Abstract
L'invention concerne un procédé permettant de prévoir et/ou de commander les caractéristiques de résistance d'une matière de type film en liaison avec des équipements et des procédés de production de cette matière. Les mesures sont réalisées localement sur la matière de type film et avec une résolution spatiale élevée - de 20 mm maximum - pour obtenir une valeur moyenne et une variation concernant au moins une caractéristique mécanique locale de la matière de type film. La valeur de résistance ou le signal de commande calculés à partir des valeurs de mesure obtenues sont utilisés pour réaliser la prévision de résistance et/ou la commande du procédé et de la qualité souhaités.
