Abstract
ESTA INVENCION SE REFIERE A UN PROCESO PARA UNA CORRECCION FINA DEL PERFIL DE GROSOR DE UNA PORCION DE SOPLADO (10) EN LA PRODUCCION DE UNA PELICULA DE BURBUJA EN LA QUE SE HACE VARIAR EL FLUJO DE AIRE REFRIGERANTE (6) EN ZONAS INDIVIDUALES PERIFERICAS DE LA BURBUJA DE LA PELICULA. CONFORME A ESTA INVENCION, SE TOMA AL MENOS PARTE DEL AIRE REFRIGERANTE MEDIANTE UNA RANURA DE SALIDA (20) QUE SE DIVIDE EN SEGMENTOS INDIVIDUALES SUMINISTRADOS POR SEPARADO EN LA DIRECCION PERIFERICA DE LA PELICULA, Y EL SUMINISTRO DE AIRE REFRIGERANTE ADICIONAL (4) MEDIANTE LA RANURA DE SALIDA ES, POR EJEMPLO, CONTROLADO POR SEGMENTOS USANDO SOPLADORES RADIALES . DE ESTA FORMA, ES POSIBLE REGULAR DE FORMA EXACTA LA ACCION REFRIGERANTE , Y ASI EL GROSOR DE LA PELICULA EN LAS ZONAS PERIFERICAS INDIVIDUALES DE LA BURBUJA DE LA PELICULA.
