Abstract
Un método para fabricar una película soplada (F) que comprende extrudirla a través de un troquel (D), aplanar la película con un ángulo de plegado que varía, medir un perfil transversal de una propiedad característica de la película soplada, propiedad que se suma sobre dos porciones yuxtapuestas de una pared de la película aplanada, y estimar un perfil polar con base en el perfil transversal, el método que comprende además determinar posiciones polares de la periferia de la película soplada aplanada que corresponden a una posición transversal de la película, determinar los valores angulares discretizados que flanquean cada una de las posiciones polares y, con base en los valores angulares discretizados, calcular los coeficientes de interpolación que asocian el perfil polar de la película con un perfil polar discretizado de la película y, con base en los coeficientes de interpolación, actualizar la estimación del perfil polar discretizado de la película aplicando un filtro de Kalman.
