Abstract

EL INVENTO SE REFIERE A UN PROCEDIMIENTO DE OBTENCION DE CRISTALES ABOMBADOS Y/O ESMALTADOS SEGUN EL CUAL LAS LAMINAS DE VIDRIO SE CARGAN DE FORMA PLANA UNA A UNA EN HORNO DE CALENTAMIENTO QUE ATRAVIESAN TRANSPORTADAS, POR EJEMPLO, POR UN LECHO DE RODILLOS (1) ESTAS SON LLEVADAS A UNA ESTACIOM DE ABOMBAMIENTO MONTADA EN EL EXTREMO DEL HORNO DE CALENTAMIENTO, CONSTITUIDA POR UN RECINTO CERRADO, EVENTUALMENTE AISLADO TERMICALMENTE, Y SON CONDUCIDAS A UNA ESTACION DE ENFRIAMIENTO, EN ESPECIAL DE TEMPLE TERMICO, SIENDO DICHAS LAMINAS DE VIDRIO POSICIONADAS EN LA ESTACION DE BOMBEO POR DEBAJO DE UN ELEMENTO SUPERIOR (2,2''), SON RETIRADAS Y PLAQUEADAS CONTRA DICHO ELEMENTO SUPERIOR (2,2'') Y DESPUES DIRIGIDAS HACIA UNA ESTACION DE ENFRIAMIENTO, DESPUES SE DIRIGE INSUFLACION DE AIRE CALIENTE HACIA EL ELEMENTO SUPERIOR (2,2''), ENTRE DOS TRATAMIENTOS SUCESIVOS.
