Abstract: A device for manufacturing fibrous board has a board carrier and a plurality of at least four cutting tools for separating a fibrous material, in particular strand-shaped or tape-shaped fibrous material into portions, and for depositing the portions. The board carrier is displaceable below the depositing cutting tools here through in at least one movement direction. The depositing cutting tools are substantially stationary and are disposed beside one another in such a manner that the portions of these depositing cutting tools may be simultaneously deposited beside one another on the board carrier.

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: The invention relates to a method for depositing one- or two-dimensional fiber structures in order to form a two- or three-dimensional fiber structure, in particular a fiber structure in the form of a fiber-reinforced plastic (FRP) or FRP semi-finished product, using a production machine including at least one depositing device and at least one fiber support. The one- or two-dimensional fiber structures have at least one unidirectional fiber layer. The depositing device deposits the one- or two-dimensional fiber structures onto the fiber support in a depositing direction in a controlled manner such that the fiber directions of the deposited one- or two-dimensional fiber structures assume an angle ?>20°, preferably ?>60°, and a maximum of ?=90°, relative to the depositing direction. The one- or two-dimensional fiber structures are deposited on the fiber support in a substantially tension-free manner with respect to the fiber direction of the fiber structures.

Abstract: A method and a device separate a fibrous material into portions, and deposit the portions. The device has a separation roller with cutters which are disposed on the roller circumference of the separation roller, a counter roller, and a portion carrier. The separation roller and the counter roller are rotatable in opposite directions and are disposed such that the fibrous material is guided through between the separation roller and the counter roller and thereby may be severed by one of the cutters interacting with the counter roller. A plurality of integrated retaining elements are configured such that at least one of the retaining elements exerts a retaining force on a portion and are present on the counter roller or on the separation roller, by which the portion is retained on the roller and, after severing, may be moved by a distance conjointly with the roller circumference of this roller.
