Zusammenfassung:An extrusion die makes a structuring fabric which has structuring-beads resting on sublayer-beads. The extrusion die has a flat first surface and a flat second surface, the first and second surfaces contact each other along a contact line. The first and second surfaces are inclined with respect to each other. The first surface has a first nozzle of a pair of nozzles for extruding a sublayer-bead and the second surface has a second nozzle of the pair of nozzles for extruding a structuring-bead on top of the sublayer-bead. The first nozzle has a substantially rectangular shape and the second nozzle has a shape that resembles a square with all four side edges bulged inwardly. Both the first nozzle and the second nozzle are located in close proximity to the contact line. The first nozzle has a first symmetry axis that is perpendicular to the contact line.
