Description

Verbindung der Enden von Riemen aus gewebtem oder geflochtenem Textilmaterial Die Erfindung betrifft eine Verbindung der Enden von Riemen aus gewebtem oder geflochtenem Textilmaterial, bei dem ein Hilfsverbindungsteil benutzt wird, das mit den stumpf aneinanderstoßenden Enden verklebt wird.Connection of the ends of straps made of woven or braided textile material The invention relates to a connection of the ends of straps made of woven or braided material Textile material in which an auxiliary connecting part is used, which is butted with the butting ends is glued.

Es ist bekannt, Riemen oder Gurte zum Antrieb oder zur Förderung aus natürlichem, synthetischem oder künstlichem Textilmaterial herzustellen. Diese Riemen oder Gurte sind gewebt oder geflochten und werden in sich selbst entweder durch eine Naht, Klammern oder Niete oder auch bereits wie bei dem Eründnngsgegenstand durch Kleben geschlossen. It is known to use belts or belts for propulsion or for conveyance made from natural, synthetic or man-made textile material. These Straps or belts are woven or braided and are either in themselves by a seam, staples or rivets or already as with the object of the invention closed by gluing.

Dieses Kleben erfolgt unter Zuhilfenahme verschie dener Stoffe, insbesondere synthetischer Stoffe auf Superpolyamidbasis, die durch Wärmeeinwirkung schmelzbar sind und entweder in flüssiger Form oder in Form einer festen Haut benutzt werden, wobei das Kleben im allgemeinen nach dem Übereinanderlegen der beiden Enden des Riemens oder Gurtes durch die kombinierte Anwendung von Wärme und Druck erfolgt. Es ist auch bereits eine Verbindung zweier Riemenenden aus Textilmaterial bekannt, bei der ein Filfsverbindnngsteil benutzt wird, das auf die stumpf aneinanderstoßenden Enden aufgelegt und mit ihnen verklebt wird. Bei Venvendung eines derartigenHilfsverbindungsteiles, welches aus einer einfachen Poiyamidhaut besteht, die an sich schon keine mechanische Widerstandsfähigkeit hat und im Augenblick der Verschmelzung sofort verschwindet, ist man benötigt, entweder die beiden äußeren Enden des Riemens überlappt anzuordnen oder ein weiteres zusätzliches Ver-Nndungssfttck vorzusehen. In beiden Fällen wird aber eine von außen merkliche Überstärke erzielt, die sich besonders dann unliebsam bemerkbar macht, wenn ein auf diese Art hergestellter Riemen Scheiben oder Rollen sehr kleinen Durchmessers umwinden muß. This gluing takes place with the help of various substances, in particular synthetic fabrics based on super polyamides that melt when exposed to heat and are used either in liquid form or in the form of a firm skin, the gluing generally after the two ends of the Belt or belt is made by the combined application of heat and pressure. A connection between two belt ends made of textile material is already known, in which a Filfsverbindnngteil is used, which on the butt butted The ends are placed and glued to them. When using such an auxiliary connection part, which consists of a simple polyamide skin, which in itself is not a mechanical one Has resilience and disappears immediately at the moment of merging, it is necessary to arrange either the two outer ends of the belt so as to be overlapped or to provide another additional connection piece. In both cases will but an excess of strength that is noticeable from the outside is achieved, which is particularly unpopular makes noticeable when a belt made in this way is pulleys or pulleys must wind very small diameter.

Diese überstände werden durch die Erfindung be seitigt; sie besteht darin, daß das Hilfsverbindungsteil gewebt oder geflochten und mit Kunststoff überzogen ist, so daß sein Zugwiderstand dem des Rie mens gleich ist, und jeweils einige Zentimeter in die Enden des rohrförmigen Riemens eingeführt ist. Somit ist der wesentliche Vorteil erzielt, daß eine Verbindung der Riemenenden erreicht wird, ohne den wesentlichen Nachteil in Kauf nehmen zu müssen, daß eine merkbare Verdickung der Enden erfolgt. Wie bereits erwähnt, wird beim Anmeldungsgegenstand ein Verbindungsteil verwandt, das ebenso wie der Riemen gewebt oder geflochten ist, also als dünnes gewebtes oder geflochtenes Band bezeichnet werden kann. Dieses Band hat eine sehr große Zugwiderstandskraft und ist mit einem plastischen Überzug versehen, der bei seiner Verschmelzung die innige Verbindung des Riemens mit dem Milfsverbindungsteil herstellt. Selbstverständ- lich besteht die Möglichkeit, dieses Band als normales Webband herzustellen oder auch schlauchförmig zu weben. Der Kunststoffüberzug für das IIilfsverbindungsteil kann entweder durch Aufstreichen oder durch eine aufgebrachte dünne Haut hergestellt werden. Der erfindungsgemäße Riemen hat den wesentlichen Vorteil, daß er dadurch, daß er keine merkliche Überstärke an den Verbindungsstellen aufweist, einen wesentlich ruhigeren Lauf des Antriebes od. dgl. zuläßt, da die Gefahr von Stößen bei jedem Übergang über die Riemenscheibe beseitigt ist. Durch die innige Verbindung der Riemenenden mit dem Hilfsverbindungsteil durch die Verschmelzung des Kunststoffes in diesen Teilen besteht auch keine Gefahr, daß beim Betrieb ein Reißen der Verbindungsstelle erfolgt. These overhangs are eliminated by the invention; she consists in that the auxiliary connecting part is woven or braided and covered with plastic is so that its tensile resistance is the same as that of the mens Rie, and each a few centimeters is inserted into the ends of the tubular belt. Thus the essential Advantage achieved that a connection of the belt ends is achieved without the essential The disadvantage of having to accept that there is a noticeable thickening of the ends. As already mentioned, a connecting part is used in the subject of the application, which, like the belt, is woven or braided, i.e. as a thin woven or braided tape can be called. This tape has a very large tensile strength and is provided with a plastic coating that, when fused, the establishes an intimate connection of the belt with the Milfsconnecting part. Self-evident lich there is the possibility of producing this ribbon as a normal woven ribbon or also to weave tubular. The plastic coating for the auxiliary connection part can produced either by brushing on or by applying a thin skin will. The belt according to the invention has the significant advantage that it that it does not have any noticeable excess thickness at the joints, which is essential Allows smoother running of the drive or the like, since there is a risk of bumps in everyone Transition over the pulley is eliminated. Due to the intimate connection of the belt ends with the auxiliary connecting part by the fusion of the plastic in these There is also no risk of splitting the connection point during operation he follows.

In den Zeichnungen ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigt Fig. 1 die drei Bestandteile der Verbindung eines flachen, schlauchförmigen Riemens, Fig. 2 den Querschnitt des Verbindungsteiles schematisiert, Fig. 3 den in ein Ende des schlauchförmigen Rie mens eingesetzten Rilfsverbindungsteil, Fig. 4 die fertige Verbindung in der Draufsicht, Fig. 5 einen Schnitt durch die fertige Verbindung nach der Linie 5-5 der Fig. 4. In the drawings, an embodiment of the invention is shown. It shows Fig. 1 the three components of the connection of a flat, tubular Belt, Fig. 2 shows the cross section of the connecting part schematically, Fig. 3 shows the auxiliary connection part inserted into one end of the tubular Rie mens, Fig. 4 shows the finished connection in plan view, FIG. 5 shows a section through the finished connection Connection according to line 5-5 of FIG. 4.

Bei Vorliegen eines geflochtenen, schlauchförmigen und abgeplatteten Textilstreifens, der als endloser Riemen oder Gurt benutzt werden soll, wird nach Abschneiden der gewünschten Länge die erfindung gemäße Verbindung wie folgt hergestellt: Ein Band oder eine Tresse 2 von einigen Zentimetern Länge wird als Hilfsverbindungsteil mit einer Haut aus plastischem Kunststoff überzogen (Fig. 2). In the presence of a braided, tubular and flattened one Textile strip that is to be used as an endless belt or belt is after cut off the desired length, the connection according to the invention made as follows: A ribbon or a tress 2 a few centimeters in length is covered as an auxiliary connection part with a skin made of plastic (Fig. 2).

Diese Haut kann z. B. ein Kunststoff aus Superpolyamidbasis sein. Die Breite des Bandes ist etwas kleiner als die des abgeplatteten Textilstreifens. Dieses Hilfe verbindungsteil 2 wird etwa auf die Hälfte seiner Länge in ein Ende 4a des schlauchförmigen Riemens eingeführt (Fig. 3), worauf das restliche Stück des Hilfsverbindungsteiles in das andere Ende 4b des Riemens eingeführt wird, bis die beiden Enden 4 a und 4b des Riemens stumpf gegeneinanderstoßen. Danach wird die Verbindungsstelle einige Sekunden erwärmt, wobei gleichzeitig ein Druck auf sie ausgeiibt wird, was beispielsweise mit einer elektrischen Zange erfolgen kann. Hierauf wird die Verbindungsstelle abge kühlt. Um ein Ausfransen der Schnittkante der beiden Enden 4 a und 4b zu vermeiden, können diese entweder im warmen Zustand abgeschnitten werden, falls der Riemen aus einem selbstschweißenden Werkstoff besteht, oder auch mit einem plastischen Stoff bestrichen werden, der dem Überzug des Hilfsverbindungsteiles 2 entspricht. Dieser Überzug wird bei der Herstellung der Verbindung gleichzeitig mit verschweißt.This skin can e.g. B. be a plastic based on super polyamide. The width of the tape is slightly smaller than that of the flattened textile strip. This help connecting part 2 is about half its length in one end 4a of the tubular belt inserted (Fig. 3), whereupon the remaining piece of the auxiliary connecting part is inserted into the other end 4b of the belt until the two ends 4 a and 4 b of the belt butt against each other. After that, will the joint is heated for a few seconds, while simultaneously applying pressure it is output, which can be done, for example, with electric pliers. The connection point is then cooled down. About fraying of the cut edge To avoid the two ends 4 a and 4 b, these can either be in the warm state be cut off if the belt is made of a self-welding material, or coated with a plastic material, the coating of the auxiliary connecting part 2 corresponds. This coating is used in the Establishing the connection at the same time with welded.

Das Hilfsverbindungsteil 3 kann auch schlauchförmig ausgebildet werden, beispielsweise als schlaucllförmig gewebtes Band. Auch die Abschrägung der Ecken des Hilfsverbindungsteiles zwecks besserer Einführung desselben in den Riemen ist möglich. The auxiliary connecting part 3 can also be designed in the form of a hose, for example as a tubular woven tape. Also the beveling of the corners of the auxiliary connecting part for the purpose of better introduction of the same into the belt possible.
