Patent ID: 8438959

Claim:
A cutting device for shear-cutting of fibre strands comprising a base frame; at least two cutting units; which comprise in each case a blade with a cutting edge, with a first cutting edge defining a cutting plane; and a second cutting edge being displaceable and positionable in the cutting plane independently of the first cutting edge; which are arranged at a cutting spindle mounted to the base frame, the cutting spindle being rotatably drivable about an axis of rotation which is perpendicular to the cutting plane; at least two counter cutting units; which comprise in each case a counter blade with a counter cutting edge, with the counter cutting edges being displaceable and positionable in the cutting plane independently of each other by means of a respective electrically driven displacement device; and a force acting on the respective counter cutting edge being detectable as a measuring signal by means of a respective measuring sensor; and which are rigidly arranged at the base frame about the axis of rotation; at least two fibre supply units for supplying fibre strands between the at least two cutting edges and the respectively associated counter cutting edges; and a control unit which is configured in such a way that depending on the associated measuring signal, each of the counter cutting edges is displaceable relative to the cutting plane by means of the respective electrically driven displacement device.
