Description

Die Erfindung betrifft eine Vorrichtung zum Verbinden aufeinandergelegter Enden von Folien aus vulkanisierbarem Kautschuk, insbesondere zum nachfolgenden Überziehen von Stahldrahteinlagen mit Kautschuk oder zum Aufbringen von Deckschichten auf mit Kautschuk überzogene Textilkordeinlagen.The invention relates to a device for connecting ends of foils made of vulcanizable rubber that are placed one on top of the other, in particular to the subsequent one Coating steel wire inserts with rubber or for applying cover layers to them with rubber covered textile cords.

Bisher ist das Verbinden der beiden Ränder der Deckschichten beim Überziehen von Stahldrahteinlagen mit einer Folie aus vulkanisierbarem Kautschuk 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 vulkanisierbaren Kautschukgemisches eine dauerhafte Verbindung zwischen den beiden Enden der beiden Kautschukfolien.So far, the connection of the two edges of the cover layers when covering steel wire inserts with a film made of vulcanizable rubber has been involved With the help of rollers or presses it has been carried out in such a way that one end of one film is over the beginning the second slide has been placed. The stickiness of the vulcanizable rubber mixture ensures a permanent bond between the both ends of the two rubber sheets.

Ein Verfahren dieser Art ist in der DE-AS 11 77 813 v, beschrieben, wobei nach diesem Verfahren der Anfang einer Folie aus Kautschuk über das Ende einer anderen gelegt wird und die beiden Folien an ihrer Überlappungsstelle mit Hilfe einer durch Federkraft angedrückten Rolle miteinander verbunden werden. An der Stelle der Verbindung der Folien weist das durch Zusammenfügen zweier Folien entstandene Kautschukband eine wulstförmige Verdickung auf.A method of this type is described in DE-AS 11 77 813 v, according to which the beginning of a rubber sheet is placed over the end of another and the two sheets are connected to one another at their point of overlap with the aid of a roller pressed by spring force will. At the point where the foils are connected, the rubber band produced by joining two foils has a bead-like thickening.

Etwas anders wird nach dem in der US-PS 20 35 682 beschriebenen Verfahren vorgegangen. Hierbei werden die Enden der zwei zu verbindenden Folien gleichsinnig übereinandergelegt, in ihrer ganzen Breite durch eine Andrückkante an einen entsprechend großen Tisch angedrückt, wobei sie verkleben, und dann entlang ihrer Verbindungslinie mit einem geraden Messer von der w> Länge der Folienbreite abgeschnitten. Hierbei entsteht ein Wulst von der doppelten Dicke des Kautschukbandes, der aus der Ebene des Kautschukbandes heraussteht.The procedure described in US Pat. No. 2,035,682 is somewhat different. Here will be the ends of the two foils to be connected placed one above the other in the same direction, in their entire width through one The pressure edge is pressed against a correspondingly large table, whereby they stick together, and then along it Cut the connecting line with a straight knife from the length of the film width. This creates a bead twice the thickness of the rubber tape protruding from the plane of the rubber tape.

Werden derartige Folien mit wulstförmigen Verdik- > , kungen an den ursprünglichen Verbindungsstellen zusammen mit einer Stahldrahteinlage zwischen den beiden Walzen einer Presse hinHnrrhgeführt. bleibt dieAre such films with bead-shaped Verdik-> , kungen at the original connection points together with a steel wire insert between the two rollers of a press. remains the Verdickung der Kautschukschicht an der Überlappungsverbindung bestehen, während die Stahldrahteinlage in diesem Bereich einer ungleichmäßigen Verbreiterung unterworfen wird. Diese verdickten Abschnitte können im Hinblick auf die an die Ausführung von Reifen zu stellenden Anforderungen nicht mit weiterverarbeitet werden. Daher wurde bisher das gesamte Band der mit Kautschuk überzogenen Stahldrahteinlage zu Einlageteilen zerschnitten, wobei die verdickten Abschnitte abgeschnitten wurden.There are thickening of the rubber layer at the overlap connection, while the steel wire insert is subjected to an uneven widening in this area. These thickened sections cannot be processed further with regard to the requirements placed on the design of tires. Therefore so far the whole Tape of the rubber-coated steel wire insert cut into insert parts, which thickened Sections were cut off.

Dieses Verfahren führte zu Materialverlusten des hochwertigen Kautschukgemisches und der teuren Abschnitte der verlöteten Stahldrahteinlage und erforderte einen zusätzlichen Arbeitsschritt, nämlich das Schneiden der Abschnitte. Beim Pressen oder Walzen von Textilkordeinlagen ist es ebenfalls bekannt, Folien unter gegenseitiger 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 one Sections of the soldered steel wire insert and required an additional work step, namely that Cutting the sections. When pressing or rolling textile cords, it is also known to use foils to join under mutual overlap, but there was no need to close the overlaps remove.

Detaillierte Vorschriften über den Aufbau von Reifen legen jedoch die zulässige Anzahl von Überlappungen und ihre Verteilung auf den Umfang des Reifens genau fest Folglich erhöht sich der Arbeitsaufwand bei der Reifenherstellung.Detailed regulations on the construction of tires however, precisely specify the permissible number of overlaps and their distribution on the circumference of the tire fixed As a result, the labor involved in manufacturing tires increases.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung anzugeben, mit der das Verbinden zweier übereinanderg<;legter Folien aus vulkanisierbarem Kautschuk derart erfolgen kann, daß entlang der Verbindungslinie keine Verdickung infolge einer Überlappung der beiden Kautschukfolien entsteht, sondern daß die beiden Folien auf Stoß miteinander verbunden werden und somit ein Kautschukband von gleichmäßiger Dicke entstehtThe invention is based on the object of specifying a device with which the connection of two superimposed <; laid foils made of vulcanizable Rubber can be made in such a way that no thickening occurs along the connecting line as a result of an overlap between the two rubber foils, but rather that the two foils are connected to one another in abutment and thus a rubber band of uniform thickness is formed

Diese Aufgabe wird bei einer Vorrichtung der eingangs erwähnten Gattung mit den im Kennzeichen des Anspruchs 1 wiedergegebenen Merkmalen gelöst. Eine vorteilhafte Ausgestaltung ist im Unteranspruch angegeben.In the case of a device of the type mentioned at the outset, this task is carried out with the characteristics in of claim 1 reproduced features solved. An advantageous embodiment is in the dependent claim specified.

Infolge der abgestumpften Kante und der fortschreitenden Bewegung des elastisch angedrückten scheibenförmigen Messers werden die beiden Folien entlang der Schnittlinie verklebt und bilden nach ihrem Auseinanderschlagen, d.h. nach dem Umklappen der oben liegenden Folie in die Ebene der unteren um die Schnittlinie ein zusammenhängendes Kautschukband gleichmäßiger Dicke. Beim Aufbringen einer, solchen Kautschukbandes auf Stahldrahteinlagen entstehen keinerlei Abschnitte, die herausgeschnitten werden müssen. Die abgeschnittenen unregelmäßigen Enden der aufeinandergelegten Kautschukfolien sind reiner vulkanisierbarer Kautschuk und können wieder in die Vorrichtung zur Herstellung der Folien zurückgeführt werden. Es ergeben sich somit beträchtliche Einsparungen an Stahldrahteinlagen und Kautschuk. Außerdem werden die Arbeitsschritte des Schneidens überflüssig, so daß der Einsatz der erfindungsgemäßen Vorrichtung, abgesehen von der Einsparung von Stahldrahteinlage und Kautschukgemisch, durch Ausschaltung verschiedener Arbeitsschritte eine Erhöhung des Produktionsausstoßes von Stahleinlagen für Reifen und von Reifen mit Textilkordeinlage ermöglicht.As a result of the blunted edge and the progressive movement of the resiliently pressed disc-shaped knife, the two foils along the Cutting line stuck together and form after they are broken apart, i.e. after folding over the above lying film in the plane of the lower around the cutting line a continuous rubber band uniform thickness. When such a rubber tape is applied to steel wire inserts no sections that need to be cut out. The cut off irregular ends The rubber foils placed on top of one another are pure vulcanizable rubber and can be put back into the Device for the production of the foils are returned. This results in considerable savings in steel wire inserts and rubber. aside from that the steps of cutting are superfluous, so that the use of the device according to the invention, apart from the saving of steel wire core and rubber mixture, by eliminating various work steps, an increase in the production output of steel core for tires and of tires with Textile cord insert allows.

Die erfindungsgemäße Vorrichtung ist beim Verbinden aller Arten von Folien aus vulkanisierbarem Kautschuk, und zwar sowohl aus natürlichem als auch aus synthetischem Kautschuk und deren Mischungen, einsetzbar.The device according to the invention is useful in joining all types of foils from vulcanizable Rubber, both from natural and synthetic rubber and mixtures thereof, applicable.

Das Ende einer Folie 1 aus vulkanisierbarem Kautschuk wird auf einen Tisch 2 der Vorrichtung gelegt Auf diese Folie 1 wird der Anfang einer 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 Ober den Tisch 2 gerollt Das Messer 4 ist über ein elastisches Zwischenstück 5 an einem Wagen 6 befestigt, der gleichmäßig in Führungen 7 bewegbar ist, die parallel zu der Verbindungslinie der beiden Folien I1 3 verlaufen.The end of a film 1 made of vulcanizable rubber is placed on a table 2 of the device. The beginning of a second rubber film 3 is placed on this film 1 in such a way that the two end pieces point in the same direction. When the end pieces lie on top of one another, a disc-shaped knife 4 with a slightly blunted edge is rolled over the table 2. The knife 4 is attached via an elastic intermediate piece 5 to a carriage 6, which can be moved evenly in guides 7 which are parallel to the connecting line of the two foils I 1 3 run.

Nachdem das doppeUagige Endstück entlang der Bahn des Messers 4 abgeschnitten worden ist ist eine Verbindung der beiden Folien I1 3 entstanden. Nach dem Zurückbiegen der leicht aneinanderhaftenden Abschnitte der beiden Folien 1 und 3 im Bereich ihres einstweiligen Kontaktes entsteht ein gleichförmiges Kautschukband, das zur weiteren Verarbeitung abgeführt wird. Das abgetrennte Endstück 8 der beiden miteinander verbundenen Folien 1,3 wird als verwertbares Halbfertigprodukt in die Vorrichtung zur Herstellung der Folien 1,3 zurückgeführt Nachdem die auf diese Weise verbundenen Folien 1,3 gemeinsam mit einer Stahldrahteinlage zwischen den Walzen eines Kalanders hindurchgeführt worden sind, verbleibt an der Verbindungsstelle auf der kautschuküberzogenen Stahldrahteinlage nur eine kaum sichtbare Spur.After the double-layer end piece has been cut off along the path of the knife 4, a connection between the two foils I 1 3 has arisen. After the sections of the two foils 1 and 3, which are slightly adhering to one another, have been bent back in the area of their temporary contact, a uniform rubber band is produced, which is removed for further processing. The separated end piece 8 of the two interconnected foils 1,3 is returned as a usable semi-finished product to the device for producing the foils 1,3. only a barely visible trace remains at the connection point on the rubber-coated steel wire insert.
