The invention relates to a method for determing the radial modulus of elasticity of paper or a corresponding web-like mateiral that can be reeled or wound on a reel. In the method the connection between the force and deflection of a material arranged in layers is measured. The measurements of force and deflection necessary for calculating the radial modulus of elasticity are performed on a reel (R) of paper or corresponding material outside the reeling or winding position by loading the reel with a press member (1).
L'invention concerne un procédé de détermination du module d'élasticité radial de papier ou d'un matériau en bande correspondant pouvant être enroulé ou bobiné sur une bobine. Ledit procédé consiste à mesurer le rapport entre la force et la déflexion d'un matériau disposé en couches. Les mesures de force et de déflexion nécessaires au calcul du module d'élasticité radial sont effectuées sur une bobine (R) de papier ou d'un matériau correspondant, en dehors de la position d'enroulement ou de bobinage, par chargement de la bobine au moyen d'un élément de compression.
