Description

Verfahren zur Herstellung eines Antriebsbandes oder Förderbandes und Vorrichtung zur Durchführung des Verfahrens Die Erfindung geht aus von einem Verfahren zur Herstellung eines Antriebsbandes oder Förderbandes, wobei mehrere Schichten, die mit Thermoplasten überzogen sind, zu einem Band vereinigt werden und wobei ferner die Einzelbänder zunächst von einer Vorratsrolle abgezogen werden.Process for the production of a drive belt or conveyor belt and Device for carrying out the method The invention is based on a method for the production of a drive belt or conveyor belt, whereby several layers, which are covered with thermoplastics are combined to form a tape and furthermore the individual tapes are first pulled from a supply roll.

Die Aufgabe der Erfindung besteht demgegenüber darin, Verfahren der in Frage stehenden Art insoweit zu verbessern, daß auf einfache Weise Bänder entstehen, die hohe physikalische Eigenschaften, kombiniert mit geringem Gewicht und sauberen Arbeitsbedingungen, aufweisen. In contrast, the object of the invention is to provide the method of to improve the type in question to the extent that ribbons are produced in a simple manner, the high physical properties combined with light weight and clean Working conditions.

Zur Lösung dieser Aufgabe ist bei der Erfindung vorgesehen, daß die Lagen oder Schichten eines synthetischen Filmes oder eines Gewebes mit einem Polyurethanelastomer oder zelligem Polyurethan überzogen oder imprägniert werden, wobei das Polyurethanelastomer und das Polyisozyanat in verschiedenen Kesseln aufbewahrt und unter Druck gemischt zur Auftragung in Form eines Sprays oder in flüssiger Form auf den Film oder das Gewebe aufgebracht werden, wobei ferner alle Schichtbänder von derselben Vorratsrolle abgezogen werden, nach dem Auftragen des Überzuges oder der Imprägnierung über zwei Umlenkrollen zur endlosen Bandbildung geführt werden, wobei sie zwischen den Umlenkrollen durch paarweise angeordnete Preßrollen geführt werden. To solve this problem, the invention provides that the Layers or layers of a synthetic film or fabric with a polyurethane elastomer or cellular polyurethane coated or impregnated, the polyurethane elastomer and the polyisocyanate is stored in different kettles and mixed under pressure for application in the form of a spray or in liquid form to the film or the Tissue are applied, furthermore all layer tapes from the same supply roll peeled off after applying the coating or impregnation over two Deflection rollers are guided for endless belt formation, with them between the deflection rollers are guided by pressing rollers arranged in pairs.

Bei dieser Aufgabenlösung sind folgende an sich bekannte Verfahrensschritte benutzt worden: Es ist bei dem eingangs genannten bekannten Verfahren bekanntgeworden, Gewebebahnen mit Deckschichten aus Thermoplasten zu versehen. In solving this problem, the following process steps are known per se has been used: It has become known in the known method mentioned at the beginning, To provide fabric sheets with cover layers made of thermoplastics.

Es ist fernerhin ein Verfahren zur Herstellung von Treibriemen aus Kunststoff bekanntgeworden, wobei aus Kunststoff bestehende Bänder, die Gewebe und auch filmartige Bänder sein können, so hergestellt werden, daß die Vereinigung der Bänder unter Druck geschieht. It is also a method of manufacturing power transmission belts from Plastic has become known, with ribbons made of plastic, the tissue and film-like tapes can also be produced in such a way that the union of the Tapes happens under pressure.

Es ist fernerhin bekanntgeworden, Polyurethanschaumstoff im Düsenverfahren zu bilden, wobei zweierlei Elemente zugeführt werden und bei der Verdüsung unter Wärme vereinigt werden. It has also become known, polyurethane foam in the nozzle process to form, two types of elements are supplied and under the atomization Warmth to be united.

Es ist darüber hinaus bei der Herstellung eines Riemens bekanntgeworden, einen Träger mit einer Schicht zu besprühen, welche Schicht aus Kohlenstoffstaub besteht. It has also become known in the production of a belt, spraying a substrate with a layer, which layer is made of carbon dust consists.

Es ist außerdem bei mehrlagigen Gewebebändern bekanntgeworden, diese zu imprägnieren. It has also become known in the case of multi-layer fabric tapes, these to impregnate.

Schließlich ist es bei der Herstellung von aus mehreren Filmlagen bestehenden Bändern bekanntgeworden, die Vereinigung der Bänder durch Druckrollen vorzunehmen. After all, it is in the production of multiple layers of film existing belts became known, the union of the belts by pressure rollers to undertake.

Durch die Erfindung wird auf einfache Weise eine einfache Herstellung eines Bandes erreicht, das hohe physikalische Eigenschaften, kombiniert mit geringem Gewicht und sauberen Arbeitsbedingungen, aufweist. Bei der Herstellung wird insbesondere in geschickter Weise von der Tatsache Gebrauch gemacht, daß die Polyurethanbeschichtung es ermöglicht, im noch warmen Zustand die einzelnen Bänder zusammenzupressen, so daß auf Grund des entsprechenden Aggregatzustandes eine einfache Vereinigung der einzelnen Lagen erreicht wird. The invention enables simple manufacture in a simple manner of a tape that combines high physical properties with low Weight and clean working conditions. In the production is in particular cleverly made use of the fact that the polyurethane coating it enables the individual bands to be pressed together while they are still warm, see above that due to the corresponding state of aggregation a simple union of the individual layers is achieved.

Die Erfindung wird an Hand eines Ausführungsbeispieles näher erläutert. Hierbei zeigt F i g. 1 eine Ausführungsform einer Vorrichtung zur Herstellung der Bänder, F i g. 2 eine andere Ausführungsform der Vorrichtung zur Herstellung der Bänder. The invention is explained in more detail using an exemplary embodiment. Here, FIG. 1 shows an embodiment of an apparatus for producing the Tapes, fig. 2 shows another embodiment of the device for producing the Tapes.

Aus der Zeichnung ist das Verfahren zur Herstellung eines Antriebsbandes oder Förderbandes 1 zu erkennen. Mehrere Schichten, die mit Thermoplasten überzogen sind, werden zu einem Band vereinigt. Die Einzelbänder werden zunächst von einer Vorratsrolle 2 abgezogen. From the drawing is the method for producing a drive belt or conveyor belt 1 to be recognized. Several layers covered with thermoplastic are united into a band. The individual bands are first of all from a Supply roll 2 withdrawn.

Die Lagen oder Schichten eines synthetischen Filmes oder Gewebes werden mit einem Polyurethanelastomer oder zelligem Polyurethan überzogen oder imprägniert. Hierbei werden das Polyurethanelasto- mer und das Polyisozyanat in verschiedenen Kesseln aufbewahrt und unter Druck gemischt und in Form eines Sprays 3 oder in flüssiger Form auf den Film oder das Gewebe 4 aufgetragen. Alle Schichtbänder werden von derselben Vorratsrolle 2 abgezogen, nach dem Auftragen des Überzuges oder der Imprägnierung über zwei Umlenkrollen 5, 8 zur endlosen Bandbildung geführt, wobei sie zwischen den Umlenkrollen 5, 8 durch paarweise angeordnete Preßrollen 6,7 geführt werden. Der Abstand zwischen den Umlenkrollen 5,8 ist, entsprechend der Länge des endlosen Bandes 1, veränderbar. The layers or layers of a synthetic film or fabric are coated or impregnated with a polyurethane elastomer or cellular polyurethane. Here the polyurethane elastomer mer and the polyisocyanate stored in different kettles and mixed under pressure and in the form of a spray 3 or applied to the film or fabric 4 in liquid form. All layer tapes are withdrawn from the same supply roll 2 after the coating has been applied or the impregnation via two pulleys 5, 8 to form the endless band, being between the deflection rollers 5, 8 by pressing rollers arranged in pairs 6.7. The distance between the pulleys is 5.8 accordingly the length of the endless belt 1, changeable.
