Abstract

The invention relates to a device for setting the cutting gap between a rotor, having cutting blades and rotatable about its rotor axis, and a counter-blade body, which carries a cutting edge, can be fixed in position and can be set relative to the cutting blades of the rotor for optimizing the gap by an adjusting mechanism acting perpendicularly to the rotor axis, the adjusting mechanism having a slide guided in a linear guide, and the linear guide being arranged at an angle deviating slightly from the parallelism to the rotor axis, and the counter-blade body being arranged on the slide in such a way that the parallelism of cutting edge and cutting blade is ensured, or a U-shaped counter-blade body being provided, the legs of which are pressed apart elastically by pressure elements for setting the cutting gap. Furthermore, the invention relates to a method of setting the cutting gap between a rotor and a fixed cutting edge.
