Abstract

La presente invención se refiere a un aparato mejorado para el doblado de hojas de vidrio a ángulos relativamente agudos, incluyendo una estructura, un molde de doblado de tipo contorno soportado en la estructura disponiendo de una superficie de conformación prácticamente continua y que se forma al margen de la hoja de vidrio que se pretende doblar, caracterizado por el hecho de disponer de un conductor eléctrico montado en la estructura e incluyendo contactos eléctricos colocados opuestamente que se encuentran espaciados de la superficie de conformación y que pueden acoplarse con las porciones de borde marginales opuestas a la hoja de vidrio soportada en el molde, un aislante que aisla los contactos de la superficie de conformación, y un acoplador para el acoplamiento de los conductores eléctricos con una fuente de energía eléctrica.
