摘要

Draping and cutting a fiber semi-finished product (1) for producing a preform, comprises close contour nestling the fiber preform at an integrally formed lower tool, fixing the fiber semi-finished product by a clamping device, assembling an upper tool comprising tool segments, which are displaceable individually or in groups and adjustable with respect to an pitch angle individually or in groups, determining number and form of the tool segments, choosing pitch angle for each tool segment, and closing the upper tool. At least a part of the tool segment is fed sequentially under the pitch angle. Draping and cutting a fiber semi-finished product (1) for producing a preform, comprises close contour nestling the fiber preform at an integrally formed lower tool, fixing the fiber semi-finished product by a clamping device, assembling an upper tool comprising tool segments, which are displaceable individually or in groups and adjustable with respect to an pitch angle individually or in groups, determining number and form of the tool segments, choosing pitch angle for each tool segment, and closing the upper tool. At least a part of the tool segment is fed sequentially under the pitch angle. At least a part of the fiber semi-finished product is sequentially formed on region of the preform, which to be molded. The individual clamping elements of the clamping device are controlled so that a maximum installation of the fiber semi-finished product at the lower tool is locally obtained in a region of the fiber semi-finished product, which is to be molded.
