Abstract

Se determina la orientacion de la estructura fibrosa de mantas de lana mineral, y en particular de mantas de lana mineral crespada. Por lo menos una imagende un área definida de la manta de lana mineral es registrada en una cámara de video y el perfil de la densidad lumínica de dicha imagen es evaluada con laayuda de procesamiento de imagen digital. El contenido de fibra vertical y el grado de crespado son calculados a partir del perfil de densidad luminosa y sonrepresentados y evaluados numéricamente y/o gráficamente.The orientation of the fibrous structure of mineral wool blankets, and in particular of crested mineral wool blankets, is determined. At least one image of a defined area of the mineral wool blanket is recorded in a video camera and the profile of the light density of said image is evaluated with the help of digital image processing. The vertical fiber content and the degree of creping are calculated from the light density profile and are represented and evaluated numerically and / or graphically.
