Verfahren zur überlappenden Klebeverbindung von SchichtenProcess for the overlapping adhesive connection of layers

Die Erfindung betrifft ein Verfahren zur überlappenden Klebeverbindung von Schichten aus natürlichem oder synthetischem Kautschuk- oder Plastikmaterial, bei dem ein Klebemittel auf mindestens eine der zu verbindenden Flächen aufgebracht und diese nach Aneinanderlegen an der gebildeten KLebenaht zusammengedrückt werden.The invention relates to a method for the overlapping adhesive connection of layers of natural or synthetic Rubber or plastic material in which an adhesive is applied to at least one of the surfaces to be joined applied and these are pressed together after placing them next to one another at the K-joint seam formed.

Bei einem bekannten Verfahren dieser Art wird ein Kontaktklebemittel auf die zu verbindenden Flächen aufgebracht und eine KLebenaht dadurch gebildet, daß beide Flächen aneinandergelegt werden. Danach werden die Flächen für eine ziemlich lange Zeit von beispielsweise 20 Minuten zwischen die Platten einer Presse gebracht. Dieses Verfahren erfordert eine schrittweise Bewegung der KLebenaht durch die Platten hindurch, so daß Herstellungs- und Zeitaufwand insbesondere dann verursacht werden, wenn vergleichsweise große und schwere Schichten miteinander zu verbinden sind.In one known method of this type, a contact adhesive is used applied to the surfaces to be connected and a Klebeneam is formed by the fact that both Surfaces are placed next to each other. After that the surfaces placed between the platens of a press for a fairly long time, say 20 minutes. This process requires a step-by-step movement of the joint seam through the panels, so that manufacturing and expenditure of time are caused in particular when comparatively large and heavy shifts are to be connected to each other.

Die Aufgabe der Erfindung besteht darin, ein Verfahren anzugeben, das diese Nachteile vermeidet und auch dieThe object of the invention is to provide a method that avoids these disadvantages and also the

309839/0831309839/0831

Verbindung schwerer und großer Schichten bei einfacherem Verfahrensablauf und geringerem Zeitaufwand ermöglicht.Connection of heavy and large layers with a simpler process sequence and less time required.

Ein Verfahren der eingangs genannten Art ist zur Lösung dieser Aufgabe erfindungsgemäß derart ausgebildet, daß das Zusammendrücken mittels einer vibrierenden Preßwalze erfolgt, die über die Klebenaht geführt wird.A method of the type mentioned is designed according to the invention to achieve this object in such a way that the compression takes place by means of a vibrating press roller, which is guided over the adhesive seam.

Vorzugsweise wird als Klebemittel ein druckabhängiges Klebemittel verwendet.A pressure-dependent adhesive is preferably used as the adhesive.

Mindestens eine Kante der Klebenaht kann durch einen Streifen des die Schichten bildenden Materials abgedeckt werden, dadurch wird die Klebenaht nach außen hin abgedichtet. Eine andere Weiterbildung des Verfahrens kann derart vorgesehen sein, daß jeder zur Abdeckung verwendete Streifen auf seiner einen Seite mit einer der KLebenahtkante angepaßten Abstufung, auf seiner anderen Seite mit einer glatten Kontur versehen ist.At least one edge of the adhesive seam can be covered by a strip of the material forming the layers the adhesive seam is sealed to the outside. Another further development of the process can be be provided in such a way that each strip used for covering on one side with one of the Klebenahtkante adapted gradation, is provided on its other side with a smooth contour.

Die Erfindung umfaßt ferner nach dem Klebeverfahren hergestellte Gegenstände, die zumindest eine überlappende Klebenaht aufweisen. Besondere Vorteile sind mit der Erfindung bei der Herstellung aufblasbarer Röhren erzielbar, die beispielsweise bei der Erzeugung von Hohlräumen in Beton verwendet werden.The invention further comprises articles produced by the gluing process which have at least one overlapping Have glue seam. Particular advantages can be achieved with the invention in the manufacture of inflatable tubes, which are used, for example, in the creation of cavities in concrete.

Im folgenden werden zwei Ausführungsbeispiele der Erfindung anhand der Figuren beschrieben. Es zeigen:In the following two exemplary embodiments of the invention are described with reference to the figures. Show it:

Fig. 1 zwei Schichten aus verstärktem Polychloropren, die nach der Erfindung miteinander zu verbinden sind,Fig. 1 shows two layers of reinforced polychloroprene to be joined together according to the invention are,

Fig. 2 die beiden miteinander verbundenen Schichten,Fig. 2 the two interconnected layers,

309839/0831309839/0831

die mit Streifen aus Neopren zur Abdichtung der Klebenentkanten versehen sind, undwhich are provided with strips of neoprene to seal the adhesive edges, and

Fig. 3 ein weiteres Ausführungsbeispiel einer nach der Erfindung hergestellten Klebeverbindung.3 shows a further exemplary embodiment of an adhesive connection produced according to the invention.

In Fig. 1 sind zwei Schichten aus Polychloropren 1 und 2 mit ca. 3 mm Dicke dargestellt, die mit inneren Verstärkungen 8 versehen sind, welche beispielsweise die Form eines Geflechts haben können. Die Schichten 1 und 2 sind derart nebeneinander angeordnet, daß die untere Fläche der Schicht 1 über der oberen Fläche der Schicht 2 um einen Betrag von ca. ?,5 cm überlappend liegt. Die SchichtIn Fig. 1, two layers of polychloroprene 1 and 2 are shown approximately 3 mm thick, those with internal reinforcements 8 are provided, which can be in the form of a braid, for example. Layers 1 and 2 are juxtaposed such that the lower surface of layer 1 is above the upper surface of layer 2 µm an amount of approx.?, 5 cm overlapping. The layer

1 kann dann zurückgebogen v/erden, und es wird ein Kleberand von ca. 10 cm Breite auf der oberen Fläche der Schicht1 can then be bent back and there will be an adhesive edge approximately 10 cm wide on the top surface of the layer

2 und ein ähnlicher Kleberand von ca. 10 cm Breite auf der unteren Fläche der Schicht 1 gebildet, indem beide Schichten mit einer Drahtbürste behandelt werden. Die so behandelten Flächen werden dann mit einem geeigneten Reinigungsmittel gereinigt, wonach eine Schicht eines vorzugsweise druckabhängigen Klebemittels 3 aufgebracht und getrocknet wird. Eine zweite Schicht des Klebemittels wird über der ersten gebildeten Klebemittelschicht aufgebracht, dann wird die Schicht 1 wieder nach vorn gelegt, so daß beide Schichten 1 und 2 an den Klebemittelschichten miteinander in Berührung kommen. Die so gebildete Klebenaht 5 wird von Hand gedrückt und auf richtige Ausrichtung geprüft. Danach wird eine vibrierende Preßwalze, wie sie beispielsweise in der Bauindustrie zum Walzen von Boden verwendet wird, über die Klebenaht geführt.2 and a similar adhesive edge about 10 cm wide on the lower surface of layer 1 formed by removing both layers treated with a wire brush. The surfaces treated in this way are then cleaned with a suitable cleaning agent cleaned, after which a layer of a preferably pressure-dependent adhesive 3 is applied and dried will. A second layer of adhesive is applied over the first layer of adhesive formed, then Layer 1 is placed forward again so that both layers 1 and 2 are attached to the adhesive layers together come into contact. The adhesive seam 5 formed in this way is pressed by hand and checked for correct alignment. Then a vibrating press roll, such as those used in the construction industry for rolling soil, is used is passed over the adhesive seam.

Beide Seiten der so gebildeten Klebeverbindung werden vorzugsweise mit Streifen zur Abdichtung der Klebenahtkanten versehen. Wie aus Fig. 2 hervorgeht, ist die Klebenaht mit zwei Streifen 4· und 6 aus Neopren versehen, die eine BreiteBoth sides of the adhesive bond so formed are preferred with strips to seal the adhesive seam edges Mistake. As can be seen from Fig. 2, the adhesive seam is provided with two strips 4 · and 6 made of neoprene, which are one width

309839/0831309839/0831

von ca. 6,7 nun haben. Um zu gewährleisten, daß der jeweilige Streifen 4 fest mit den Schichten 1 und 2 verbunden ist, werden die miteinander zu verbindenden Flächen mit einer Drahtbürste vorbehandelt und'dann mit einem Reinigungsmittel gereinigt. Eine Schicht aus druckabhängigem Klebemittel wird auf die vorbehandelten Flächen aufgebracht und abgetrocknet. Eine weitere Schicht des Klebemittels wird dann auf die vorbehandelten Flächen aufgebracht, und der Streifen 4· wird dann mittels einer Handwalze (nicht dargestellt) an der vorgegebenen Stelle befestigt. Eine vibrierende Preßwalze wird dann über den Streifen 4 abgerollt, um ein gutes Anhaften zwischen dem Streifen 4 und den Schichten 1 und 2 zu gewährleisten.of about 6.7 now have. To ensure that the respective Strip 4 is firmly connected to layers 1 and 2, the surfaces to be connected to each other are with pretreated with a wire brush and then with a cleaning agent cleaned. A layer of pressure sensitive adhesive is applied to the pretreated surfaces and dried off. Another layer of the adhesive is then applied to the pretreated surfaces, and the strip 4 · is then by means of a hand roller (not shown) attached to the specified location. A vibrating press roll is then over the Strip 4 unrolled to ensure good adhesion between strip 4 and layers 1 and 2.

Die Schichten 1 und 2 werden dann umgelegt, wonach das beschriebene Verfahren zum Aufbringen des Streifens 6 wiederholt werden kann.The layers 1 and 2 are then turned over, after which the method described for applying the strip 6 can be repeated.

Das vorstehend beschriebene Klebeverfahren kann mit besonderem Vorteil bei der Herstellung aufblasbarer Rohre angewendet werden, die zur Erzeugung von Hohlräumen in Beton oder anderem gießfähigem Material eingesetzt werden. Bei solchen Anwendungsfällen soll die Außenfläche des Rohrs möglichst glatt sein. Wie aus Fig. 2 hervorgeht, bildet die Klebenaht eine Stufe, die auf der Außenfläche eines solchen Formungsrohrs unerwünscht sein kann. Um dieee Schwierigkeit zu vermeiden, kann ein Füllmaterial aus nicht gehärteter Neoprenmasse in die Abstufung der Klebenaht eingepreßt werden, wozu ein spezielles Spritzwerkzeug verwendet werden kann. Hierdurch wird ein glatter Obergang vor dem Aufbringen des Streifens 4 bzw. 6 gebildet. Alternativ kann aber auch gemäß Fig. 3 ein besonders geformter Streifen 10 verwendet werden, der auf seiner einen Seite mit einer Abstufung 12 versehenThe gluing process described above can be of particular advantage in the manufacture of inflatable tubes used to create cavities in concrete or other pourable material. In such applications, the outer surface should of the pipe should be as smooth as possible. As can be seen from Fig. 2, the adhesive seam forms a step on the outer surface such a forming tube may be undesirable. To avoid the problem, a filler material made of non-hardened neoprene mass in the gradation of Glued seam can be pressed in, for which purpose a special injection molding tool can be used. This will make a smoother Transition formed before the application of the strip 4 or 6. Alternatively, however, according to FIG. 3, a specially shaped strip 10 can be used, which is provided with a step 12 on one side

309839/0831309839/0831

ist, die der Abstufung der Klebenaht angepaßt ist. Auf der anderen Seite ist der Streifen 12 mit einer glatten Oberfläche versehen, seine Kanten laufen durch entsprechende Abschrägung oder Abrundung spitz zu.which is adapted to the gradation of the adhesive seam. On the other hand, the strip 12 is smooth with a Surface provided, its edges are tapered by appropriate bevelling or rounding.

Es hat sich gezeigt, daß die Andruckzeit für zwei PoIychloroprenschichten von ca. 3 nun Dicke bei einer Klebenaht von ca. 23 m Länge und einer Überlappung von ca. 7,5 cm ungefähr 10 Minuten beträgt, wenn eine vibrierende Preßwalze mit einem Verdichtungsfaktor von ca. 2 t verwendet wird.It has been shown that the pressure time for two polychloroprene layers of approx. 3 now thickness with a glued seam of approx. 23 m length and an overlap of approx. 7.5 cm is approximately 10 minutes if a vibrating press roll with a compression factor of approx. 2 tons is used.
