Abstract

LA INVENCION CONCIERNE A UN PROCESO Y UN DISPOSITIVO DE CURVATURA DE UNA HOJA DE VIDRIO (4) UTILIZANDO UN ELEMENTO SUPERIOR (2) DEL QUE LA CARA (5) VUELTA HACIA EL TRANSPORTADOR (1) TIENE DIMENSIONES INFERIORES A LAS DE LA HOJA DE VIDRIO (4) ESTA LEVANTADA POR DEBAJO DE ESTE TRANSPORTADOR (1) Y APLICADA CONTRA DICHO ELEMENTO SUPERIOR (5) POR DOS FUERZAS DE NATURALEZA NEUMATICA. SEGUN LA INVENCION SE APLICA A LAS PARTES DE LA HOJA DE VIDRIO QUE DESBORDA EL ELEMENTO SUPERIOR CONTRA UN AMORTIGUADOR FLEXIBLE (8) DEL QUE LAS DIMENSIONES SON SUPERIORES A LAS DE LA HOJA DE VIDRIO (4) Y QUE ES TENSADO AL CONTACTO CON LA CARA DEL ELEMENTO SUPERIOR (2) VUELTO HACIA LA HOJA DE VIDRIO (4) Y AL EXTERIOR DEL ELEMENTO SUPERIOR EN LAS DIRECCIONES TANGENCIALES A LA SUPERFICIE DEL ELEMENTO SUPERIOR EN SUS ZONAS MARGINALES. LA INVENCION SE APLICA ESPECIALMENTE A LA PRODUCCION DE CRISTALES PARA AUTOMOVILES.
