Description

Die Erfindung betrifft ein Verfahren zur Herstellung von Schmuck-, Dekorations-, und Kunstgegenständen aus einer Metallfolie oder aus einem Metallnetz mit unregelmäßig gefalteter Struktur, gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a method for producing jewelry, decoration, and Art objects made of a metal foil or a metal net with irregularly folded Structure according to the preamble of claim 1.

Bisher war das Herstellen von unregelmäßigen Faltstrukturen bei Schmuck-, Dekorations- und Kunstgegenständen aus Metall bzw. bei den Oberflächen solcher Gegenstände nur mit Hilfe von Modellen und Abgußtechniken möglich.Diese Arbeitsvorgänge sind langwierig und materialaufwendig, die damit herstellbaren Strukturen sind grob und unscharf.So far, the manufacture of irregular folding structures in jewelry, decoration and Art objects made of metal or on the surfaces of such objects only with the help of models and casting techniques possible. These operations are lengthy and material-intensive, the structures that can be produced with it are coarse and out of focus.

Zur Herstellung regelmäßiger Faltstrukturen bei verschiedenen Materialien, z.B. bei der Papierbearbeitung zur Herstellung von Wellpappe oder bei der Herstellung von Wellblech, ist es bekannt, die gewünschte Struktur mit Hilfe von Wulsten- oder Nutenwalzen in das Blech bzw. in die Papierbahn einzuprägen ( vgl. DE - OS 2042855, DE - OS 2107981, DE - OS 2932713 ). Ferner ist es bekannt, das gleichmäßig zu faltende Papier nach dem Durchlauf durch im wesentlichen glatte Walzen in einem Kanal zusammenzuschieben ( vgl. DE - AS 1028420 ). Die hierbei entstehenden gleichförmigen und regelmäßigen Faltstrukturen sind zur Herstellung von Schmuck- und kunstgewerblichen Gegenständen jedoch nur wenig von Interesse, da ihre gleichförmige Oberflächenstruktur langweilig wirkt. Auch die mit Hilfe von Wellungswalzen mit Profilierungen herstellbaren Strukturen aus Metallfolie ( vgl. DE - OS 3228181 ) weisen auf ihrer Oberfläche immer wiederkehrende identische Muster auf.For the production of regular folding structures with different materials, e.g. in the Paper processing for the production of corrugated cardboard or in the production of corrugated iron it is known the desired structure with the help of bead or grooved rollers in the sheet or to emboss into the paper web (see DE - OS 2042855, DE - OS 2107981, DE - OS 2932713). It is also known that the paper to be folded evenly after Passing pass through essentially smooth rollers in a channel (cf. DE - AS 1028420). The resulting uniform and regular folding structures are for the production of jewelry and handicrafts, however, little of Interest because their uniform surface structure looks boring. Even with the help of Corrugation rollers with structures that can be produced from metal foil (cf. DE-OS 3228181) have identical, recurring identical surfaces on their surface Pattern on.

Aus der US 1,751,471 ist eine Vorrichtung zum Falten von Papier bekannt, bei der die zu faltende Papierbahn durch einen Spalt zwischen zwei sich drehenden Walzen in einen Kanal geführt und dort zusammengeschoben und gefaltet wird. Am Ende des Kanals ist eine Stoppvorrichtung vorhanden, welche die fortlaufende Papierbahn beaufschlagt. Durch zurückziehen der federnd gelagerten Stoppvorrichtung läßt sich das gefaltete Papier aus dem Kanal entnehmen. Die CH 263044 beschreibt ein Verfahren zur Herstellung von regelmäßig gefalteter Wellpappe. Dabei wird eine Papierbahn ebenfalls zwischen zwei Walzen hindurch in einen Kanal geführt, wobei das lose Ende der Papierbahn zunächst mittels eines Aufstauchschiebers abgestoppt wird, der später entfernt wird. Beide Verfahren lassen sich nur bedingt für das Falten von Metallfolie verwenden. Eine nach dem Verfahren gemäß der CH 263044 bearbeitete Metallfolie weist eine regelmäßige und gleichförmige Faltenstruktur auf.From US 1,751,471 a device for folding paper is known in which the one to be folded Paper web through a gap between two rotating rollers into a channel guided and pushed together and folded there. At the end of the channel is one Stop device available, which acts on the continuous paper web. By withdrawing The spring-loaded stop device lets the folded paper out of the channel remove. CH 263044 describes a process for the production of regularly folded Corrugated cardboard. A paper web is also passed between two rollers in one Channel led, the loose end of the paper web first by means of an upswing is stopped, which will be removed later. Both methods can only be used conditionally for that Use folding metal foil. One processed according to the procedure in CH 263044 Metal foil has a regular and uniform fold structure.

Mit dem Verfahren gemäß der US 1,751,471 läßt sich eine etwas unregelmäßigere, aber dennoch nur sehr grobe Faltenstruktur erzeugen. Eine solche Struktur ist für die Verwendung der gefalteten Metallfolie zu Schmuckzwecken in der Regel noch zu grob, da für die meist sehr kleinen Schmuckgegenstände, z.B. für Ringe, deutlich feinere Strukturen benötigt werden.With the method according to US 1,751,471, a somewhat irregular, but nevertheless only produce a very rough fold structure. Such a structure is for the use of the folded metal foil for jewelry purposes is usually too coarse, because for the most very small jewelry items, e.g. for rings, significantly finer structures are needed.

Es ist daher die Aufgabe der vorliegenden Erfindung, ein Verfahren anzugeben, mit welchem Gegenstände aus einer Metallfolie oder aus einem Metallnetz mit unregelmäßig gefalteten, feinen Strukturen kostengünstig herstellbar sind.It is therefore the object of the present invention to specify a method with which Objects made from a metal foil or from a metal net with irregularly folded, fine Structures are inexpensive to manufacture.

Diese Aufgabe wird durch ein Verfahren mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Weiterbildungen sind in den Unteransprüchen gekennzeichnet.This object is achieved by a method having the features of patent claim 1. Advantageous further developments are characterized in the subclaims.

Für die Herstellung von Gegenständen mit unregelmäßig gefalteter Struktur wird vorteilhafterweise eine konventionelle Vorrichtung für das Walzen von Metallfolien verwendet, welche mit einer Stoppvorrichtung zum Stoppen einer Metallfolie oder eines Metallnetzes am Ende eines Kanals ausgestattet ist. Die Metallfolie oder das Metallnetz gelangt nach dem Hindurchtreten durch den Spalt zwischen den Walzen in diesen dünnen Kanal, in welchen sie durch die Walzen hinein- und dort unter Bildung einer unregelmäßigen Faltstruktur zusammengeschoben wird. Für diese preisgünstige Technik kann eine dünne Metallfolie, vorzugsweise aus Gold, Silber oder Kupfer, verwendet werden. Die Technik läßt sich aber auch bei Netzen aus Metallfäden, beispielsweise aus dünnen Gold-, Silber- oder Kupferfäden anwenden. Der Abstand, die Form und die Tiefe der einzelnen Falten läßt sich durch geeignete Materialauswahl, z.B. durch die Art und Dicke der verwendeten Metallfolie bzw. durch die Dicke der Metallfäden des Netzes, sowie durch die Wahl der Behandlungsbedingungen, wie z.B. durch die Drehgeschwindigkeit der Walzen oder durch die Breite des Kanals, variieren.For the production of objects with an irregularly folded structure is advantageous used a conventional device for rolling metal foils, which with a stopping device for stopping a metal foil or a metal net at the end of a Channel is equipped. The metal foil or the metal net passes after the passage through the gap between the rollers in this thin channel, in which they pass through the Rolls in and pushed together there to form an irregular folding structure becomes. A thin metal foil, preferably made of gold, Silver or copper can be used. The technology can also be used for networks Use metal threads, for example made of thin gold, silver or copper threads. The The distance, the shape and the depth of the individual folds can be determined by suitable ones Material selection, e.g. by the type and thickness of the metal foil used or by the Thickness of the metal threads of the network, as well as by the choice of treatment conditions, such as e.g. vary by the speed of rotation of the rollers or by the width of the channel.

Die mittels der beschriebenen Technik herstellbaren Gegenstände mit unregelmäßig gefalteter Struktur lassen sich durch Biegen und Formen auf vielfältige Weise zu Schmuck-, Dekorations-und Kunstgegenständen weiterverarbeiten, z.B. zu Ringen, Ohrringen, Broschen, Armbändern oder Halsketten. Auch eine Veredelung der gefalteten Metallfolie oder des gefalteten Metallnetzes vor der Weiterverarbeitung ist möglich. So läßt sich eine gefaltete Kupfer- oder Silberfolie beispielsweise nach dem Falten galvanisch vergolden. The objects which can be produced by means of the technique described with irregularly folded Bending and shaping can be used in a variety of ways to make jewelry, decoration and structure Process art objects, e.g. to rings, earrings, brooches, bracelets or necklaces. Also a refinement of the folded metal foil or the folded one Metal mesh before further processing is possible. So a folded copper or Gild silver foil, for example, after folding.

  • Für die Herstellung von Gegenständen mit unregelmäßig gefalteter Struktur läßt sich vorteilhafterweise eine durch eine Stoppvorrichtung ergänzte Maschine für das Walzen von Metallfolien verwenden, beispielsweise eine Walzenmaschine für Goldschmiede, wie sie von der Firma H. Seltsam & Sohn in Pforzheim angeboten wird. Eigens für das Herstellen von Gegenständen mit unregelmäßig gefalteter Struktur gebaute Vorrichtungen sind jedoch ebenfalls denkbar.For the production of objects with an irregularly folded structure can advantageously be a machine for the rolling of Use metal foils, for example a roller machine for goldsmiths, such as from the company H. Seltsam & Sohn in Pforzheim. Especially for the production of However, devices built with irregularly folded structure are also devices conceivable.

    Die verwendete Vorrichtung weist zwei glatte, drehbare Walzen 2, 3 auf, wobei die obere Walze 2 mittels einer ( nicht gezeigten ) Verstellvorrichtung in Richtung des Pfeils 9 höhenverstellbar ist. Dadurch läßt sich die Breite eines Spalts 5 zwischen den Walzen 2, 3 festlegen, beispielsweise auf 0,03 oder auf 0,4 mm. Die Vorrichtung weist eingangsseitig eine Zuführungsplatte 6 für die Metallfolie 1 und ausgangsseitig eine Führungsplatte 7 auf. Auf der Ausgangsseite der Vorrichtung ist ferner eine Abdeckplatte 8 für die obere Walze 2 vorhanden. Diese bildet mit der Führungsplatte 7 einen Kanal 10. Auf der Führungsplatte 7 oder an der Abdeckplatte 8 ist eine Stoppvorrichtung 4, vorzugsweise eine Stahlplatte, festlegbar oder feststellbar ( Fig. 1).The device used has two smooth, rotatable rollers 2, 3, the upper one The height of the roller 2 can be adjusted in the direction of the arrow 9 by means of an adjusting device (not shown) is. This allows the width of a gap 5 between the rollers 2, 3 to be determined, for example 0.03 or 0.4 mm. The device has one on the input side Feed plate 6 for the metal foil 1 and a guide plate 7 on the output side. On the A cover plate 8 for the upper roller 2 is also provided on the outlet side of the device. This forms a channel 10 with the guide plate 7. On the guide plate 7 or on the Cover plate 8 is a stop device 4, preferably a steel plate, which can be fixed or locked (Fig. 1).

    Die Herstellung eines Gegenstandes mit unregelmäßig gefalteter Struktur, wie er in Fig. 2 dargestellt ist, läßt sich beispielsweise wie folgt durchführen :The manufacture of an article with an irregularly folded structure, as shown in Fig. 2 can be carried out as follows, for example:

    Der Anfang einer Silberfolie 1 mit einer Dicke von 0,05 mm wird mittels der Zuführungsplatte 6 zwischen den beiden drehbaren Walzen 2, 3 hindurchgeführt, wobei sich die höhenverstellbare obere Walze 2 in angehobenem Zustand befindet. Danach wird die Silberfolie 1 um die Abdeckplatte 8 herumgeknickt, worauf das Ende der Silberfolie 1 mittels der Stoppvorrichtung 4, bei der es sich um eine Stahlplatte handelt, in Richtung des Pfeils 11 an die Abdeckplatte 8 angedrückt wird ( Fig. 1). Durch die Befestigung der Stoppvorrichtung 4 auf der Führungsplatte 7 oder an der Abdeckplatte 8 wird gleichzeitig der Ausgang des Kanals 10 zwischen der Führungsplatte 7 und der Abdeckplatte 8 verschlossen. Danach wird die höhenverstellbare Walze 2 so weit abgesenkt, daß infolge einer Verkleinerung des Spalts 5 zwischen den Walzen 2, 3 diese nunmehr auf die Metallfolie 1 drücken. The start of a silver foil 1 with a thickness of 0.05 mm is by means of the feed plate 6 passed between the two rotatable rollers 2, 3, the height adjustable upper roller 2 is in the raised state. Then the silver foil 1 around the Cover plate 8 bent, whereupon the end of the silver foil 1 by means of the stop device 4, which is a steel plate, in the direction of arrow 11 on the cover plate 8 is pressed (Fig. 1). By attaching the stop device 4 on the Guide plate 7 or on the cover plate 8 is the output of the channel 10 between the guide plate 7 and the cover plate 8 closed. Then the height adjustable Roller 2 lowered so far that due to a reduction in the gap 5 between the rollers 2, 3 now press them onto the metal foil 1.

    Danach werden die beiden Walzen 2, 3 unter Beibehaltung des Stoppzustandes für die Metallfolie 1 gedreht, beispielsweise mit einer Rollgeschwindigkeit von 25 Umdrehungen pro Minute. Während der Bearbeitungszeit der Metallfolie 1, die beispielsweise 30 Sekunden betragen kann, wird weitere Folie, beispielsweise 0,5 m Silberfolie zwischen den Walzen 2, 3 in den Kanal 10 nachgeführt und dort unregelmäßig nachgeschoben und gefaltet. Nach dem Lösen der Stoppvorrichtung 4 kann die Metallfolie 1 mit unregelmäßig gefalteter Struktur ( Fig. 2 ) aus der Vorrichtung entnommen und zu Schmuckstücken ( Fig. 3 ) verarbeitet werden.Then the two rollers 2, 3 while maintaining the stop state for the Rotated metal foil 1, for example at a rolling speed of 25 revolutions per Minute. During the processing time of the metal foil 1, for example 30 seconds may be, further film, for example 0.5 m silver film between the rollers 2, 3 tracked in channel 10 and pushed and folded irregularly there. After this The metal foil 1 with an irregularly folded structure (FIG. 2) removed from the device and processed into jewelry (Fig. 3).
