Die Erfindung bezieht sich auf ein Band aus mit einer Kautschukmischung umspritzten Drähten oder Litzen zum Herstellen von Einlagen für Fahrzeugluftreifen aus einem durch schraubengangartiges Aufwickeln des Bandes unter Andrücken der Längskanten erzeugten zylindrischen und in Einlagen zerschnittenen Wickels.The invention relates to a strip of wires or wires overmolded with a rubber mixture Strands for the production of inserts for pneumatic vehicle tires from a screw thread-like winding of the tape while pressing the longitudinal edges produced cylindrical and cut into inserts Wraps.
Die Verwendung eines solchen aus einer einzigen umspritzten Litze bestehenden Bandes ist durch die USA.-Patentschrift 1 464 632 in der Form bekannt, daß es mit dicht nebeneinanderliegenden Windungen in noch vulkanisierfähigem Zustand zu einem über zwei Trommeln laufenden endlosen Wickel aufgewickelt wird, wobei sich die nebeneinanderliegenden Windungen unter Andruck mittels einer besonderen Vorrichtung miteinander verbinden. Zur Verbindung der einzelnen Windungen ist in diesem Fall keine Kalanderwalze erforderlich, wie sie beispielsweise bei einem sonst ähnlichen Wickel nach der USA.-Patentschrift 1519 522 Verwendung findet, um die auf einer Trommel aufgewickelten Windungen eines runden Bandes miteinander zu vereinigen und auf diese Weise einen Wickel mit glatter Oberfläche herzustellen, der nach Auftrennung, beispielsweise mittels eines schrägen Schnittes, eine Vielzahl zueinander paralleler, nebeneinanderliegender flexibler Drähte aufweist.The use of such a tape consisting of a single overmolded strand is made possible by the U.S. Patent 1,464,632 known in the form that it has closely spaced turns wound into an endless roll running over two drums while still vulcanizable is, whereby the adjacent turns under pressure by means of a special Connect the device to each other. In this case, there is no connection between the individual turns Calender roll required, as is the case, for example, with an otherwise similar roll according to the USA patent 1519 522 is used to make the turns of a round wound on a drum To unite the tape with each other and in this way to produce a winding with a smooth surface, which after separation, for example by means of an oblique cut, a plurality of each other having parallel, juxtaposed flexible wires.
Aus der USA.-Patentschrift 2 902 083 ist es weiterhin bekannt, bereits in der Strangpresse eine Mehrzahl nebeneinander herlaufender Drähte gleichzeitig zu umspritzen, wodurch bereits ein Band mit einem flachen, rechteckigen Querschnitt entsteht. Dieses Band wird jedoch im Gegensatz zu dem vorher erörterten Wickel nicht schraubenförmig, sondern in übereinanderliegenden Windungen aufgewickelt. Die Kraft zur Vereinigung der einzelnen Windungen ergibt sich hierbei zwangläufig durch den in dem aufzuwickelnden Band herrschenden Zug.It is also known from US Pat. No. 2,902,083 to have a plurality already in the extrusion press to encapsulate wires running next to each other at the same time, whereby already a tape with a flat, rectangular cross-section is created. However, this tape is contrary to that previously discussed The winding is not helical, but wound in turns one on top of the other. the The force to unite the individual windings inevitably results from the in the to be wound Band ruling train.
Die Erfindung hat zum Ziel, ein Band der eingangs geschilderten Art so auszubilden, daß mit diesem ohne besondere Andruckmittel die nebeneinander beispielsweise auf eine Trommel aufgebrachten Windungen unter Ausnutzung des Zuges in dem aufgewickelten Band miteinander vereinigt werden können.The aim of the invention is to design a band of the type described above so that with this without special pressure means, the windings applied next to one another, for example on a drum can be combined with one another by taking advantage of the train in the wound tape.
Dazu ist erfindungsgemäß vorgesehen, daß das Band beim Spritzvorgang erzeugte abgeschrägte Längskanten zur gegenseitigen Überlappung beim Aufwickeln des Bandes zu einem Wickel aufweist.For this purpose, it is provided according to the invention that the tape produced during the injection molding process is beveled Has longitudinal edges for mutual overlap when winding the tape into a roll.
Auf diese Weise teilt sich trotz der nebeneinander liegend aufgewickelten Bandwindungen eine Komponente
der für die Vereinigung der aufeinanderfolgenden Windungen allein maßgeblichen Radialkraft der
Band aus mit einer Kautschukmischung
umspritzten Drähten oder Litzen zur Herstellung von Einlagen für FahrzeugluftreifenIn this way, despite the band windings wound next to one another, a component of the radial force of the band, which is solely decisive for the union of the successive windings, is shared with a rubber mixture

Weitere Einzelheiten des Bandes gehen aus der folgenden Beschreibung eines in den Figuren dargestellten Ausführungsbeispiels hervor. *Further details of the band can be found in the following description of one shown in the figures Embodiment emerges. *
Die F i g. 1 und 2 stellen einen schematischen Aufriß bzw. Grundriß einer zur Verwendung des Bandes geeigneten Vorrichtung dar.The F i g. 1 and 2 show a schematic elevation and plan view of one for use of the tape suitable device.
In den Figuren sind mit 1 Spulen bezeichnet, auf denen Drahtlitzen C aufgewickelt sind. Eine angemessene Anzahl von Drahtlitzen C wird nach Durchführung durch eine Sicherheitsvorrichtung 2 zusammengefaßt einer Vorwärmvorrichtung 3 zugeführt, in der sie beispielsweise durch Führung über dampfbeheizte Trommeln oder Hindurchleitung elektrischen Stromes vorgewärmt werden.In the figures, 1 denotes spools on which wire strands C are wound. An appropriate number of wire strands C , after being passed through a safety device 2, are combined and fed to a preheating device 3, in which they are preheated, for example, by guiding them over steam-heated drums or passing electric current through them.
Von der Vorwärmvorrichtung 3 gelangen die Drähte zu einer Düse 4 N einer Kautschukstrangpresse 4. Dabei werden sie durch eine Vorrichtung unter Spannung gehalten. Diese Vorrichtung kann auf die Spulen 1 einwirken oder einen Teil der Sicherheitsvorrichtung 2 bilden, sofern sie nicht gesondert vorgesehen ist.From the preheating device 3, the wires pass to a nozzle 4 N of a rubber extruder 4. They are kept under tension by a device. This device can act on the coils 1 or form part of the safety device 2, unless it is provided separately.
In der Düse 4 N der Kautschukstrangpresse werden die Litzen unter Herstellung des angegebenen Profils mit abgeschrägten Längskanten im Abstand nebeneinander liegend mit einer Kautschukmischung umspritzt. Das austretende Band 11 läuft zunächst über eine Ziehmaschine 5, sodann auf eine Wickelvorrichtung 6. Nach Passieren einer Führungsrolle 7 gelangt es durch eine Stoppvorrichtung 8, die das Bandende festhalten soll und mit einem Messer versehen ist, in die Wickelmaschine 9. In letzterer wird es in dichtIn the nozzle 4 N of the rubber extrusion press, the strands are overmolded with a rubber mixture lying apart from one another, producing the specified profile with beveled longitudinal edges. The emerging tape 11 first runs over a drawing machine 5, then onto a winding device 6. After passing a guide roller 7, it passes through a stop device 8, which is intended to hold the tape end and is provided with a knife, into the winding machine 9. In the latter it is in tight

Die Trommel 10 ist zur Führung eines Messers, mit dem der so entstandene endlose Wickel aufgetrennt werden kann, mit einer schrägen Nut 12 versehen. Der aufgeschnittene, einen parallelogrammförmigen Bogen bildende Wickel wird schließlich gefaltet oder zerschnitten, wobei die einzelnen Teile auf einer Reifenformmaschine in Schichten gelegt werden und die Reifenkarkasse bilden.The drum 10 is used to guide a knife with which the resulting endless lap is cut can be provided with an inclined groove 12.
