Abstract

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. A belt tray (8) is used in the method as the transport device (21), said belt tray (8) draping the laid scrim (1) in a targeted manner onto the draping mold (18) by way of a movement of its belt (9) and a corresponding superimposed relative movement of the belt tray (8) itself.
