| 摘要 | The invention relates to a method and a device for producing a three-dimensional preform (19) from a laid scrim (1) in the course of the production of fiber-reinforced molded parts, comprising a draping device (3) and a transport device (21) for the laid scrim (1), the draping device (3) comprising at least one draping mold (18) for a laid scrim (3) and means for shaping the laid scrim (3) in accordance with the contour of the draping mold (18), the means being movable relative to the draping mold (18). The aim of the invention is to ensure an expeditious and yet high-quality shaping, especially of large-surface-area and/or complex geometries of a preform. At least a first and a second tray (7) are used in the method as the transport device (21), the first tray (7) releasing the laid scrim (3) for fixation by means of a fixing ram (4) and/or a draping ram (5) and the second tray (7) then placing the laid scrim (1) in the draping mold (18) by way of a movement originating from the draping device. | ||||||
