<p>A process for measuring the friction and the coefficient of friction of sheet-shaped materials (layer materials), especially paper. This process is characterized in that a test surface of the material and a counter-surface of a material, in relation to which it is desired to measure the friction, in said testing process are loaded with a normal (transverse) force which is applied against the test surface of the sheet-shaped material, the position of said normal force in the space being maintained essentially stationary in the testing process, and a friction force acting in the direction of the tested surface, and determining the combination of friction force acting in the direction of the test surface and normal force, which can be applied without mutual movement (sliding) or are required resp. for sliding movement between the test surface and the counter-surface, for determining a resting friction (static friction) and a sliding friction (kinetic friction) between the test surface and the counter-surface.</p> |
