Abstract (en)
[origin: EP1424421A1] The melt-spun filaments are deposited in two or more layers. Guide sheets control the angle of filament deposition. They are placed essentially parallel in a first layer. A second layer is laid in the same manner, but in mirror-reversal. An Independent claim is included for the geotextile so prepared.
