Abstract
A cutting device for shear-cutting of fiber strands comprises at least two cutting units which are rotatably drivable about an axis of rotation and two counter cutting units which are rigidly mounted relative to a base frame. The cutting edges of the cutting units as well as the counter cutting edges of the counter cutting units are positionable relative to a common cutting plane independently of each other. The forces acting on the counter cutting edges are measured during a cutting process by means of corresponding measuring sensors, allowing the position of the counter cutting edges to be controlled by means of a control unit via electrically driven displacement devices.

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.
