Abstract

Bei einer Zweiwalzen-Rundmaschine (1) werden zusätzlich zu der druckelastischen Führungswalze (3, 5) und der druckstarren Rundwalze (6) druckelastische Walzen (8, 10; 11, 13) vorgesehen, welche eine Rundungsfunktion und auch eine Stützfunktion für die Rundwalze 6 haben. Die weiteren Walzen 8 und 11 können ferner durch eine Stützwalze (14) abgestützt sein. Auf diese Weise wird eine Rundmaschine geschaffen, welche sehr gute Rundeigenschaften auch bei kleinen Rundungsdurchmessern aufweist.
