Der Erfinder hat sion nun das Problem gestellt, Stahl als Aussonschicht und Aluminium als Innenschicht zu verwenden, ohne dass ein besonderer Vereinigungsprozess durch Erwärmung oder elektrischen Strom und ohne dass eine Zwischenschicht aus Lötmetall erforderlich wird.
Er erreicht diesen Zweck dadurch, dass er einen Zylinder aus hartem Metall, wie Stahl, über einen Zylinder aus leichtem Metall, wie Aluminium, stülpt und dann durch Auswalzen auf der Innenwand einer Hohlmatrize den äusseren Zylinder gleichzeitig mit der Prägung versieht und mit dem inneren Zylinder vereinigt. Dies ist eine zweckmässige LÖsung des Problems, weil zunächst schwammiges, galvanisch niedergeschlagenes Metall nicht vorhanden ist, vielmehr können gezogene, also infolge der Bearbeitung ausserordentlich feste, auf gcnauestes Mass gebrachte Rohre aus Stahl und Aluminium verwendet werden.
Ferner werden beide Schichten des Rades gleichzeitig durch den Walzvorgang energisch gehärtet, ein Vorzug, der bei der nachträglichen Vernicklung oder nachträglichen Hintergiessung und Hinterlegung geprägter Räder nicht erreicht wird. Ausserdem wird, da bei der mit dem Auswalzen verbundenen Prägung das Metall der Innenschicht in das der stählernen Aussenschicbt besonders an den Stellen, wo diese sich in die Prägung der Matrize hineinzieht, eindringt, eine vorzügliche Vereinigung beider Schichten und eine nicht minder gute Versteifung der dünnen, harten Aussenschicht erzielt, und zwar weit besser, wie bei jedem anderen Verfahren, denn der beim Auswalzen auftretende hohe Drucke macht die
Bildung von irgendwelchen,
sei es auch noch so geringen Hohlräumen zwischen den beiden
Schieilten gänzlich unmöglich.
Aus dem Vorangegangenen ergibt sied, dass durch vorliegende Erfindung nicht bloss das

The inventor has now posed the problem of using steel as the Ausson layer and aluminum as the inner layer without a special joining process by heating or electric current and without an intermediate layer of solder being required.
He achieves this purpose by slipping a cylinder made of hard metal, such as steel, over a cylinder made of light metal, such as aluminum, and then by rolling on the inner wall of a hollow die, embossing the outer cylinder with the embossing and with the inner cylinder united. This is an expedient solution to the problem, because initially spongy, electroplated metal is not available; instead, drawn tubes made of steel and aluminum, which are extraordinarily strong as a result of the machining, can be used.
Furthermore, both layers of the wheel are vigorously hardened at the same time by the rolling process, an advantage that is not achieved with subsequent nickel plating or subsequent casting and backing of embossed wheels. In addition, since the metal of the inner layer penetrates into that of the steel outer layer in the stamping associated with rolling, especially at the points where it is drawn into the stamping of the die, an excellent combination of both layers and no less good stiffening of the thin ones , hard outer layer is achieved, and much better than with any other process, because the high pressure that occurs during rolling makes the
Formation of any
no matter how small voids between the two
It was completely impossible.
From the foregoing it follows that the present invention does not just mean that
