Abstract: Device for producing a complex three-dimensionally molded fiber reinforced pre-mold from a two-dimensional planar fiber arrangement (1), comprises: a molding tool (2) with a mold contour, which depicts the complex-dimensional shape of the pre-mold; and an automated feasible handling device (3) for the fiber arrangement. The two-dimensional planar fiber arrangement is positionable over the mold contour of the mold by means of the handling device. The device comprises a bulk material (5) and a bulk material-supply device (4) with an outlet opening. Device for producing a complex three-dimensionally molded fiber reinforced pre-mold from a two-dimensional planar fiber arrangement, comprises: a molding tool (2) with a mold contour, which depicts the complex-dimensional shape of the pre-mold; and an automated feasible handling device (3) for the fiber arrangement. The two-dimensional planar fiber arrangement is positionable over the mold contour of the mold by means of the handling device. The device comprises a bulk material (5) and a bulk material-supply device (4) with an outlet opening, which is positionable over the two-dimensional planar fiber arrangement to its filling by a guide device controlling the supply device. The fiber arrangement arranged in the molding tool with the bulk material is continuously increasingly fillable starting from a lowest point of the mold contour. The device comprises a form flexible bulk material mat and a bulk material mat-supply device, which is positionable over the two-dimensional planar fiber arrangement by a guide device controlling the supply device. The supply device comprises a means for gripping the bulk material mat. An independent claim is also included for producing the complex three-dimensionally molded fiber reinforced pre-mold from the two-dimensional planar fiber arrangement using the device, comprising placing and positioning the fiber arrangement over the mold contour of the molding tool which depicts the complex three-dimensional shape by the handling device, positioning the supply device with the outlet opening over a lowest point of the mold contour above the fiber arrangement and supplying a first portion of the bulk material on the fiber arrangement, and positioning the supply device with the outlet opening over an additional continuously increasing point of the mold contour above the fiber arrangement and supplying additional portions of bulk material on the fiber arrangement for gradual molding of the two-dimensional planar fiber arrangement to the mold contour and obtaining the complex-shaped three-dimensionally pre-mold or placing and positioning the fiber arrangement over the mold contour of the molding tool which depicts the complex three-dimensional shape by the handling device, placing the flexible bulk material mat using the bulk material mat-supply device on the fiber arrangement, molding the two-dimensional planar fiber arrangement on the mold contour and obtaining the complex three-dimensional molded pre-mold.
