Abstract
LA PRESENTE INVENCION SE REFIERE A UN ANILLO DE CURVATURA POR PRESION HEMBRA (50) PARA UTILIZARLO AL CURVAR POR PRESION HOJAS DE VIDRIO FUERA DE UN HORNO Y DE MANEA MAS PARTICULAR A UN ANILLO DE CURVATURA POR PRESION HEMBRA QUE SE CALIENTE DE MANERA ADECUADA CON UNOS ELEMENTOS CALENTADORES (69) DURANTE EL CICLO DE CURVATURA PARA REGULAR LA TRANSFERENCIA DE CALOR ENTRE EL MARGEN PERIFERICO DEL VIDRIO Y EL ANILLO DE CURVATURA HEMBRA CON EL QUE SE ENCUENTRA EN CONTACTO. AL HACER ESTO, LA TENSION EN EL BORDE ANTERIOR Y LOS ESFUERZOS LONGITUDINALES SE REDUCEN DE MANERA CONSIDERABLE CON LO QUE SE REDUCE LA FORMACION DE GRIETAS AL ENFRIARSE Y LA ROTURA DEL VIDRIO DURANTE Y DESPUES DE LA PRODUCCION. EL ANILLO HEMBRA SE PUEDE CUBRIR CON UNA CAPA (78) DE UN TEJIDO DE FIBRAS DE VIDRIO O SIMILAR PARA QUE TENGA UNA LIGERA FLEXIBILIDAD PARA ENGANCHAR A LA HOJA DE VIDRIO.
