Vorrichtung zum Verbinden von flachen GegenständenDevice for connecting flat objects

Die Erfindung betrifft eine Vorrichtung zum Verbinden von flachen Gegenständen, insbesondere zum Aneinanderkleben derEnden von zwei Riemen oder eines Riemens, um diesen endlos zu machen, bei der zwei Platten auf beiden Seiten der Verbindungsstelle der Riemen od. dgl. angeordnet sind, eine Traversenanordnung auf der Außenseite wenigstens einer Platten vorgesehen ist und die Traversen durch Stangen od. dgl. mit der anderen Platte zu verbinden sind, wobei ferner eine druckmittelbetätigte Einrichtung, die sich gegen die Traversen abstützt, vorgesehen ist, um auf die zugehörige Platte eine Schließkraft in Richtung auf die andere Platte auszuüben. The invention relates to a device for connecting flat objects, in particular for gluing them together the ends of two belts or a belt to make it endless, with two plates on either side of the Connection point of the belt or the like. Are arranged, a truss arrangement on the outside of at least one plate is provided and the traverses od by rods. Like. To be connected to the other plate, furthermore a pressure medium-operated device, which is supported against the crossbars, is provided to the associated plate exert a closing force in the direction of the other plate.

Zur Ausübung der Schließkraft ist bei Vorrichtungen dieser Art ein durch ein Druckmittel aufblasbares Kissen vorgesehen, das sich gegen die Traversen abstützt. Diese Anordnung hat den Nachteil, daß eine zusätzliche Platte zwischen dem Kissen und den Traversen vorgesehen werden muß, damit das Kissen beim. Aufblasen nicht in die ZwischenräumeIn devices of this type, a cushion that can be inflated by a pressure medium is used to exert the closing force provided that is supported against the crossbars. This arrangement has the disadvantage that an additional plate must be provided between the cushion and the trusses so that the cushion during. Do not inflate into the gaps

zwischen den aufeinanderfolgenden Traversen eindringt und zerplatzt. Ferner müssen seitliche Haltemittel vorgesehen werden, damit das Kissen auch nicht am Umfang des Raumes herausplatzt, der zwischen der Hauptplatte und der zusätzlichen Platte vorhanden ist. Es ergibt sich damit eine verhältnismäßig teuere Konstruktion.penetrates between the successive trusses and bursts. Lateral holding means must also be provided so that the pillow does not pop out at the perimeter of the space between the main plate and the additional Plate is present. This results in a relatively expensive construction.

Der Erfindung liegt die Aufgabe zugrunde, eine solche Vorrichtung mit druckmittelbet/iätigter Einrichtung zur Erzeugung der Schließkraft erheblich zu vereinfachen.The invention is based on the object of providing such a device with a pressure medium-actuated device To simplify the generation of the closing force considerably.

Diese Aufgabe wird erfindungsgemäß mit einer Vorrichtung der eingangs genannten Art dadurch gelöst, daß die Traversen einen Querschnitt in Form einer Rinne aufweisen, die zur zugehörigen Platte hin offen ist und einen aufblasbaren Schlauch enthält.This object is achieved according to the invention with a device of the type mentioned in that the traverses have a cross section in the form of a channel which is open to the associated plate and a Includes inflatable tube.

Eine solche Vorrichtung erfordert keinen besonderen Aufwand in Form von Platten usw. für das Umschließen der Schläuche. Sofern die Rinnen genügend dicht beieinander liegen, wird eine im wesentlichen gleichmäßige Schließkraft auf der ganzen Fläche der Platten erhalten.Such a device does not require any special effort in the form of plates, etc. for enclosing the Hoses. If the grooves are sufficiently close together, an essentially uniform closing force is achieved Preserved over the entire surface of the panels.

Zu bemerken ist, daß bei einer solchen Vorrichtung, sobald die Schläuche begonnen haben, die Platte vorzudrükken, zwischen dieser und den Traversen spaltförmige Räume von schwacher Höhe entstehen. In diesem Bereich sind die Schläuche nicht mehr durch feste Wände gehalten, und es besteht die Gefahr, daß sieh die Schläuche hier übermäßig ausdehnen. Diesem Umstand kann jedoch sehr leicht dadurch begegnet werden, daß die Schläuche genügend widerstandsfähig ausgebildet werden, so daß sie aus den engen Spalten nicht herausplatzen können» Die Schläuche können insbesondere mit einem Verstärkungsgewebe versehen werden.It should be noted that with such a device, as soon as the tubes have started to advance the plate, between this and the traverses, gap-shaped spaces of low height arise. In this area are the Hoses are no longer held by solid walls and there is a risk that the hoses will look excessive here expand. This fact can, however, be counteracted very easily by making the hoses sufficiently resistant be designed so that they cannot burst out of the narrow gaps »The hoses in particular can be provided with a reinforcement fabric.

Die dargestellte Vorrichtung enthält zwei Platten 1,2 beliebiger Art, die elektrisch oder mittels Dampf usw. beheizt werden können, wobei die Temperatur in beliebiger Weise regelbar ist. Zwischen den Platten 1 und 2 werden die zu verbindenden Gegenstände angeordnet. Hier ist angenommen, daß die beiden Enden 3, 4 eines Riemens zu verbinden sind, die entsprechend abgeschrägt und mit Klebestoff versehen sind.The device shown contains two plates 1, 2 of any type, which are heated electrically or by means of steam, etc. can be, the temperature can be regulated in any way. Between the plates 1 and 2 are the connecting objects arranged. Here it is assumed that the two ends 3, 4 of a belt are to be connected, which are bevelled accordingly and provided with adhesive.

Jeder Platte 1,2 ist eine Traversenanordnung zugeordnet, die aus einer Anzahl von Traversen 5 (beim dargestellten Beispiel drei Traversen) besteht, die über die Länge der Platten gleichmäßig verteilt sind. Jede Traverse ist aus zwei U-Eisen 6 zusammengesetzt, die mit dem Rücken einander zugekehrt in einer bestimmten Entfernung liegen und miteinander durch ein horizontales, angeschweißtes Stegblech verbunden sind. Das Stegblech 7 ist etwa in der mittleren Höhe der U-Eisen 6 angebracht, so daß die ganze Traverse einen H-förmigen Querschnitt hat, und endet mit einem bestimmten Abstand vor den Enden der U-Eisen 6. Ferner ist die Länge der Traversen 5 größer als die Breite der Platten 1,2, so daß die Enden der Traversen 5 seitlich über die beiden Platten 1, 2 hinausragen. Jede Traverse 5 der oberen fi£2&x-SjraSrae xst senkrecht gesehen auf die entsprechende Traverse 5 der unteren Traversenanordnung ausgerichtet, und die beiden entsprechenden Traversen 5 der beiden Traversenan-Each plate 1, 2 is assigned a truss arrangement, which consists of a number of trusses 5 (when shown Example three traverses), which are evenly distributed over the length of the plates. Every traverse is composed of two U-irons 6, which are with their backs facing each other at a certain distance and are connected to each other by a horizontal, welded web plate. The web plate 7 is approximately in the middle Height of the U-iron 6 attached so that the whole traverse has an H-shaped cross-section, and ends with a certain Distance in front of the ends of the U-irons 6. Furthermore, the length of the crossbars 5 is greater than the width of the plates 1, 2, so that the ends of the crossbars 5 laterally over the two Plates 1, 2 protrude.

Ordnungen sind durch, zwei Stangen 8 verbunden, die durch die Enden der Traversen 5 außerhsfo des Stegblechs 7 hindurchgehen. Die Stangen 8 sind mit Anschlägen versehen, die sich gegen Unterlagscheiben 9> Io legen. Beim dargestellten Ausführungsbeispiel sind die Stangen 8 in Form von langen Schraubenbolzen ausgeführt, die einen Kopf 11 aufweisen, und auf deren Gewindeende eine Mutter 12 aufschraubbar ist. Selbstverständlich kann irgendeine andere Anordnung vorgesehen werden. Beispielsweise könnten die Unterlagscheiben 9» 1o seitlich geschlitzt sein, so daß ein bequemes Einsetzen der Stangen 8 ohne volles Abschrauben der Muttern 12 möglich ist. Jede Stange 8 könnte auch gelenkig mit einer Traverse 5 verbunden sein und Haken od. dgl. zum Anschluß an die andere Traverse 5 aufweisen usw. Zu bemerken ist noch, daß es zur Erleichterung der Handhabung vorteilhaft ist, die Unterlagscheiben 9» 1o andBn vorgesehenen U-Eisen 6 und die Köpfe 11 an den Unterlagscheiben anzuschweissen. Orders are connected by, two rods 8, which are connected by the Pass the ends of the crossbars 5 outside of the web plate 7. The rods 8 are provided with stops that are against washers 9> Lay Io. In the illustrated embodiment, the rods 8 are in the form of long screw bolts executed, which have a head 11, and on the threaded end of which a nut 12 can be screwed. Of course you can any other arrangement may be provided. For example, the washers 9 »10 could be slotted laterally, so that a comfortable insertion of the rods 8 without completely unscrewing the nuts 12 is possible. Each rod 8 could can also be articulated to a cross member 5 and hooks or the like for connection to the other cross member 5, etc. It should also be noted that, to facilitate handling, it is advantageous to provide the washers 9-10 and Bn U-iron 6 and the heads 11 to be welded to the washers.

In dem rinnenförmigen Raum, der durch die zur Platte oder 2 gerichtete Fläche des Stegblechs 7 jeder Traverse 5 und durch die entsprechenden Flächen der beiden U-Eisen 6 gebildet wird, ist ein dichter Schlauch 13 gelagert, der mittels einer Zuführungsleitung 14 aufblasbar ist. Das benutzte Druckmittel kann ein Gas oder eine Flüssigkeit sein. Der Schlauch 13 ist von bekannter Art und ist mit einem Verstärkungsgewebe versehen, so daß er einen erheblichen Innendruck aushalten kann. Seine Querschnittsfläche ist im aufgeblasenen Zustand größer als die Querschnittsfläche des erwähnten rinnenförmigen Raumes.In the channel-shaped space formed by the surface of the web plate 7 of each traverse 5 directed towards the plate or 2 and is formed by the corresponding surfaces of the two U-irons 6, a tight tube 13 is supported, the is inflatable by means of a supply line 14. The pressure medium used can be a gas or a liquid. The hose 13 is of known type and is provided with a reinforcing fabric provided so that it can withstand a significant internal pressure. Its cross-sectional area is in the inflated State larger than the cross-sectional area of the mentioned channel-shaped space.

Zur Benutzung der vorher auseinandergenommenen Vorrichtung werden die zu verbindenden Riemenenden, nachdem sie mit Klebestoff versehen worden sind, auf die untere Platte 2 aufgelegt. Die beiden Traversenanordnungen werden dann auf und unter den Platten 1,2 angeordnet (die untere Traversenanordnung kann übrigens unter der Platte 2 schon vor dem Auf-To use the previously dismantled device, the belt ends to be connected are after they have been provided with adhesive, placed on the lower plate 2. The two truss assemblies are then on and arranged under the plates 1, 2 (by the way, the lower truss arrangement can be placed under the plate 2 before it is installed.

legen des Riemens angeordnet werden). Die Muttern 12 der Stangen 8 werden dann sehr mäßig angezogen, um die Teile in ihrer Lage zu halten, ohne Jedoch eine wesentliche Druckkraft auf den Riemen auszuüben. Hiernach werden die Schläuche 13 mit gleichem Druck aufgeblasen, so daß sie eine gleichmäßige Schließkraft bzw. Verbindungskraft auf die Platten 1 und 2, jeweils in Richtung von der einen zur anderen Platte, ausüben. Erforderlichenfalls kann dann ein Aufheizen der Platten stattfinden.place the belt). The nuts 12 of the rods 8 are then tightened very gently to the parts in place without, however, exerting any substantial compressive force on the belt. After that the hoses 13 inflated with the same pressure, so that they have a uniform closing force or connecting force on the Exercise plates 1 and 2, each in the direction from one plate to the other. If necessary, heating can then be carried out of the plates take place.

Sobald das Verkleben beendet ist, werden die Schläuche entlüftet und die Vorrichtung wird auseinandergenommen, um den zusammengeklebten Riemen entnehmen zu können.Once the gluing is finished, the hoses are deflated and the device is disassembled in order to to be able to remove the glued-together straps.

Es ist möglich, die Vorrichtung zu vereinfachen, indem nur für die eine Traversenanordnung aufblasbare Schläuche vorgesehen werden, beispielsweise für die obere Anordnung. Ferner kann die untere Anordnung dauernd an der zugehörigen Platte 2 befestigt werden, was die Handhabung erleichtert, insbesondere können die Stangen 8 an dieser unteren Anordnung so angelenkt werden, daß ein Anheben derselben genügt, um sie in die Unterlagescheiben 9 einzurasten, die zu diesem Zweck in entsprechender Weise geschlitzt sind.It is possible to simplify the device by providing inflatable tubes only for the one truss arrangement for example for the upper arrangement. Furthermore, the lower arrangement can be permanently attached to the associated plate 2 be attached, which facilitates handling, in particular the rods 8 can be articulated to this lower arrangement be that a lifting of the same is sufficient to snap them into the washers 9, which for this purpose in the corresponding Way are slotted.
