Abstract
Description
Die Erfindung betrifft einen Schmucksteinverbund und ein Verfahren zu dessen Herstellung.The invention relates to a gem stone composite and a method for its production.
Aus der DE-A-2 452 250 ist bereits ein Schmucksteinverbund bekannt, bei dem mehrere Schmucksteine mittels einer Schmelzklebstoffschicht zusammengefaßt werden, die die Setzseite der Steine umfaßt. Aus der gleichen Druckschrift ist auch ein verfahren zur Herstellung des Schmudesteinverbundes bekannt. Nachteilig ist bei diesen bekannten Steinverbunden, daß bei Aufbringen auf eine plane, nicht eindrückbare Oberfläche eines Substrats, die Schmelzklebstoffschicht nur an der unteren Steinspitze mit der Substratorberfläche in Verbindung steht und somit nur eine schlechte Verklebung erreicht werden kann.From DE-A-2 452 250 a gemstone composite is already known, in which several gemstones are combined by means of a hot-melt adhesive layer which comprises the set side of the stones. From the same publication a method for producing the Schmudesteinverbund is known. A disadvantage of these known stone composites is that when applied to a flat, non-indentable surface of a substrate, the hotmelt adhesive layer is only in contact with the substrate surface at the lower stone tip and thus poor adhesion can be achieved.
Für manche Anwendungszwecke ist eine Schmelzklebstoffschicht nicht vorteilhaft, da die Aktivierungstemperatur zu hoch ist, und das mit dem Schmucksteinverbund zu versehene Material beeinträchtigt wird. Dies ist biespielsweise bei empfindlichen Textilmaterialien, sowie Schmuck aus Schleuderguß oder Kunstoff, der Fall.For some applications, a hot melt adhesive layer is not advantageous because the activation temperature is too high and the material to be provided with the gem stone composite is impaired. This is the case, for example, with sensitive textile materials, as well as jewelry made from centrifugal casting or plastic.
Der Erfindung liegt die Aufgabe zugrunde, einen Schmucksteinverbund zu schaffen, der auf einfache Weise auf ein Substrat ohne Beeinträchtigung desselben aufgebracht werden kann, wobei eine ausreichende Verklebung zwischen Schmucksteinverbund und Substrat gewährleistet ist.The invention has for its object to provide a gemstone composite that can be easily applied to a substrate without affecting the same, with sufficient bonding between the gemstone composite and substrate is guaranteed.
Der Erfindung liegt die Erkenntnis zugrunde, daß diese Aufgabe dadurch gelöst werden kann, daß die Klebefläche des Schmucksteinverbundes im wesentlichen plan ausgebildet wird.The invention is based on the knowledge that this object can be achieved in that the adhesive surface of the gem stone composite is essentially flat is trained.
Gegenstand der Erfindung ist ein Schmucksteinverbund aus mehreren Schmucksteinen, die eine Schmelzklebstoffschicht tragen, der dadurch gekennzeichnet ist, daß die Schmucksteine auf ihrer Setzseite eine erste Schmelzklebstoffschicht tragen, darunter eine Füllschicht, die die Zwischenräume zwischen den einzelnen Steinen ausfüllt und darunter eine zweite Schmelzklebstoffschicht, die im wesentlichen plan ist und mit der ersten Schmelzklebstoffschicht im Bereich der Spitzen der Schmucksteine verschweißt ist, angeordnet sind.The invention relates to a gemstone composite comprising a plurality of gemstones which carry a layer of hotmelt adhesive, which is characterized in that the gemstones have a first layer of hotmelt adhesive on their set side, including a filler layer which fills the spaces between the individual stones and underneath a second layer of hotmelt adhesive which is essentially flat and is welded to the first hot melt adhesive layer in the area of the tips of the gemstones.
Gegenstand der Erfindung ist ferner ein Verfahren zur Herstellung eines Schmucksteinverbundes, wobei mehrere Schmucksteine auf ihrer Setzseite mit einer Schmelzklebstoffschicht versehen werden, dadurch gekennzeichnet daß auf diese Schmelzklebstoffschicht eine Füllschicht zum Füllen der Zwischenräume zwischen den einzelnen Schmucksteinen und eine zweite Schmelzklebstoffschicht aufgebracht werden, und die beiden Schmelzklebstoffschichten im Bereich der Spitzen der Schmucksteine auf der Setzseite verschweißt werden.The invention further relates to a process for the production of a gemstone composite, wherein a plurality of gemstones are provided with a hotmelt adhesive layer on their setting side, characterized in that a filling layer for filling the spaces between the individual gemstones and a second hotmelt adhesive layer are applied to this hotmelt adhesive layer, and the two Hot melt adhesive layers in the area of the tips of the gemstones are welded on the setting side.
Der erfindungsgemäße Schmucksteinverbund zeichnet sich dadurch aus, daß die durch die zweite Schmelzklebstoffschicht gebildete Klebefläche im wesentlichen plan ist. Somit kann bei Auflegen des Schmucksteinverbundes auf ein Substrat und Aktivierung der Schmelzklebstoffschicht, weil eine Verklebung über die ganze Fläche erfolgt, eine optimale Klebefestigkeit erzielt werden.The gemstone composite according to the invention is characterized in that the adhesive surface formed by the second hot melt adhesive layer is essentially flat. Thus, when the gem stone composite is placed on a substrate and the hot-melt adhesive layer is activated, because adhesive is applied over the entire surface, optimum adhesive strength can be achieved.
Ein ganz wesentlicher Vorteil des erfindungsgemäßen Schmucksteinverbundes ist die Tatsache, daß dieser leicht verformbar ist und somit allen Arten von Flächen leicht anpaßbar ist. Dies beruht darauf, daß sämtliche Schichten des Verbundes leicht verformbar bzw. biegbar sind.A very important advantage of the gemstone composite according to the invention is the fact that it is easily deformable and therefore easy on all types of surfaces is customizable. This is due to the fact that all layers of the composite are easily deformable or bendable.
Vorzugsweise wird zwischen der ersten Schmelzklebstoffschicht und der Füllschicht eine Effektschicht angeordnet, die den Zwischenräumen zwischen den einzelnen Schmucksteinen ein gewünschtes, beispielsweise silbern glänzendes, Aussehen verleiht.An effect layer is preferably arranged between the first hot melt adhesive layer and the filler layer, which gives the spaces between the individual gemstones a desired, for example silvery, appearance.
Besondere Vorteile bringt der erfindungsgemäße Schmucksteinverbund in jenen Fällen, bei denen die Aktivierung einer Schmelzklebstoffschicht das Material des Substrats beeinträchtigen würde. In einem solchen Fall wird die Haftung mit dem Substrat nicht über die Schmelzklebstoffschicht sondern über eine Selbstklebeschicht oder andere bereits auf den Schmucksteinverbund aufgebrachte oder nachträglich aufbringbare Klebstoffschicht erzielt. Gemäß einer bevorzugten Ausführungsform wird deshalb auf der zweiten Schmelzklebstoffschicht eine Selbstklebeschicht angeordnet.The gemstone composite according to the invention brings particular advantages in those cases in which the activation of a hotmelt adhesive layer would impair the material of the substrate. In such a case, the adhesion to the substrate is not achieved via the hotmelt adhesive layer but rather via a self-adhesive layer or another adhesive layer that has already been applied to the gem stone composite or can be subsequently applied. According to a preferred embodiment, a self-adhesive layer is therefore arranged on the second hot melt adhesive layer.
Die erste Schmelzklebstoffschicht, die die Setzseite der Schmucksteine wie eine Fassung umgibt, kann diskontinuierlich sein, d.h. die einzelnen Schmucksteine sind nicht durch eine Schmelzklebstoffolie verbunden, sondern tragen lediglich eine Art Fassung aus Schmelzklebstoffschicht. Sie kann aber auch kontinuierlich sein. Vorzugsweise ist diese erste Schmelzklebstoffschicht transparent.The first layer of hot melt adhesive, which surrounds the set side of the gemstones like a setting, can be discontinuous, i.e. the individual gemstones are not connected by a hot-melt adhesive film, but only carry a kind of frame made of hot-melt adhesive layer. But it can also be continuous. This first hot melt adhesive layer is preferably transparent.
Die Füllschicht besteht vorzugsweise aus einem leicht deformierbaren Material,wie einen Schaumstoff, und ist vorzugsweise auf beiden Seiten mit einer Selbstklebeschicht versehen. Die Dicke der Füllschicht entspricht vorzugsweise etwa der Höhe des Fassungsabschnittes der Schmucksteine.The filling layer preferably consists of an easily deformable material, such as a foam, and is preferably provided with a self-adhesive layer on both sides. The thickness of the filler layer preferably corresponds approximately to the height of the setting section of the gemstones.
Als Selbstklebeschicht kommen alle bekannten Selbstklebeschichten in Frage. Vorzugsweise wird die Selbstklebeschicht in Form einer Zwischenschicht,die auf beiden Seiten eine Selbstklebeschicht trägt, aufgebracht.All known self-adhesive layers can be used as self-adhesive layers. The self-adhesive layer is preferably applied in the form of an intermediate layer which carries a self-adhesive layer on both sides.
Als Schmucksteine kommen insbesondere geschliffene Glassteine, vorzugsweise Chatons aus Kristallglas, in Betracht.In particular, cut glass stones, preferably chatons made of crystal glass, come into consideration as gemstones.
Bei der Herstellung des Schmucksteinverbundes können die einzelnen Schichten einzeln aufgebracht werden, es wird jedoch bevorzugt, diese, mit Ausnahme der ersten Schmelzklebstoffschicht, in Form einer vorgefertigten Verbundschicht aufzubringen, die vorzugsweise aus Effktschicht, Füllschicht mit Selbstklebeschichten auf beiden Seiten und Schmelzklebstoffschicht und gegebenenfalls Selbstklebeschicht und gegebenenfalls Abdeckschicht besteht.In the production of the gem stone composite, the individual layers can be applied individually, but it is preferred to apply them, with the exception of the first hot melt adhesive layer, in the form of a prefabricated composite layer, which preferably consists of an effect layer, filler layer with self-adhesive layers on both sides and hot melt adhesive layer and optionally self-adhesive layer and optionally there is a covering layer.

Oberhalb der Schmucksteine 1 ist eine Verbundfolie 24 gezeigt. Diese besteht, in Richtung von den Steinen nach oben gesehen, aus folgenden Schichten: Einer Effekt schicht 4, einer Füllschicht 5, einer zweiten Schmelzklebstoffschicht 7, einer Selbstklebeschicht 9 und einer Abdeckschicht 20.A
Oberhalb der Verbundfolie 24 ist der Preßkopf 18 mit Schneidmessern 19 gezeigt.The
Die Schmucksteine sind vorzugsweise geschliffene Glassteine, insbesondere Chatons aus Kristallglas.The gemstones are preferably cut glass stones, in particular chatons made of crystal glass.
Für die Schmelzklebstoffschichten können alle geeigneten, durch Wärme aktivierbaren Kunststoffe verwendet werden, insbesondere Polyamide, Polyesterharze, Epoxidharze, Isocyanate und Aminoplaste. Die Dicke der Schmelzklebstoffschicht liegt üblicherweise im Bereich von 20 bis 100 µm.All suitable plastics which can be activated by heat can be used for the hot-melt adhesive layers, in particular polyamides, polyester resins, epoxy resins, isocyanates and aminoplasts. The thickness of the hot melt adhesive layer is usually in the range from 20 to 100 μm.
Die erste Schmelzklebstoffschicht 3 umfaßt die Schmucksteine 1 in ihrem Fassungsabschnitt 14. Vorzugsweise reicht die Schmelzklebstoffschicht über den Äquator der Schmucksteine 1, sodaß zusätzlich zur Klebehaftung eine stabilere Verbindung zwischen Schmuckstein 1 und Schmelzklebstoffschicht 3 durch Umgreifen gegeben ist. Die Schmelzklebstoffschicht 3 kann diskontinuierlich ausgebildet sein, wobei dann die Setzseite 2 der Schmucksteine 1 mit Schmelzklebstoffhütchen umgeben ist. Diese sind in Figur 1 gezeigt. Alternativ können die Schmucksteine 1 von einer kontinuierlichen Schmelzklebstoffschicht 3 umfaßt werden, wie dies in Figur 3 gezeigt ist, wobei auch zwischen den Steinen eine Schmelzklebstoffschicht vorliegt.The first hot-melt
Die Schmelzklebstoffschicht ist vorzugsweise farblos und transparent.The hot melt adhesive layer is preferably colorless and transparent.
Auf die erste Schmelzklebstoffschicht wird eine Effktschicht 4 aufgebracht. Die Effektschicht hat den Zweck, den Zwischenräumen zwischen den Schmucksteinen 1 in Draufsicht eine bevorzugte optische Erscheinung zu geben, d.h. insbesondere die darunterliegenden dunklen, bzw. unansehnlichen Schichten abzudecken. Eine solche Effektschicht kann entfallen, wenn das optische Aussehen der anderen Schicht zufriedenstellend ist oder bei dem gewünschten Anwendungszweck dieser Aspekt von untergeordneter Bedutung ist.An effect layer 4 is applied to the first hot melt adhesive layer. The effect layer has the purpose of giving the spaces between the gemstones 1 a preferred optical appearance in plan view, i.e. especially to cover the underlying dark or unsightly layers. Such an effect layer can be omitted if the optical appearance of the other layer is satisfactory or if this aspect is of minor importance for the desired application.
Als Effektschicht 4 kommen insbesondere Metallfolien, wie Goldfolien, Aluminiumfolien oder bedampfte Polyesterfolien mit Metalleffekt oder farbige Kunststoffolien in Betracht.As the effect layer 4, in particular metal foils such as gold foils, aluminum foils or vapor-coated polyester foils with a metallic effect or colored plastic foils come into consideration.
Die Dicke der Effektfolien liegt insbesondere im Bereich von 5 bis 30 µm.The thickness of the effect films is in particular in the range from 5 to 30 μm.
Diese geringen Dicken gewährleisten, daß die Folie bei der Herstellung des Schmucksteinverbundes im Bereich der Spitzen 8 der Schmucksteine 1 reißt und im fertigen Schmucksteinverbund im wesentlichen nur im Bereich zwischen den Schmucksteinen 1 und daran angrenzend an den Schmucksteinen vorliegt. In diese Position wird die Effektfolien 4 bei der Herstellung des Schmucksteinverbundes durch die Füllschicht 5 gedrückt.These small thicknesses ensure that the film tears in the area of the tips 8 of the
Die Füllschicht 5 besteht vorzugsweise aus einem leicht komprimierbaren Material, insbesondere einem Schaumstoff. Besonders geeignet ist geschäumtes Moltopren, wie es in Form von Montagebändern im Handel ist. Solche Montagebänder weisen beidseitig eine Selbstklebstoffschicht auf. Die Verwendung einer Füllschicht mit beidseitigen Selbstklebeschichten ist vorteilhaft, da dann auf einfache Weise die aufzubringenden Schichten zu einer Verbundfolie vorgefertigt werden könne. Auch wird die Haftung zwischen der Füllschicht und den daran angrenzenden Schichten verbessert.The
Die Füllschicht 5 dient zum einen dazu, die Effektschicht 4 in richtige Position zu bringen, und ferner dazu durch Ausfüllen im wesentlichen des gesamten Zwischenraums 6 zwischen den Schmucksteinen 1 eine durchgehende Ebene vorzusehen, sodaß die zweite Schmelzklebstoffschicht 7 im wesentlichen plan zu liegen kommt. Dies ist wesentlich, da durch die plane Anordnung die gesamte Fläche des Schmucksteinverbundes zur Verklebung zur Verfügung steht und dadurch eine bestmögliche Verbindung mit Substraten gewährleistet ist, die aus Materialien bestehen, die wenig deformierbar sind.The
Die Dicke der Füllschicht 5 richtet sich nach der Größe der Schmucksteine 1, und zwar soll die Dicke vorzugsweise in etwa der Höhe des Fassungsabschnitts 14 der Schmucksteine 1 entsprechen. Gemäß einer bevorzugten Ausführungsform ist auf der zweiten Schmelzklebstoffschicht 7 eine Selbstklebeschicht 9 vorgesehen.The thickness of the
Die Selbstklebeschicht kann beispielsweise in Form einer Zwischenschicht vorliegen, die beidseitig Selbstklebstoff trägt. Die Selbstklebstoffschicht kann nachträglich auf die zweite Schmelzklebstoffschicht oder das Substrat aufgebracht werden. Bei Vorliegen einer Selbstklebeschicht wird vorzugsweise eine Abdeckschicht 20 vorgesehen, die aus Papier oder Kunststoff, vorzugsweise silikonbeschichtetem Papier, bestehen kann.The self-adhesive layer can, for example, be in the form of an intermediate layer which carries self-adhesive on both sides. The self-adhesive layer can subsequently be applied to the second hot-melt adhesive layer or the substrate. If a self-adhesive layer is present, a
Bei Verwendung einer Zwischenschicht besteht diese vorzugsweise aus dem gleichen Material wie die Füllschicht 5, also vorzugsweise aus einer Schaumstoffschicht mit Selbstklebeschichten auf beiden Seiten.If an intermediate layer is used, it preferably consists of the same material as the
Gemäß einer bevorzugten Ausführungsform werden die Schmucksteinverbunde in einer Presse hergestellt. Dabei wird unter erhöhtem Druck, beispielsweise 2 bis 3 bar Überdruck, die Verbundfolie 24 oder einzelne gewünschte Schichten, auf die auf dem Preßtisch 17 angeordneten Schmucksteine 1 mittels dem Preßkopf 18 gepreßt.According to a preferred embodiment, the gem stone composites are produced in a press. The
Während des Verpreßvorganges wird außerdem vorzugsweise mit Ultraschall bestrahlt. Der Ultraschall bewirkt eine Aktivierung der Polymerisate der Schmelzklebstoffschichten, die miteinander verschweißt werden. Das Verschweißen tritt im wesentlichen nur im Bereich der Spitze 8 der Schmucksteine 1 ein. Durch die Verbindung der ersten Schmelzklebstoffschicht 3 mit der zweiten Schmelzklebstoffschicht 7 wird ein stabiler Schmucksteinverbund mit fester Haftung der Schmucksteine 1 darin erhalten.During the pressing process, it is also preferably irradiated with ultrasound. The ultrasound activates the polymers of the hotmelt adhesive layers, which are welded together. The welding occurs essentially only in the area of the tip 8 of the
In Figur 2 ist der fertige Schmucksteinverbund 22 auf der Transferfolie 16 gezeigt. Der Schmucksteinverbund wurde mittels der Schneidmesser 19 abgeschnitten, die jedoch nicht die Transferfolie 16 durchschnitten haben, sondern auf Anschlag geführt wurden. Auf diese Weise können eine Vielzahl von Schmucksteinverbunden auf einer Transferfolie zur weiteren Verwendung angeordnet werden. Die Preßluftzuführungen 21 dienen zum Ausstoßen des Schmucksteinverbundes 22 aus dem Preßkopf 18.The
In Figur 3 ist in ähnlicher Weise wie in Figur 4 die Herstellung eines Schmucksteinverbundes gezeigt, wobei jedoch die Schmucksteine 1 über eine durchgehende Schmelzklebstoffschicht 3 miteinander verbunden und gehalten sind. Die Schmelzklebstoffschicht 3 umfaßt den Fassungsabschnitt 14 der Schmucksteine 1. Die Schmucksteine sitzen auf dem Preßtisch 17, der auch die Schneidmesser 19 trägt.In FIG. 3, the production of a gemstone composite is shown in a manner similar to that in FIG. 4, but the
Die Schichten werden in Form einer Verbundfolie 24 mittels Preßkopf 18 auf die Schmucksteine 1 aufgepreßt.The layers are pressed onto the
Der fertige Schmucksteinverbund ist in Figur 4 gezeigt, wo wiederum erkenntlich ist, daß die Schneidmesser 19 die Abdeckschicht 20 nicht durchschneiden, damit mehrere Schmucksteinverbunde auf einer Folie verbleiben können, wie dies in Figur 5 gezeigt ist, wo ein ganz dargestellter Schmucksteinverbund 22 und ein nur teilweise dargestellter Schmucksteinverbund 22′ auf einer gemeinsamen Abdeckschicht 20 angeordnet sind.The finished gemstone composite is shown in FIG. 4, where it can again be seen that the cutting
In Figur 6 ist eine Ausführungsform gezeigt, bei der die Schmucksteine 1 in Ausnehmungen 23 in einem als Lochplatte ausgebildeten Preßtisch 17 angeordnet sind. Dieser trägt auch die Schneidmesser 19. Die Verbundfolie 24 wird mittels Preßkopf 18, der auch als Sonotrode für den Ultraschall ausgebildet ist, auf die mit Schmelzklebstoffschicht 3 versehenen Schmucksteine 1 gepreßt.FIG. 6 shows an embodiment in which the
In Figur 7 ist eine Ausführungsform gezeigt, bei der auf einem Preßtisch 17 die Verbundfolie 24 aufgelegt wird. Darüber werden die mit Schmelzklebstoffschicht 3 versehenen Schmucksteine 1 in gewünschter Anordnung auf einer Transferfolie 16 aufgelegt. Danach wird mittels Preßkopf 18 mit Schneidmessern 19 gepreßt und die mit den Steinen verpreßten Folien mit den Schneidmessern 19 bis zur Abdeckschicht 20 abgeschnitten.FIG. 7 shows an embodiment in which the
Der erfindungsgemäße Schmucksteinverbund eignet sich für die verschiedensten Verwendungszwecke, wie zum Applizieren auf Textilien, Leder oder für Modeschmuck.The gemstone composite according to the invention is suitable for a wide variety of uses, such as for application on textiles, leather or for costume jewelry.
Der Schmucksteinverbund ist besonders zur Schmuckherstellung in jener Ausführungsform mit Zwischenschicht 9 mit selbstklebender Beschichtung geeignet. Bei diesen Ausführungsformen muß lediglich die Abdeckschicht 20 abgezogen werden, und der Schmucksteinverbund wird an geeigneter Stelle am Modeschmuck, insbesondere in vorgesehene Vertiefungen, eingesetzt, wo er mittels der auf der Zwischenschicht 9 vorgesehenen selbstklebenden Schicht ausreichend haftet.The gem stone composite is particularly suitable for jewelry production in that embodiment with an
So gestaltete Schmucksteinverbunde sind plan aber auch krümmbar, d.h. zum Beispiel zylindrischen Flächen anformbar.Gemstone composites designed in this way can also be bent flat, i.e. For example, cylindrical surfaces can be formed.
Da bei Selbstklebeschichten eine Erwärmung nicht erforderlich ist, können temperaturempfindliche Materialien, wie Kunststoff oder Schleuderguß, auf einfache Weise mit den erfindungsgemäßen Schmucksteinverbunden versehen werden.Since heating is not required in the case of self-adhesive layers, temperature-sensitive materials, such as plastic or centrifugal casting, can be provided in a simple manner with the gemstones according to the invention.
