Abstract
La presente invención se refiere a mejoras en aparato para doblar a presión una lámina de vidrio caliente, caracterizadas porque comprende: primer molde para doblar que tiene una superficie de configuración la cual incluye una primera parte y una segunda parte que tiene una curvatura más pronunciada que la primera parte; primera cámara de vacío para aplicar vacío en la superficie de configuración y soportar en ella la lámina durante la dobladura; segunda cámara de vacío para aplicar un vacío más intenso en la superficie de configuración en la primera parte junto a la segunda parte; segundo molde para doblar que tiene una superficie circunferencial de configuración complementaria con la de la superficie de configuración; un accionador para producir movimiento selectivo entre el primer y el segundo moldes para doblar a presión la lámina de vidrio con lo cual, la segunda cámara de vacío mantiene el contacto de la lámina de vidrio en la superficie de configuración en la primera parte junto a la segunda parte cuando se dobla la lámina a presión para evitar la curvatura negativa en la lámina de vidrio ya doblada.
