Abstract

RESUMEN La invención se relaciona con un método para doblar cristales, que comprende los siguientes pasos: proporcionar un cristal calentado a la temperatura de doblez, asegurar el cristal contra una superficie de contacto de un primer molde de doblez, prensar el cristal entre el primer molde de doblez y un marco de prensa, donde la superficie de contacto tiene una sección superficial externa que es adecuada para un doblez final de borde en una región de borde del cristal, donde el marco de prensa tiene una superficie de prensado que es complementaria a la sección superficial externa del primer molde de doblez, transportar el cristal sobre el marco de prensa a un segundo molde de doblez, donde el predoblez de superficie ocurre en una región interna del cristal rodeada por la región de borde y por medio de la gravedad durante el transporte, prensar el cristal entre el segundo molde de doblez y el marco de prensa, donde el segundo molde de doblez tiene una superficie de contacto con una sección superficial externa que es adecuada para el doblez final de borde en la región de borde del cristal, donde la superficie de prensado del marco de prensa es complementaria a la sección superficial externa del segundo molde de doblez, asegurar el cristal contra la superficie de contacto del segundo molde de doblez, donde el predoblez de superficie ocurre en la región interna del cristal, transportar el cristal sobre un marco de templado a un dispositivo de enfriamiento para el templado térmico del cristal, donde durante el transporte, el doblez final de superficie ocurre en la región interna del cristal por medio de la gravedad.
