Abstract

En fremgangsmåte for bestemmelse av orienteringen av fiberstrukturen i en mineralull- matte og særlig i en kreppet mineralullmatte, omfatter på et videokamera å registrere minst et bilde av en mineralullmatte i en på forhånd bestemt sone og å evaluere billedet luminøse densitetsprofil ved bruk av digital billedbehandling. Andelen vertikale fibre og kreppefmheten beregnet fra den luminøse densitetsprofil og vises og evalueres digitalt og/eller grafisk.One method for determining the orientation of the fiber structure of a mineral wool mat and in particular in a creped mineral wool mat comprises on a video camera recording at least one image of a mineral wool mat in a predetermined zone and evaluating the image luminous density profile using digital imaging. The proportion of vertical fibers and the creepiness calculated from the luminous density profile is displayed and evaluated digitally and / or graphically.
