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.
