Abstract

The invention concerns a method for controlling the refining results imparted on stock in refiners used in the pulp and paper industry, said refiner performing refining between opposed refiner blades (1), of which at least one is rotary, and said blades having protruding blade edges (2, 3) on their surface. The method according to the invention is implemented by arranging the cutting length of the refiner blades (1) to be alterable by moving one or a multitude of the blade edges (3) with respect to the other blade edges (2). <IMAGE>
