Abstract (en)
The blade unit includes at least two blades, which have a blade foot and a cover plate (6). The unit has a measurement on the contact surfaces (12, 16) which is such that the pre-stressing between the Z-form plates prevents vibration. The blade foot may be in the form of a hammer foot (20) and the blades may interact on their axis of rotation (7) in operation, to intensify the pre-stress effect.
