Abstract
A guiding device for a device for producing fibre preforms by the TFP process, the guiding device guiding the fibre strand. The guiding device has an opening with a variable cross-section for leading through the fibre strand, wherein the guiding device is fitted in the region of a sewing head of the TFP process device. The width of the fibre strands to be laid and attached can be increased, for example in portions of the path curve with small radii of curvature, so that undesired local thickenings are avoided in these portions of the path curve. An open-loop and closed-loop control device undertakes the path control of the sewing head and the control of the variation of the cross-sectional geometry of the guiding device. Existing devices for producing fibre preforms for composite components by the TFP process can be retrofitted with the guiding device.
