Definitions
- the invention relates to a method in Preamble of claim 1 mentioned type for processing a metallic surface.
- embossing surface of an embossing roller is first produces a silicone cast from a natural template, on the surface of which there is such a negative Deep coarse structure is located, after which by repeated Cast produced a positive of the deep coarse structure the surface of which is covered with a conductive layer is provided, in a galvanic way metallic layer, usually nickel, applied becomes. After the galvanic application process has ended the positive is removed and so the metallic Embossed surface with the negative of the deep coarse structure exposed to the template. It is known afterwards the embossing surface by irradiating particles or etching or the like with a deep fine structure to provide her with such a weariness lend that give the impression of natural leather should.
- DE 196 36 801 A1 is a method of im
- the preamble of claim 1 is known, where a steel band through several treatment chambers is moved in which sandblasters are arranged that are on the surface of the tape material act. Due to the multiple irradiation Irradiation effect increased. A different one Irradiation from the various sandblasting fans does not happen.
- the invention is based on the object The method mentioned in the preamble of claim 1 kind of processing a metallic surface to create with which a product can be shaped, whose Surface in appearance a higher degree of agreement with the natural template.
- the basic idea of the invention is the surface to form an embossed surface with a deep coarse structure and the heights and valleys of the Deep coarse structure with a different deep fine structure, different roughness, too provided, creating a higher level of agreement between the embossed surface and the surface a template, e.g. B. natural leather.
- the method according to the invention first the entire, the deep coarse structure embossed surface with a deep fine structure with a first roughness depth, after which then the one with the deep fine structure with the first Surface provided with a roughness in the area of the valleys of the deep coarse structure with a protective layer which is the embossing surface in the area of the valleys protects if according to a further process step the heights protruding from the protective layer the deep coarse structure by irradiation with particles or etching or the like with a deep fine structure provided with a second roughness depth becomes.
- the embossing surface has its shape according to the invention, where the highs and valleys of the deep coarse structure different deep fine structures, so Roughness or gloss levels.
- the degree of roughness can vary and either the highs can be a deep fine structure with a lower surface roughness than the valleys or the other way around.
- An advantageous embodiment of the invention provides that the protective layer over heights and valleys of the deep coarse structure applied away and then the protective layer in Removed area of heights of coarse structure becomes. This removal can be advantageous by wiping or wiping, preferably under Use of an agent softening the protective layer, respectively.
- Fig. 1 shows a small section in section an embossing roller 2, the surface 4 valleys 6 and Heights 8 has.
- a transport medium either air or a liquid
- Particles 12 directed onto the surface 4 the size and nature of these particles so is chosen that that achieved by the radiation Deep fine structure a relatively low roughness Has.
- a protective layer 14 being applied to the surface 4 has been spread over the valleys 6 and Extends heights 8.
- the protective layer can it is a protective lacquer that is sprayed on has been.
- FIG. 3 illustrates the subsequent method step, in which the protective layer 14 in the area the heights 8 has been removed, so that the Protective layer is only in the area of the valleys 6.
- Removing the protective layer from heights 8 can be done by wiping with the help of a Protective layer of softening agents.
- the protective layer 14 in liquid Form by means of a squeegee to be applied when applying sweeps over the heights 8, so that there no material of the protective layer remains.
- FIG. 4 illustrates the further method step, with the coarser particles by means of the nozzle 10 16 are irradiated onto the surface, whereby only the exposed heights 8 and so with be provided with a roughness that has a greater roughness depth has than that in the method step according to Fig. 1 generated roughness over the entire surface.
- Fig. 5 shows the surface 4 after removing the Protective layer from the valleys 6 so that the surface 4 forms an embossed surface with a rough structure with valleys 6 and heights 8 that are in the range of heights is overlaid by a deep fine structure, the Roughness is greater, preferably much greater than that of the deep fine structure in the area of the valleys 6.
- Fig. 6 illustrates the use of the embossing roller 2 for embossing a thermoplastic film 18 under Heat and pressure.
- 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.
- 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.

Abstract
Description
- Die Fig. 1 bis 5
- verdeutlichen aufeinanderfol gende Schritte des erfindungsgemäßen Verfahrens,
- Fig. 6
- dient der Erläuterung der Verwendung der erfindungsgemäßen Prägeoberfläche und
- Fig. 7
- zeigt vergrößert eine Einzelheit aus Fig. 6.
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.
