Verfahren und Vorrichtung zum Verbinden nichtvulkanisierter KautschukfolienMethod and device for joining unvulcanized rubber films

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Verbinden nichtvulkanisierter Kautschukfolien, insbesondere zum Überziehen von Stahlkordeinlagen mit Gummi oder zum Aufbringen von Kappen auf mit Gummi überzogenen Textilkordeinlagen. The invention relates to a method and a device for joining non-vulcanized rubber films, in particular for covering steel cord inserts with rubber or for attaching caps to textile cord inserts covered with rubber.

Bisher ist das Verbinden der beiden Bänder von sogenannten Kappen beim überziehen von Stahlkordeinlagen mit einer Kautschukfolie mit Hilfe von Walzen oder Pressen derart durchgeführt worden, daß ein Ende der einen Folie über den Anfang der zweiten Folie gelegt worden ist. Dabei gewährleistet die Klebrigkeit des nichtvulkaniserten Kautschukgemisches eine dauerhafte Verbindung zwischen den beiden Enden der beiden Kautschukfolien.So far, the connection of the two bands has been so-called caps when covering steel cord inserts with a rubber sheet with the help of rollers or presses has been carried out in such a way that one end of a film over the beginning the second slide has been placed. The stickiness of the non-vulcanized rubber mixture ensures a permanent connection between the two ends of the two rubber foils.

Nachdem die Folien zusammen mit der Stahlkordeinlage zwischen den beiden Walzen einer Presse hindurchgeführt worden ist, bleibt die Verdickung der Gummischicht an der "überlappungsverbindung bestehen, während die Kordeinlage in diesem Bereich einer ungleichmäßigen Verbreiterung unterworfen wird. Diese verdickten Abschnitte können im Hinblick auf die Erfordernisse hinsichtlich der Ausführung von Seifen nicht mit weiterverarbeitet werden. Daher wurde das gesamte Band der mit Gummi überzogenen Stahlkordeinlage zu Einlageteilen zerschnitten, wobei die verdickten Abschnitte abgeschnitten wurden.After the foils together with the steel cord insert have been passed between the two rollers of a press is, the thickening of the rubber layer remains at the "lap joint, while the cord insert remains in this Area is subjected to an uneven widening. These thickened sections can be used in terms of Requirements regarding the execution of soaps are not processed further. Hence the entire tape the rubber-coated steel cord insert cut into insert parts, with the thickened sections being cut off became.

Dieses Verfahren führte zu Materialverlusten des hochwertigen Kautschukgemisches und der teuren Abschnitte der verlöteten Stahlkordeinlage und erforderte einen zusätzlichen Arbeitsschritt, nämlich das Schneiden der Abschnitte. Beim Pressen oder Walzen von Textilkordeinlagen ist es ebenfalls bekannt, Folien mit Überlappung zu verbinden, aber es bestand keine Veranlassung, die Überlappungen zu entfernen.This process led to material losses of the high-quality rubber mixture and the expensive sections of the soldered Steel cord insert and required an additional work step, namely cutting the sections. At the It is also known to press or roll textile cords to join foils with an overlap, but it did exist no need to remove the overlaps.

Ins einzelne gehende Vorschriften über den Aufbau von Eeifen legen jedoch die zulässige Anzahl von Überlappungen und ihre Verteilung auf den Umfang des Reifens genau fest. Folglich erhöhte sich der Arbeitsaufwand bei der Reifenherstellung.However, detailed regulations on the structure of tires lay down the permissible number of overlaps and their Distribution exactly to the circumference of the tire. As a result, the labor involved in manufacturing the tire increased.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur Verbindung von Kautschukfolien anzugeben, bei der keinThe invention is based on the object of specifying a device for connecting rubber foils in which no

Abfall an nichtvulkanisiertem Kautschuk und Stahlkordeinlage anfällt und andererseits der Arbeitsaufwand bei der Herstellung von Reifen mit Textilkordeinlagen verringert wird.Waste of unvulcanized rubber and steel cord insert and on the other hand reduces the amount of work involved in the manufacture of tires with textile cords will.

Diese Aufgabe wird erfindungsgemäß dadurch erreicht, daß die Enden von zwei Kautschukfolien auf einem Tisch übereinandergelegt und mit einem scheibenfomigen Messer abgeschnitten werden, das eine leicht abgestumpfte Schneidkante aufweist und über den Tisch gerollt wird. Die besten Ergebnisse werden erzielt, wenn ein scheibenförmiges Messer verwendet wird, dessen Schneidkante abgerundet oder quer und senkrecht oder etwa senkrecht zu der Ebene des Messers abgeschnitten ist.According to the invention, this object is achieved in that the ends of two rubber sheets are placed one on top of the other on a table and cut with a disc-shaped knife that has a slightly blunted cutting edge and rolled across the table. For best results, use a disc-shaped knife is, whose cutting edge is rounded or cut transversely and perpendicularly or approximately perpendicular to the plane of the knife is.

Die erfindungsgemäße Vorrichtung umfaßt ein scheibenförmiges Messer, das über ein elastisches Zwischenstück, wie etwa eine Feder, ein Federsystem und/oder elastisches Gummi und/ oder Kunststoff, derart an einem gleichmäßig beweglichen Wagen gehalten ist, daß es einen gleichmäßigen Druck entlang der Verbindungslinie auf die zu verbindenden Folien ausübt.The device according to the invention comprises a disc-shaped knife which has an elastic intermediate piece, such as a spring, a spring system and / or elastic rubber and / or plastic, such on a uniformly movable carriage is held that it exerts a uniform pressure along the connecting line on the foils to be connected.

Das Ende einer Kautschukfolie 1 wird auf einen Tisch 2 der Vorrichtung gelegt. Auf diese Folie 1 wird der Anfang der zweiten Kautschukfolie 3 derart aufgelegt, daß die beiden Endstücke in dieselbe Richtung weisen. Wenn die Endstücke aufeinanderliegen, wird ein scheibenförmiges Messer 4- mit leicht abgestumpfter Kante über den Tisch 2 gerollt. Das Messer 4- ist über ein elastisches Zwischenstück 5 an einem Wagen 6 befestigt, der gleichmäßig in Führungen 7 beweglich ist, die parallel zu der Verbindungslinie der beiden Folien verlaufen.

biegen der leicht aneinanderhaftenden Abschnitte der beiden Kautschukfolien 1 und 3 im Bereich ihres einstweiligen Eontaktes entsteht ein gleichförmiges Kautschukband, das zur weiteren Verarbeitung abgeführt wird. Das abgetrennte Endstück 8 der beiden miteinander verbundenen Kautschukfolien wird als verwertbares Halbfertigprodukt zu der Vorrichtung zur Herstellung der Kautschukfolie überführt. Nachdem die auf diese Weise verbundenen Folien gemeinsam mit einer Stahlkordeinlage zwischen den Walzen einer Presse hindurchgeführt worden sind, verbleibt an der Verbindungsstelle auf der gummiüberzogenen Stahlkordeinlage nur eine kaum sichtbare Spur. Die erfindungsgemäße Vorrichtung wird vorteilhafterweise an der Presse angeordnet und kann automatisch gesteuert werden, wenn sie mit der Presse zusammenwirkt.bend the slightly adhering sections of the two Rubber foils 1 and 3 in the area of their temporary contact the result is a uniform rubber band that is used for further processing is discharged. The severed end piece 8 of the two interconnected rubber sheets is transferred as a usable semi-finished product to the device for the production of the rubber sheet. after the In this way connected foils passed together with a steel cord insert between the rollers of a press only a barely visible trace remains at the connection point on the rubber-coated steel cord insert. The device according to the invention is advantageously arranged on the press and can be controlled automatically, when collaborating with the press.
