Abstract: A cutting unit includes a blade for cutting at least one fiber, particularly on a cutting support, and particularly for producing fiber preforms which are, in particular, a precursor in the production of fiber-reinforced plastic components. A guide device is arranged so as to guide at least one of either the blade or a cutting support which can be moved relative to the blade, along a linear path in order for cutting to take place. At least one such cutting unit is preferably used in a device for producing fiber preforms which are, in particular, a precursor in the production of fiber-reinforced plastic components. The device has at least one unwinding station for providing at least one fiber, and at least one gripper which can grip individual or a plurality of fibers at their front ends.

Abstract: A device and corresponding method for producing three-dimensional components from impregnated fiber tapes. The device includes a plurality of grippers, arranged alongside one another, for gripping fiber tapes impregnated with matrix material, the grippers can be displaced in a linear manner on mutually parallel paths between a pick-up position and a maximum position such that the fiber tapes can be tensioned between the grippers and respectively associated transfer devices; a rotatable table on which the fiber tapes can be laid in a first and at least one additional layer; a severing device which can sever the fiber tapes close to the transfer device; a heating device for heating the layers to 160° C. to 400° C.; a first molding tool and one or more additional molding tools which can be moved together to three-dimensionally form the layers; and a transporting device which can transport the heated layers between the molding tools.
