The hub (1) supports two parallel discs (5) which are arranged in front of each other, have essentially the same diameter and which are provided with through bolt holes. The blade mountings (12) are arranged between the discs (5). The discs (5) are attached to the blade mountings (12) and pressed against these by means of bolts (17, 18), which extend through bolt holes (10, 11) in the respective discs (5).</p> |
