Abstract

Se doblan por prensa y se templan hojas de vidrio, especialmente para su empleo en los cristales de vehiculos. Estos cristales requieren el doblado exactamente a una configuracion compleja, mientras cumplen con las normas elevadas de calidad optica y seguridad al fracturarse, con un costo aceptable. Se suministra un metodo para doblar y templar una hoja de vidrio (11), el cual comprende calentar esta hoja (11) en un horno (12), que incluye calentar cuando menos una porcion de la hoja a una temperatura mayor que otra porcion de la misma, transporta la hoja fuera del horno y dentro de una estacion (13) de doblado por prensa, configurar la hoja prensandola entre elementos de prensa, superior e inferior, complementarios, opuestos (61, 62), al menos uno de estos elementos se calienta internamente, transferir la hoja de vidrio doblada sobre un anillo portador (140) de lanzadera, que se conforma a la periferia de la hoja, y templar la hoja mientras esta soportada sobre el anillo portador. Tambien se describe un aparato correspondiente.
