| 摘要 |
The invention concerns a method of producing a multi-layered flat fibrous structure (1) which comprises a wearing layer (2), a carrier layer (3) and optionally further layers (10, 11). According to the invention, the carrier layer (3) is first produced from a multi-layered non-woven fabric in a mechanical non-woven-formation device, the elements (4, 5, 6) forming the wearing layer (2) then being applied to the carrier layer (3). Before application, the distribution of the elements (4, 5, 6), which differ in terms of their geometrical shape, is standardized such that the wearing layer (2) is substantially repeat-free. The elements (4, 5, 6) forming the wearing layer (2) are then joined at least to the carrier layer (3). |
