Abstract

Un método para el doblado de hojas de vidrio, el cual comprende las etapas de doblado por gravedad de una hoja de vidrio a temperatura elevada sobre unmolde de doblado por gravedad en una zona de doblado por gravedad de un horno, doblado por presión de la hoja de vidrio doblada por gravedad para darle unaforma deseada con un molde superior a la vez que la hoja de vidrio es sostenida por el molde de doblado por gravedad como un molde inferior en una zona dedoblado por presión del horno y controlando la temperatura ambiente en la zona de doblado por presión a fin de controlar la relación de enfriamiento de lahoja de vidrio en la zona de doblado por presión. La invención provee además, un método para el doblado por presión de hojas de vidrio, el cual comprende unahoja de vidrio doblada inicialmente y llevada sobre un molde articulado de doblado por gravedad y doblado por presión de la hoja de vidrio para lograr unaforma doblada definitiva, mediante el uso de un molde superior dedoblado por presión, el cual es bajado hasta la superficie superior de la hoja de vidrio,teniendo el molde superior de doblado por presión un peso neto que oscila entre 50 y 150 kg.A method for bending glass sheets, which comprises the steps of gravity bending a glass sheet at elevated temperature on a gravity bending mold in a gravity bending zone of an oven, pressure bending of the sheet glass bent by gravity to give it a desired shape with an upper mold while the glass sheet is held by the gravity bending mold as a lower mold in a pressure bending zone of the oven and controlling the ambient temperature in the zone pressure bending to control the cooling ratio of the glass sheet in the pressure bending zone. The invention further provides a method for the pressure bending of glass sheets, which comprises a glass sheet initially bent and carried over an articulated mold for gravity bending and pressure bending of the glass sheet to achieve a definitive bent shape, By using an upper pressure bending mold, which is lowered to the upper surface of the glass sheet, the upper pressure bending mold having a net weight ranging from 50 to 150 kg.
