Abstract: A device for producing textile planar structures formed of a plurality of portions deposited beside one another of fiber rovings. A supply device provides a fiber rovings at a transfer installation. A plurality of path guiding rails are disposed beside one another and above the depositing face. A gripper unit and a cutting unit are disposed on each path guiding rail. Each gripper unit and each cutting unit is movable and positionable along the path guiding rail independently of the gripper units and cutting units of the other path guiding rails. The gripper units grab the fiber roving from the transfer installation and move their free end to a desired terminal position. The cutting units severs the rovings at a cutting position. The gripper units and the cutting units have a downholder for pressing the fiber roving against the depositing face.

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.
