Fig. 7 zeigt in vergrößerter Darstellung die geprägte Folie 18, deren Oberfläche 20 ein Positiv der Oberflächenstruktur einer Ledervorlage aufweist, wäh
rend die Oberfläche 4 der Prägewalze 2 in bekannter Weise ein Negativ der Vorlage des natürlichen Leders darstellt. Somit weist die Oberfläche 20 der in Fig. 7 dargestellten Folie 18 eine Grobstruktur entsprechend der Vorlage aus natürlichem Leder auf, deren Höhen 22 eine Tiefenfeinstruktur mit einer geringen Rauhtiefe aufweist, so daß die Höhen 22 schwach glänzend erscheinen, wie das bei natürlichem Leder aufgrund von Abnutzung der Fall ist, während in den nicht abgenutzten Tälern 24 die Tiefenfeinstruktur eine größere Rauhtiefe hat, so daß die Täler matter erscheinen als die Höhen 22.FIG. 7 shows an enlarged representation of the embossed film 18, the surface 20 of which has a positive of the surface structure of a leather template, while
rend the surface 4 of the embossing roller 2 in a known manner represents a negative of the original leather. Thus, the surface 20 of the film 18 shown in FIG. 7 has a rough structure corresponding to the template made of natural leather, the heights 22 of which have a deep fine structure with a low roughness, so that the heights 22 appear slightly glossy, as is the case with natural leather due to Wear is the case, while in the non-worn valleys 24 the deep fine structure has a greater roughness depth, so that the valleys appear duller than the heights 22.

Mit dem erfindungsgemäßen Verfahren ist also die Oberfläche einer Prägewalze herstellbar, mit der eine Folie geprägt werden kann, die ein wesentlich höheres Maß an Ähnlichkeit mit einer Vorlage aus natürlichem Leder hat, als das bei bekannten Prägewalzen der Fall war.With the method according to the invention Surface of an embossing roller can be produced with which one Foil can be embossed, which is a much higher one Level of similarity to a natural template Leather is the case with known embossing rollers was.
