Abstract (en)
[origin: CN104911857A] A method for homogenizing the stitching pattern in a needled fleece (6) requires a detector (22) which is arranged between a first needling device (2) and a second needling device (4) and detects areas in the fleece (6) where stitches are absent. Then the fleece (6) needled by the first needling device (2) is also needled in the second needling device (4), wherein at least one operating parameter or at least one structure parameter of the second needling device (4) is adapted specifically on the basis of the result of the detection of the absent-stitch areas, so that, during the further needling of the fleece (6) in the second needle machine (4), the absent-stitch areas are filled in a targeted manner.
