Abstract

L'invention porte sur un ruban utilisé pour effectuer une mesure directe du diamètre ou de la circonférence d'un objet. Ce ruban est constitué d'une bande de matériau d'une largeur (W) donnée et d'une épaisseur (t) donnée et se caractérise en ce que la bande de matériau comporte sur sa surface des graduations dans une unité de longueur comprenant un point zéro et une graduation principale qui vient en contact avec le point zéro lorsque la bande de matériau est enroulée en un seul tour de spirale autour de l'objet à mesurer et qui correspond au diamètre ou à la circonférence de l'objet à mesurer. Du fait que le ruban peut être formé dans une bande de matériau d'une longueur et d'une épaisseur données, les coûts du matériau et les coûts de traitement sont considérablement réduits.
