Description

Gegen Gleiten werden Radreifen aus Gummi mit gemusterten Vertiefungen versehen, die Profile genannt werden. Diese verschwinden beim Gebrauche zunächst in der Mitte der Lauffläche, die dadurch glatt wird und gegen Gleiten keine Sicherheit mehr bietet.To prevent sliding, rubber wheel tires are provided with patterned depressions, which are called profiles. When in use, these first disappear in the middle of the running surface, which makes it smooth and no longer offers any security against sliding.

Um diesen Übelstand zu beseitigen, bestehen Reifenlaufflächen gemäß dieser Erfindung aus einer wie üblich profilierten Kautschukmasse, die aber etwa am Grunde der Profilrillen nach den Gewebelagen zu in eine besondere Kautschukmasse übergeht, deren Oberfläche in bekannter Weise bei Abnutzung dauernd rauh bleibt.To overcome this drawback, there are tire treads according to this invention made of a rubber mass profiled as usual, but which is roughly at the bottom of the Profile grooves merge into a special rubber compound after the fabric layers As is known, the surface remains permanently rough when worn.

Beispielsweise kann eine Masse verwendet werden, bei der durch Herausfallen einzelner Elemente fortlaufend sich erneuernde Unebenheiten in der Lauffläche hervorgerufen werden. Die hierbei zur Anwendung kommende Gummimischung kann sich z. B. zusammensetzen aus einer Gummibasis, in die ein weicher, zusammendrückbarer Stoff, z. B. Korkschrot oder Holundermark, eingemischt ist.For example, a mass can be used in which individual falls out Elements continuously renewing bumps in the running surface are caused. The rubber mixture used here can be, for. B. assemble from a rubber base into which a soft, compressible fabric, e.g. B. crushed cork or elder pulp, is mixed in.

Das : Gleiten wird also anfangs durch Profile, später durch eine rauhe Kautschukmasse verhütet. Die Zeichnung stellt einen Querschnitt durch einen der Erfindung entsprechenden Reifen dar, in der die punktierte Linie etwa die Grenze bezeichnet, an welcher die normale profilierte Mischimg in die Masse übergeht, deren Oberfläche stets rauh bleibt. Diese beiden verschieden schraffierten Mischungen bilden ein vollkommen zusammenhängendes Ganzes, das in einem einzigen VuI-kanisationsprozesse gleichzeitig erzielt werden kann.That: sliding is initially through profiles, later through a rough rubber compound prevent. The drawing shows a cross section through one according to the invention Tires represent, in which the dotted line indicates approximately the limit at which the normal profiled mixing in the mass passes over, the surface of which always remains rough. These two differently hatched mixtures form a completely coherent whole, which in a single VuI canization process can be achieved simultaneously.

Nach Verschwinden der Profile tritt also eine Lauffläche zutage, die das Gleiten des nun fast profillosen Reifens durch ihre Rauheit verhindert und die Eigenschaft des Nichtgleitens auf die gesamte Lebensdauer des Reifens ausdehnt.After the profiles disappear, a running surface emerges that prevents the sliding of the now almost treadless tires prevented by their roughness and the property of non-slip extends over the life of the tire.

Die Herstellung solcher Reifen bietet keine Schwierigkeiten, weil weder neue Formen noch wesentliche Änderungen des Fabrikationsganges erforderlich sind.The manufacture of such tires offers none Difficulties because neither new forms nor significant changes in the production process required are.
