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.

Abstract: Disclosed is a device for producing a fiber preform with virtually any desired surface geometry by the TFP process, wherein a fiber strand can be laid by a guiding device in virtually any desired path curve on a backing layer and the fiber strand can be attached on the backing layer by at least one fixing thread by means of a sewing head. The backing layer can be positioned in an xy direction in relation to the guiding device and the sewing head, wherein the sewing head and/or the guiding device can be positioned in a z direction. As a result of the separation of the positioning capabilities of the backing layer (xy direction) and the guiding device, the sewing head and the lower thread guide (z direction), a relatively simple construction of the device is obtained. By means of the device according to the invention, it is possible, for example, to produce fiber preforms for dome-shaped composite components that are used inter alia as pressure bulkheads for cabins in aircraft with virtually optimum properties.

Abstract: The invention relates to a guiding device 1 for a device for producing fibre preforms by the TFP process for composite components by laying and attaching a fibre strand 3 on a backing layer with virtually any desired path curve, the guiding device 1 serving substantially for guiding the fibre strand 3. According to the invention, the guiding device 1 has a through-opening 2 with a variable cross-sectional geometry for leading through the fibre strand 3, wherein the guiding device 1 can be fitted in the region of a sewing head of the device for carrying out the TFP process.As a result of the variable cross-sectional geometry of the through-opening 2, the width of the fibre strands 3 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. Here, an open-loop and closed-loop control device preferably undertakes both the path control of a sewing head of a device that is used for the TFP process and the control of the variation of the cross-sectional geometry of the guiding device 1. By means of the guiding device 1 according to the invention, already known devices for producing fibre preforms for composite components by the TFP process can be retrofitted in a simple way.
