ABSTRACT:
The invention discloses an impact shears having a rotor with individual chopping blades disposed on the rotor in a predetermined arrangement and with blade(s) or blade system that is generally stationary vis-à-vis the rotation of the rotor. The blade is held in a blade holder on the stator side of the rotor. The blade holder is movable on the stator about an axis parallel to the rotational axis of the rotor and carries at least two blades, or blade systems, that are expediently disposed at the same angular distance to one another. The blade holder can be rotated about an axis that extends parallel to the rotational axis of the rotor so that every blade of the blade holder can be brought in a cutting position to interact with the chopping blades of the rotor and can be locked in position with respect to the chopping blades.
