Bei den zum Auswalzen von Hohlkörpern oder massiven, cylindrischen Körpern dienenden Walzwerken, bei welchen die Walzenachsen parallel oder etwas geneigt zur Längsachse des Walzstückes liegen, macht sich der Uebelstand geltend, dafs in der Regel sämmtliche Walzstücke unrund werden. Dieselben erhalten, wenn z. B. ein Walzwerk mit vier Walzen verwendet wird, einen Querschnitt, welcher annähernd ein Fünfeck bildet, während, wenn das Walzwerk mit drei Walzen versehen ist, das Walzstück einen Querschnitt erhält, welcher vier vorspringende Stellen zeigt. Infolge dieser ungünstigen Arbeitsweise waren diese Walzwerke bisher fast nicht zu verwenden.In the case of those used for rolling out hollow bodies or solid, cylindrical bodies Rolling mills in which the roll axes are parallel or slightly inclined to the longitudinal axis of the rolled piece, the disadvantage asserts itself that, as a rule, all Rolled pieces become out of round. Obtain the same if e.g. B. a rolling mill with four Rolling is used, a cross-section which approximately forms a pentagon, while, when the rolling mill is provided with three rolls, the rolled piece is given a cross-section which shows four protruding spots. As a result of this unfavorable way of working, these were Rolling mills almost impossible to use up to now.
Dieser Uebelstand ist bei dem dargestellten Walzwerk (Fig. 1 und 2) dadurch beseitigt, dafs den Walzen verschiedene Entfernungen von einander gegeben worden sind. Es hat sich nämlich herausgestellt, dafs, wenn die Walzen gleichmäfsig vertheilt sind, ein immerwährendesThis disadvantage is eliminated in the rolling mill shown (Figs. 1 and 2) by the fact that the rollers have been given different distances from each other. It has namely, it has been shown that, when the rollers are evenly distributed, an everlasting one
