Abstract
In a method for determining the radial modulus of elasticity of paper or a corresponding web-like material that can be reeled or wound on a reel, 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 of paper or corresponding material outside the reeling or winding position by loading the reel with a press member.

A method for determining a radial modulus of elasticity of a paper web or a corresponding web-like material, which can be reeled or wound on a reel, in which method the connection between the force and deflection of a web material arranged in layers is measured, wherein the method comprises the steps of:
- reeling or winding the web material to form a reel in a reeling or winding position, the reel defining a reel axis and a radial direction toward the reel axis;
- transferring the reel from the reeling or winding position to a measurement position;
- and
- making measurements of force and deflection so as to allow calculating the radial modulus of elasticity of the reel of the web material in the measurement position outside the reeling or winding position.
