porque el lecho de conformación comprende una porción de perfil curvilíneo en la dirección longitudinal, tangente a los medios de traída de las hojas situadas inmediatamente por encima, realizando con dichos medios altos una trayectoria de radio de curvatura continuamente variable.
