Abstract
The invention relates to a method for determining the radial modulus of elasticity of paper or a corresponding web-like material that is 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 necessary in the determination of the radial modulus of elasticity are conducted in a production machine for paper or a corresponding material.
Claims5
