Abstract: A method for refining aqueous suspended cellulose fibers including the step of guiding the fibers in an aqueous suspension between refiner fillings. The refiner fillings are provided with refining strips and interposed grooves and are located either on a rotor or a stator. The refiner fillings are caused to be rotatably moved relative to each other and pressed against each other, thereby transmitting mechanical a refining action to the cellulose fibers. The refiner fillings include barriers in at least part of the grooves, the barriers closing the grooves at least partially.
