EXTRUSION DIE FOR MAKING A STRUCTURING FABRIC

The invention concerns an extrusion die for making a structuring fabric having structuring-beads resting on sublayer-beads, the extrusion die comprising a substantially flat first surface and a substantially flat second surface, wherein the first surface and the second surface contact each other along a contact line and wherein the first surface and the second surface are inclined with respect to each other, wherein the first surface comprises a first nozzle of a pair of nozzles for extruding a sublayer-bead and wherein the second surface comprises a second nozzle of the pair of nozzles for extruding a structuring-bead on top of the sublayer-bead, wherein the first nozzle has a substantially rectangular shape and wherein the second nozzle has a shape that resembles a square with all four side edges bulged inwardly, wherein both, the first nozzle and the second nozzle are located in close proximity to the contact line, wherein the first nozzle has a first symmetry axis that is perpendicular to the contact line, and wherein the second nozzle has a second symmetry axis that is perpendicular to the contact line, wherein the first symmetry axis and the second symmetry axis contact each other at the contact line. The invention furthermore refers to a method of producing a structuring fabric having at least one structuring-bead resting on at least one sublayer-bead by using such an extrusion die.
