The invention relates to an apparatus (10) for draping knitted fiber fabrics during the production of curved profile structural parts of fiber composite material. The apparatus (10) comprises at least one mold (12) having a mold surface (14) which corresponds to at least one section of the desired profile geometry and curvature of the subsequent profiled structural part, furthermore at least one clamping device (20) for clamping in at least one layer (16, 18) of a knitted fiber fabric along a clamping line (22) in the prestressed state, and finally a movement device (24) for producing a relative movement between the mold (12) and the at least one clamped in layer (16, 18) of the knitted fiber fabric in such a way that the mold surface (14) of the mold (12) moves close to the knitting fiber layer (16, 18) in a direction perpendicular or at least approximately perpendicular to the clamping line (22) and, in the further course of the relative movement, pushes through the clamping line (22) to such an extent that the knitted fiber layer (16) completely covers the mold surface (14), wherein the clamping device (20) is equipped to load the layer (16) of the knitted fiber fabric during the entire draping operation with a tensile force acting along the clamping line (22).
