The invention relates to a method and to a device for producing a three-dimensional preform (6) in the course of the production of fiber-reinforced molded parts, wherein the method is performed using a draping device (2), which at least comprises a draping mold (5) for a woven fabric layer (3) and draping stamps (4, 4') having contact surfaces (12) for shaping the preform (6) from the woven fabric layer (3) by means of the draping device (2), which draping stamps can be moved relative to the draping mold (5), wherein the draping stamps (4, 4') form at least one clearance (8) with respect to each other. The aim of the invention is, among other things, to be able to produce three-dimensional preforms from in particular two-dimensional stacks of woven fiber fabric in better, repeatable quality. The proposed solution for a method is that at least one first and subsequently at least one second draping stamp (4, 4') are moved in the draping direction (9) in order to shape the woven fabric layer (3) at the contact surface (12), wherein with or without overlap with respect to at least one contact surface (12) of a draping stamp (4, 4'), the clearance (8) is bridged by means of at least one intermediate holder (7) that can be moved independently or by means of an intermediate holder that is operatively connected to at least one draping stamp (4, 4'). |
