Abstract (en)
[origin: WO2022235182A1] A refiner disc of a refiner (100) for refining of lignocellulosic material, said refiner disc (30) having an active surface (1; 1') comprising a pattern of bars (10) and grooves (20) disposed in a number of pattern areas (41; 41'), wherein said pattern areas (41; 41') are positioned side by side with each other to cover at least a part of the active surface (1; 1'). Each of said pattern areas (41; 41') has a length, l, extending between a first end (43a) and a second end (43b) of the pattern area (41; 41') and a width, w, extending between two side edges (45a, 45b) of the pattern area, wherein a distance between the two side edges (45a, 45b) is smallest in the first end (43a) of the pattern area (41; 41') and is increasing towards the second end (43b) of the pattern area. Each of said pattern areas (41; 41') is positioned on the active surface (1; 1') such that a centre line, c, of the pattern area (41; 41') is provided at an angle, p, to a radius, R, of the refiner disc (30), said angle, p, being between 10-60°.
