Description

Reparatureinlage für Luftreifen Die Reparatureinlage für Luftreifen nach dem Hauptpatent besteht aus einem in Gummischichten eingebetteten Metallgewebe sowie aus weiteren Faserstoffgeweben zu beiden Seiten der Gummischichten, die ebenfalls mit Gummi überdeckt sind. Hierbei sind in die Fäden des Metallgewebes Faserstoffäden eingelagert, wodurch beim Vulkanisieren des Pflasters eine gute Verbindung der in das Metallgewebe [eingelagerten Faserstoffäden mit den umliegenden Gummischichten erhalten und ein Lösen des Metallgewebes aus dem Gummi verhindert wird.Repair insert for pneumatic tires The repair insert for pneumatic tires according to the main patent consists of a metal mesh embedded in rubber layers as well as from other fibrous fabrics on both sides of the rubber layers, which are also are covered with rubber. There are fiber threads in the threads of the metal fabric embedded, which means that the in the metal mesh [embedded fiber threads with the surrounding rubber layers obtained and a loosening of the metal mesh from the rubber is prevented.

Nach der vorliegenden Erfindung wird die Verbindung des Metallgewebes .mit den umgebenden Gummischichten dadurch verbessert, daß die in das Metallgewebe eingelagerten Faserstoffäden mit Rohgummi, insbesondere einer Gummilösung, getränkt werden. Es ist zwar bei -Reifenpflastern ohne Verstärkung durch ein Metallgewebe bekannt, den Faserstoffaden des Faserstoffgewebes mit Rohgummi zu tränken, ehe er mit der Rohgummilage zusammenvulkanisiert wird. Da eine Verstärkung des Pflasters durch das Metallgewebe fehlt, so hat ein solches Pflaster nur eine geringe Haltbarkeit und erteilt der Flickstelle des Reifens eine geringe Festigkeit.According to the present invention, the connection of the metal mesh .with the surrounding rubber layers improved in that the in the metal mesh stored fiber threads with raw rubber, especially a rubber solution, soaked will. It is true that tire plasters are not reinforced by a metal mesh known to soak the fiber thread of the fiber fabric with raw rubber before he is vulcanized together with the raw rubber layer. As a reinforcement of the plaster If the metal mesh is missing, such a plaster has only a short shelf life and gives poor strength to the patch of the tire.

Durch das gemäß der Erfindung vorgesehene Tränken der in das Metallgewebe eingelagerten Faserstoffäden mit Rohgummi wird :eine besonders innige Verbindung des Metallgewebes mit den umliegenden Gummischichten :erzielt, da beim Vulkanisieren der erhitzte Rohgummi der umliegenden Gummischichten durch die Maschen des Metallgewebes hindurchtritt und sich mit dem von innen aus dem gummierten Faserstoffaden herausdrängenden Rohgummi vermischt. Eine derartige innige Verbindung ist bei Verwendung einfacher Metalldrähte ohne eingelagerte Faserstoffäden nicht zu erreichen. Dadurch wird auch eine Reibung des Metallgewebes mit den umgebenden Faserstoffgeweben beim Walken des Reifens und die damit verbundene schädliche Erwärmung und allmähliche Zerstörung des Gewebes verhindert. Das Tränken des Faserstoffadens mit Rohgummi, insbesondere einer Gummilösung, gibt dem Gewebe außerdem eine größere Elastizität und erhöht dadurch die Festigkeit der Reparatureinlage. Die Ausbildung der Reparatureinlage kann wie bei dem Ausführungsbeispiel des Hauptpatents vorgenommen werden.By soaking provided according to the invention in the metal mesh embedded fiber threads with raw rubber becomes: a particularly intimate connection of the metal mesh with the surrounding rubber layers: achieved because during vulcanization the heated raw rubber of the surrounding rubber layers through the mesh of the metal fabric passes through and with the raw rubber pushing out of the rubberized fiber thread from the inside mixed. Such an intimate connection is when using simple metal wires cannot be reached without embedded fiber threads. This also creates friction of the metal fabric with the surrounding fibrous fabric when the tire is fulled and the associated harmful heating and gradual destruction of the tissue prevented. Soaking the fiber thread with raw rubber, especially a rubber solution, also gives the fabric greater elasticity and thereby increases its strength the repair insert. The formation of the repair insert can be as in the embodiment of the main patent.
