ABSTRACT:
A refining segment for a disc refiner for defibering and processing lignocellulose-containing fiber material. The refining segment has the shape of a circle sector and a refining surface with bars and intermediate grooves, which extend across substantially the entire refining surface. The bars are oblique in relation to the radius of the refining segment, and the angle of the bars in relation to said radius is greatest closest to the center and thereafter decreases in radial outward direction. The angle closest to the center shall be in the interval 20.degree.-45.degree. and farthest out in the interval -10.degree. to +20.degree..
