Abstract

_(UN METODO SUSTANCIALMENTE CONTINUO DE CONFORMAR UN ARTICULO IDONEO PARA UNA PREFORMA DE GUIA-ONDAS OPTICO, JUNTO CON UN APARATO CORRESPONDIENTE . EL PROCEDIMIENTO CONSISTE EN APLICAR UN MATERIAL SUBDIVIDIDO EN PARTICULAS A LA SUPERFICIE EXTERIOR DE UN MIEMBRO INICIADOR HASTA FORMAR UN RECUBRIMIENTO, SE TRASLADA LONGITUDINALMENTE AL TIEMPO QUE SE APLICAN CANTIDADES ADICIONALES DE DICHO MATERIAL, DE MODO QUE SE INICIA LA FORMACION DE UN CUERPO, EL CUAL SE CALIENTA HASTA CONSOLIDAR EL MATERIAL SUBDIVIDIDO. EL APARATO COMPRENDE UN MIEMBRO INICIADOR Y MEDIOS PARA APLICAR MATERIAL SUBDIVIDIDO EN PARTICULAS A LA SUPERFICIE EXTERIOR DE POR LO MENOS UNA PORCION DE DICHO CUERPO INICIADOR, HASTA FORMAR UN RECUBRIMIENTO SOBRE EL.
