Abstract
An arrangement for detection of the sharpness of chopper knives that can be moved relative to a shear bar includes a sensor that detects the effective cutting forces directly or indirectly and an evaluation arrangement connected to the sensor. The evaluation arrangement integrates the measured values of the sensor over time in order to generate information concerning the sharpness of the chopper knives.
