The invention relates to a method for producing a multiaxial structure out of multifilament threads which are superimposed with different orientations. The threads of the 0° position run in a direction of production and are inserted between the remaining multifilament layers superimposed with different orientations. In addition, the threads of the 0° position are guided in the area located in front of the stitch bonding machine by auxiliary means which ensure the correct superimposition or distribution thereof.

1. A method for producing a multiaxial structure out of multifilament threads that are superimposed in different orientations comprising the steps of: placing at least one multifilament thread layer; placing at least one 0° layer, wherein the 0° layer comprises multifilament threads at 0° to the production direction in between the at least one multifilament thread layer, wherein the at least one multifilament thread layer has a different orientation than the 0° layer; and guiding the 0° layer and the at least one multifilament thread layer having a different orientation in front of a stitch knitting machine through use of position securing means, distribution securing means, or a combination thereof, wherein the multiaxial structure need only be stitched once. 2. A method for producing a multiaxial structure out of multifilament threads that are superimposed in different orientations comprising the steps of: placing at least one multifilament thread layer; placing at least one 0° layer, wherein the 0° layer comprises multifilament threads at 0° to the production direction in between the at least one multifilament thread layer, wherein the at least one multifilament thread layer has a different orientation than the 0° layer; guiding the 0° layer in front of a stitch knitting machine through use of position securing means, distribution securing means, or a combination thereof; and fixing the orientations of the 0° layer in an introduction region, before feeding the multifilament threads of the multiaxial structure to a stitch-knitting machine, wherein the stitch-knitting machine knits the multiaxial structure together, using free-floating reeds. 3. A method for producing a multiaxial structure out of multifilament threads that are superimposed in different orientations comprising the steps of: placing at least one multifilament thread layer; placing at least one 0° layer, wherein the 0° layer comprises multifilament threads at 0° to the production direction in between the at least one multifilament thread layer, wherein the at least one multifilament thread layer has a different orientation than the 0° layer; guiding the 0° layer in front of a stitch knitting machine through use of position securing means, distribution securing means, or a combination thereof; and placing the multiaxial structure onto a conveying means running in the production direction, wherein the conveying means is equipped with a multiplicity of thin needles that secure, the distribution of all the layers of the multiaxial structure when they are placed onto the conveying means, and wherein the multiplicity of needles secure the 0° layer before the multifilament threads of the multiaxial structure are fed to the stitch-knitting machine to stitch the structure together. 4. The method according to claim 3, wherein the conveying means comprises a circulating conveyer belt. 5. The method according to claim 3, wherein the conveying means comprises an endless feed lattice. 6. The method according to claim 3, wherein the conveying means comprises a fabric belt. 7. The method according to claim 3, wherein all of the multifilament threads of the axial structure, are laid down upon a plane surface that is subjected to an underpressure. 8. The method according to claim 1, wherein at least the multifilament threads of the 0° layer are secured in the position, distribution, or a combination thereof in a material-interlocking manner with themselves or with at least one of the multifilament-thread layers aligned in different orientations.
