Abstract
The invention relates to a device for protecting selective cutting machines against overload, in which the selective cutting machine has cutting tools, in particular cutting rollers, rotatably supported on a pivotable cantilevered arm, and both the cutting tools and the cutting arm are connected to separate drive mechanisms. At least one strain or deformation measuring sensor is disposed on the pivotable cantilevered arm, and its signals are delivered to an evaluation circuit; the evaluation circuit is connected via control lines at least to the drive mechanisms of the cutting arm and the cutting tool.
