Abstract

Procédé d’identification d’orientation de bande, la bande (50) comprenant une première portion (I) et une seconde portion (II) différentes l’une de l’autre, la première portion (I) et la seconde portion (II) étant disposées côte-à-côte selon la direction de largeur (La) et reliées continument l’une à l’autre via une portion de jonction (III) selon la direction de longueur (Lo), dans lequel : -on scanne une face (50A, 50B) de la bande (50) s’étendant selon les directions de largeur (La) et de longueur (Lo) à l’aide d’un profilomètre (20A), -on génère, à partir de données issues du profilomètre (20A) pendant l’étape de scan, une image représentative de la réflectance de la face (50A, 50B) scannée de la bande (50), et -on identifie la position relative de la première portion (I) et de la seconde portion (II) selon la direction de largeur (La) à partir de l’image représentative de la réflectance.
