Description
Nach dem bisherigen Stande der Technik ist eine Verschweißung von Kunststoffolien mit einer zur Versteifung dienenden Einlage, z. B. bei Buch- und Mappendeckeln, nur in der Weise bekannt, daß die über die Einlagen hinausragenden Ränder der Folien zusammengeschweißt werden. Hierbei ergeben sich zwangläufig vorstehende Schweißränder, die im Gebrauch wenig angenehm sind und einen Nachteil gegenüber den festen, scharfen Kanten von aus anderen Materialien hergestellten Buchbindererzeugnissen od. dgl. haben. Ebenso war es bisher nicht möglich, auf Kunststoffolien mit eingeschweißten Versteifungseinlagen mittels Hochfrequenz eine einwandfreie Blind- oder Goldprägung vorzunehmen, da der Hochfrequenzstrom beim Prägevorgang die Einlage nur schwer oder gar nicht durchdringen kann. According to the previous state of the art, a welding of Plastic films with an insert used for stiffening, e.g. B. with book and Portfolio covers, only known in such a way that those protruding beyond the inlays Edges of the foils are welded together. This inevitably results in the foregoing Welded edges that are not very pleasant in use and have a disadvantage compared to this the firm, sharp edges of bookbinding products made from other materials or the like. Likewise, it was previously not possible to use welded-on plastic films Reinforcement inserts by means of high frequency a perfect blind or gold embossing to make, since the high-frequency current during the embossing process the deposit only with difficulty or cannot penetrate at all.
Die Erfindung hat nun eine Versteifungseinlage aus Pappe, Karton, Holz oder ähnlichen Werkstoffen für Gegenstände aus Kunststoffolien zum Gegenstand, die durch Hochfrequenz mit Schweißnähten oder Prägungen versehen werden. Das besondere Merkmal dieser Einlagen besteht darin, daß auf die Einlage mindestens einseitig eine metallische Schicht aufgebracht ist. The invention now has a stiffening insert made of cardboard, Wood or similar materials for objects made of plastic foils to the object, which are provided with welding seams or embossing by high frequency. The special The feature of these deposits is that the deposit is at least one-sided a metallic layer is applied.
Diese Metallschicht ersetzt infolge ihrer Kondensatorwirkung die Schweiß-Grundelektrode, so daß die Hochfrequenz beim Schweißvorgang die Einlage nicht zu durchdringen braucht. Hierdurch wird ein Durchwärmen der Einlage vermieden und die Schweiß zeit trotz dickster Einlagen normal gehalten. Due to its capacitor effect, this metal layer replaces the Welding base electrode, so that the high frequency during the welding process the insert does not need to penetrate. This prevents the insert from heating up and the sweat time kept normal despite the thickest deposits.
Die Vorteile, welche der Gegenstand der Neuerung bietet, liegen darin, daß es nunmehr möglich ist, den sonst außen an den Einlagen stehenbleibenden Schweißrand zu vermeiden und statt dessen die Kanten um die Einlagen herum so einzuschweißen, daß die Kunststoffolie um die Ränder der Einlage herumgelegt wird. Die Schweißnaht liegt daher nicht mehr außerhalb der Einlagekanten, sondern unmittelbar innerhalb der Kanten. The advantages offered by the innovation are: that it is now possible to remove the welding edge that would otherwise remain on the outside of the deposits to avoid and instead weld the edges around the inlays in such a way that that the plastic film is placed around the edges of the insert. The weld is therefore no longer outside the insert edges, but directly inside the edges.
Durch die Verwendung von Einlagen mit Metallschicht wird es zugleich möglich, saubere und einwandfreie Blind-, Zier- oder Goldprägungen ohne Schwierigkeit auf die fertigen Artikel aufzubringen. By using inserts with a metal layer, it becomes at the same time possible, clean and flawless blind, decorative or gold embossing without difficulty to apply to the finished article.
Die Metallschicht kann auf die Einlage beispielsweise aufgespritzt sein. Man kann aber auch so vorgehen, daß man eine Metallfolie mit einseitiger Papierbeklebung verwendet, wie sie für Verpakkungszwecke benutzt wird. Diese Folie wird mit der Metallseite auf die Einlage geklebt, so daß die Papierseite auf die Außenseite der Einlage zu liegen kommt. Hierdurch wird die Durchschlagssicherheit beim Schweißen oder Prägen bedeutend heraufgesetzt. An Stelle der Beklebung mit Metallfolie könnten die Einlagen auch im Spritzverfahren metallisch überzogen und zusätzlich mit einer Papier- oder Lackschicht versehen sein. Infolge indirekter Verbindung des Metallbelages mit der Grundelektrode durch kapazitiven Kondensatoreffekt werden stärkere Verbrennungen bei Durchschlägen vermieden. The metal layer can, for example, be sprayed onto the insert be. But you can also proceed in such a way that you have a metal foil with one-sided paper pasting used as it is used for packaging purposes. This slide comes with the Metal side glued to the inlay so that the paper side is on the outside of the Deposit comes to rest. This increases the breakdown security during welding or embossing significantly increased. Instead of being glued with metal foil the inlays also coated with metal in the spray process and additionally with a Be provided with a paper or lacquer layer. As a result of indirect connection of the metal covering With the base electrode due to the capacitive capacitor effect, there will be more severe burns avoided in case of breakdowns.
Sollen sehr starke Einlagen in Kunststoffolien eingeschweißt werden, auf welche nachher andere Teile aufgeschweißt oder Prägungen aufgepreßt werden, so müssen die Einlagen zwecks Erhöhung der Kondensatorwirkung beiderseits metallisch durch Bekleben oder Spritzen überzogen sein. If very strong inserts are to be welded into plastic films, on which other parts are welded or embossed afterwards, so the deposits must be metallic on both sides in order to increase the capacitor effect be covered by sticking or spraying.
In der Zeichnung ist die Erfindung an einem Beispiel klargemacht. In the drawing, the invention is made clear using an example.
Fig. I zeigt eine Draufsicht auf eine aus Kunststoff mit Versteifungseinlagen bestehende Mappe, wie sie z. B. für Getränke- oder Speisekarten benutzt werden kann; Fig. 2 zeigt einen Querschnitt zu Fig. I; Fig. 3 ist ein Teilquerschnitt, der den Schweiß-und Prägevorgang verdeutlicht. Fig. I shows a plan view of a plastic with stiffening inserts existing folder, such as B. can be used for drinks or menus; Fig. 2 shows a cross section to Fig. I; Fig. 3 is a partial cross-section showing the Welding and stamping process clarified.
Mit S ist die Außenfolie der Mappe, mit 6 die Innenfolie bezeichnet. 7 und 8 sind Versteifungseinlagen aus Pappe. Bei 9, I0, 11, -I2, I3 und 14 sind die Schweißnähte angedeutet, an denen Außen-und Innenfolie miteinander verbunden werden. The outer film of the folder is denoted by S and the inner film is denoted by 6. 7 and 8 are stiffening inserts made of cardboard. At 9, I0, 11, -I2, I3 and 14 are the weld seams indicated where the outer and inner foil are connected to one another will.
Aus Fig. 3 ist in vergrößertem Maßstab ein Stück der Einlage 7 ersichtlich. Diese Einlage ist oben bei 15 und unten bei I6 mit einer Metallauflage versehen. Soll nun die Aufienfolie 5 mit der Innenfolie 6 an der Schweißnaht g verbunden werden, so faltet man die beiden Folien, wie in der Zeichnung veranschaulicht, im Bereiche der Einlage 7 übereinander und fügt die Folien mit der Einlage zwischen die Schweißelektrode I7 und die Gegenelektrode I8 ein, wobei die Metallauflage I6 als Grundelektrode dient. From Fig. 3, a piece of the insert 7 can be seen on an enlarged scale. This insert is provided with a metal pad at the top at 15 and at the bottom at I6. If the mounting film 5 is now to be connected to the inner film 6 at the weld seam g, so you fold the two foils, as illustrated in the drawing, in the area of the insert 7 on top of one another and inserts the foils with the insert between the welding electrode I7 and the counter electrode I8, with the metal coating I6 as the base electrode serves.
Will man andererseits die Außenseite der Folie 5 mit einer Prägung 19 versehen, so geschieht dies analog dem Schweißvorgang mit Hilfe der Prägeelektrode 20 und der Gegenelektrode 2I, während die Metallauflage 15 wiederum als Grundelektrode dient. If you want, on the other hand, the outside of the film 5 with an embossing 19 provided, this is done analogously to the welding process with the help of the embossing electrode 20 and the counter electrode 2I, while the metal coating 15 is again used as a base electrode serves.
