- Figure 1 b shows a profile 4, the web 2 also has a flange 3 at its first end 2a and a foot 5 at its second end 2b.
- the profile 6 shown in FIG. 1c with the web 2 has two flanges 3, one of which protrudes vertically from one end 2a, 2b in the opposite direction in each case.
- the flanges 3 project away from the web 2 in the same direction as one another.
- FIG. 1e shows a profile 8 with only one foot 5.
- a coordinate system 9 is shown in FIG. 1, which defines the longitudinal direction 9a or z direction of the profile 1, its height or y direction 9b and its width or x direction 9c.
- the flanges 3 and feet 5 shown can protrude vertically or at an angle from the respective web 2.
- the three-dimensional shape of the end product or the preform from which the end product is produced determines the flat shape of the semi-finished product and the course of seams that fix the layers of the semi-finished product to one another at suitable locations.
- the products to be produced can also be curved, curved or rectilinear in their longitudinal direction.
- the preform is produced from at least two layers of tailored semi-finished textile products. These are placed in a fixing device (positioning device) 11, positioned and sewn in a fixing process in order to fix the at least two layers to one another in a region for subsequent draping steps (FIG.
- a foot 5 is formed by folding apart part of the sub-preform 20 along a longitudinal line (FIG. 7). After the preform has been formed from a sub-preform, insofar as the preform is not already the sub-preform, the preform is infiltrated with resin, for example in a corresponding mold, in order to form the plastic end product to be produced.
- the textile blanks or semi-finished products 10 comprise several layers of flat textile structures in the form of laid fabrics, embroidery or fabrics.
- the use of the corresponding semi-finished textile products 10 depends on their drapability, ie the deformability of the layers of the preform in the formation of distortions and curvatures thereon.
- the semi-finished textile must be capable of being shaped in such a way that in the end position there are no warps or folds in the material which negatively influence the mechanical properties.
- the semi-finished textile product 10 is first to be cut into a form from which a preform 20 and the plastic end product can be formed therefrom. This initial form preferably represents the developed area of the end product, taking into account the effects caused by the draping, e.g. B.
- Layers of a semi-finished textile product form the starting form, from which a preform 20 is formed by cutting and laying on top of one another, from which the preform suitable for producing the end product is produced, for example, by folding up areas of the same or areas of individual layers or by bending in the longitudinal direction.
- the semi-finished textile 10 is placed in a fixing device 11.
- the semi-finished textile 10 is preferably inserted such that a longitudinal side 12 extending in the longitudinal extent of the semi-finished product 10 bears against a reference or contact edge 15.
- the reference or contact edge 15 preferably runs in the longitudinal direction 9a of the semifinished product 10. However, several reference edges 15 can also be provided, for example if the textile semifinished product 10 has an irregularly running longitudinal side or edge 12.
- the clamping device 16 can also be designed differently than shown in FIG. 2. The fulfillment of a clamping function for an area is essential of the preform.
- the clamping device 16 can be detachably arranged on the fixing device 11.
- a clamping module 21 that can be used for subsequent steps can also be used.
- the layers of the semifinished product 10 within the sewing window 18 according to the prior art are sewn together with at least one seam 13 using a CNC-controlled lockstitch sewing machine.
- the clamping device 16 can also be used in the following steps. This is particularly appropriate when there is no flange to be formed on the preform.
- the clamping module 21 is used in the fixing device 11.
- the clamping module 16 has a clamping rail 21a running in the longitudinal direction 9a of the (sub-) preform 20, the longitudinal direction of which is designated by the reference number 22.
- the clamping rail 21a likewise has an abutment or reference edge 23 for forming a flange region 24, on which the corresponding side of the semifinished product 10, preferably its longitudinal side 12, is brought into abutment.
- the clamping rail 21a as a component of the clamping module 21 can have a plurality of holding devices 25 arranged along the longitudinal direction 22, which are preferably designed as clamping devices or clamping jaws 25, which are preferably arranged at a uniform distance from one another on a preferably flexible clamping rail or a spring steel band 26.

- These clamping devices 25 can have a front surface 27, which faces the web area 2, and a rear surface 28.
- both surfaces 27, 28 are moved relative to one another by a mechanism (not described in more detail).
- the clamping devices 25 have the function of holding the sub-preform or preform 20 in a desired position in relation to the contact edge 23.
- the clamping module 21 is provided to form a flange 3 at the end of the preform 20 fixed by the clamping jaws 25, in FIGS. 3a and 3b this is the end 1a as an example.
- the sub-preform or preform 20 is bent by a predetermined line in the longitudinal direction 22 by a predetermined angle, for example by 90 °, in order to form the preform or the (sub) preform 20 of the shape of the product to be produced, thus for example one of the shapes shown in FIGS. 1a to 1e.
- the crease or edge line 31 of the flange to be formed resulting from the edge depends on the shape of the clamping devices 25 transversely to the longitudinal direction 22. These extend to the edge line 31, so that the edge 30 by pressing the areas of the (sub) preform 20 abutting the clamping devices 25 against the e.g. perpendicularly adjoining surface of the front surface 27 of the clamping device 25 is accomplished.
- the above-described formation of a flange on the preform is omitted if the product to be produced does not have a flange.

- the clamping module 21 is brought to bear in order to form a curvature extending in the longitudinal direction 22 on a contact surface of a molded element 41, which in this case can be formed as a molded sheet.
- the shaped sheet 41 has a contact surface 42 which, over its longitudinal direction 42a, has a curvature which corresponds to the predetermined curvature of the product to be produced (shown by way of example in FIG. 5a d).
- This step of applying an edge region of the preform to a contact surface of the shaped element can also take place if no flange is provided, but e.g. a foot on the edge area, which lies opposite the clamped area. This is particularly advantageous when a curvature in the longitudinal direction 22 is to be achieved.

- the curvature given by the arch 41 makes it necessary to drape the sub-preform 20 in the web area.
- the draped area is then e.g. To fix sewing.
- the preform 20 with the first 1 b and the second 1 b edge area is inserted into a sewing frame or sewing material holder 52 in order to fix the layers of the preform by sewing.

- a plurality of holding devices 54 arranged along the curvature are used to form the foot or to fix the web (see FIG. 6a).
- this is inserted with a clamping module 21 with the clamping rail 21a and the form sheet into a sewing frame 52 for forming and sewing preforms 20 curved in the longitudinal direction with a flange 3.
- the construction of the device depends on the accessibility of the sewing method to be used.
- Step 50 is then carried out as step 50a described below with reference to FIG. 6b.
