Description
"Verfahren zur Vereinigung von Blättern oder Taschen* Die durchsichtigen Blätter oder Taschen, welche in einen Einband eingesetzt werden sollen, welcher auf der Innenseite seines Rückens metallische Halter aufweist, in welche die Enden von Metallstäben treten, müssen an diesen Stäben befestigt werden. Diese Befestigung erfolgt im allgemeinen entsprechend dem Werkstoff dieser Blätter oder Taschen durch Hochfrequenzsiegelung, Kleben oder Stiche."Method of joining sheets or pockets * The transparent ones Sheets or pockets to be inserted into a cover, which has metallic holders on the inside of its back into which the ends step from metal rods must be attached to these rods. This attachment is generally carried out according to the material of these sheets or pockets High frequency sealing, gluing, or stitches.
Mehrere Blätter oder Taschen können zwar an dem gleichen Stab durch Kleben oder Stiche leicht befestigt werden, dagegen ist es sehr schwierig, sie durch flache Siegelung zu vereinigen, insbesondere wenn sie aus Polyäthylen oder dergleichen bestehen. Da ferner das Polyäthylen oder ähnliche Werkstoffe bei Zufuhr einer großen Wärmemenge eine geringe Maßhaltigkeit haben, tritt nach der Siegelung ein so großer Schwund auf, daß die vereinigten Teile verformt und unbrauchbar gemacht werden. Dieser Nachteil begrenzt die Anwendung von durchsichtigen Blättern oder Taschen aus den genannten biegsamen Kunststoffen beträchtlich.Multiple sheets or bags can go through on the same stick Gluing or stitches can be easily attached, however It very difficult to unite them by shallow seals, especially if they are made of polyethylene or the like exist. As also the polyethylene or similar materials Supply of a large amount of heat will have poor dimensional accuracy, occurs after the Sealing resulted in such a large loss that the united parts deformed and become unusable be made. This disadvantage limits the use of clear sheets or bags made of said flexible plastics considerably.
Die Erfindung bezweckt, diesem Nachteil abzuhelfen. Hierfür hat sie ein Verfahren zur Vereinigung von Blättern oder Taschen aus Polyäthylen oder ähnlichen Werkstoffen zum Gegenstand, welches darin besteht, die Ränder einer gewissen Zahl derartiger Blätter oder Taschen unter Einschluss eines Metallstabes mittels einer Apparatur zu vereinigen, welche die zum Schmelzen des Werkstoffes erforderliche Wärme auf genau bestimmte Weise ausgibt und nach der Siegelung einen Kaltdruck liefert, welcher den Zusammenhalt des Werkstoffes um den Stab herum bewirkt, dessen Enden aus dem so erhaltenen Bündel dberstehen, so daß er später in einen entsprechenden Einband eingesetzt werden kann.The invention aims to remedy this disadvantage. For this she has a method of joining sheets or bags made of polyethylene or the like Materials to the object, which consists in the edges of a certain number such sheets or bags including a metal rod by means of a To combine apparatus, which is necessary for melting the material Emits heat in a precisely defined way and provides a cold pressure after sealing, which causes the cohesion of the material around the rod, its ends protrude from the bundle thus obtained, so that it can later be transferred to a corresponding Binding can be used.
Dieses Vereinigungsverfahren bietet den Vorteil, die Befestigung des Werkstoffes an den Stab zu erzwingen, welcher so die Bewehrung des Bündels bildet und jede spätere Schrumpfung des Werkstoffes verhindert, welche Falten oder dergleichen erzeugt, welche den Artikel infolge mangelnder Formschönheit unbrauchbar machen.This merging process has the advantage of making the attachment of the To force the material to the rod, which so the Reinforcement of the Bundles and prevents any subsequent shrinkage of the material, which wrinkles or the like, which makes the article unusable due to a lack of aesthetics do.
Ferner besitzt das so erhaltene Bündel den Vorteil, eine sehr geringe Dicke bei einer sehr großen Aufnahmefähigkeit zu haben, so daß das Fassungsvermögen des derartigen Bündel enthaltenden Einbands beträchtlich vergrößert werden kann, was noch den zusätzlichen Vorteil ergibt, eine Tasche zu ergeben, welche praktisch die gleiche Abmessung wie das zu schützende Dokument hat.Furthermore, the bundle thus obtained has the advantage of being very small Thickness to have a very large capacity, so that the capacity the binding containing such bundles can be enlarged considerably, which gives the added benefit of making a bag that is practical has the same dimensions as the document to be protected.
Die Enden des Stabes sind natürlich entsprechend dem vorgesehenen Einband geformt. Sie können gerade, gekrümmt oder vollständig gebogen sein.The ends of the rod are of course in accordance with the intended Shaped cover. They can be straight, curved, or fully curved.
Die Erfindung ist nachstehend unter Bezugnahme auf die Zeichnung beispielshalber erläutert.The invention is described below by way of example with reference to the drawing explained.
Fig. 1 ist eine Draufsicht einer erfindungsgemäßen Anordnung.Fig. 1 is a top plan view of an arrangement according to the invention.
Fig. 2 ist ein Schnitt längs der Linie 2-2 der Fig. 1 in größerem Maßstab.Fig. 2 is a larger section taken along line 2-2 of Fig. 1 Scale.
Bei der dargestellten Ausführung stellt 2 durchsichtige Taschen aus einem heißsiegelfähigen Kunststoff, insbesondere Polyäthylen, dar.In the embodiment shown, two clear pockets are exhibited a heat-sealable plastic, especially polyethylene.
Erfindungsgemäß erfolgt die Vereinigung der Ränder 3 mehrerer derartiger Taschen durch Siegelung nach Anbringung eines Metallstabes 4 zwischen den Rändern 3, dessen Länge etwas größer als die Höhe der Taschen ist. Die Siegelung erfolgt mittels einer Apparatur, welche die für das Schmelzen des Werkstoffes erforderliche Wärme in der bei 5 in Fig. 2 dargestellten Siegelzone erzeugt, d.h. beiderseits des Stabes 4.According to the invention, the merging of the edges 3 of several of these takes place Bags by sealing after attaching a metal rod 4 between the edges 3, the length of which is slightly greater than the height of the bags. The seal takes place by means of an apparatus which is necessary for melting the material Heat generated in the sealing zone shown at 5 in Fig. 2, i.e. on both sides of the staff 4.
Auf diese Siegelung folgt ein Kaltpressen, welches ein gutes Haften des Werkstoffes in der Siegelzone 5 bewirkt und die Befestigung desselben an dem Stab 4 erzwingt, welcher so die Bewehrung der Anordnung bildet und jedes spätere Schrumpfen des die Blätter bildenden Werkstoffes verhindert.This sealing is followed by cold pressing, which has good adhesion causes the material in the sealing zone 5 and the attachment of the same to the Forces rod 4, which forms the reinforcement of the arrangement and each subsequent one Prevents shrinkage of the material forming the sheets.
Die Taschen 2 sind so fest miteinander verbunden und bilden ein Bündel, welches, wie in Fig. 2 gezeigt, eine sehr geringe Dicke hat, Aus diesem Bündel stehen die beiden Enden des Stabes 4 vor, welche für seine Befestigung an einem Einband dienen, welcher metallische Halter aufweist, in welche diese Enden eingeführt werden.The pockets 2 are firmly connected to each other and form a bundle, which, as shown in Fig. 2, has a very small thickness, stand out from this bundle the two ends of the rod 4 in front, which are used for its attachment to a binding serve, which has metallic holders into which these ends are inserted.
Die Enden des Stabes können natürlich entsprechend der Befestigungsart an dem Einband gerade sein, wie-bei dem dargestellten Ausführungsbeispiel, oder geknickt oder vollständig gebogen.The ends of the rod can of course, depending on the type of attachment be straight on the cover, as-in the illustrated embodiment, or kinked or completely bent.
