The blades are rotationally symmetric about a rotational axis (4), and the cover plates have side surfaces (5, 6) aligned parallely in a circumferential direction (3) and two front open areas (7, 8) between which a front contact surface (10) is arranged. A blade base is formed rhomboid-shape or parallelogram-shape perpendicular to the rotational axis. The front contact surface has same length as another front contact surface (11) of the cover plates.
