A refining surface (1, 2) of a refiner for defibrating lignocellulose-containing material has a feed edge (14) and a discharge edge (15) and has a first blade groove (17a) and a second blade groove (17b), with a blade bar (16) therebetween. A distance (D, D17a, D17b) of the bottom (18) of the first blade groove (17a) and the second blade groove (17b) from an upper surface (16a) of the blade bar (16) is arranged, at least in a part, to change substantially continuously in a direction of travel (A) of the blade grooves. The distance of the bottom of the second blade groove from the upper surface of the blade bar deviates from the distance of the bottom of the first blade groove from the upper surface of the blade bar at substantially the same distance (SD) from the feed edge of the refining surface. |
