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.

Figure 00000001
In a two-roller round machine (1), in addition to the pressure-elastic guide roller (3, 5) and the pressure-rigid round roller (6), pressure-elastic rollers (8, 10; 11, 13) are provided, which have a rounding function and also a support function for the round roller 6 to have. The further rollers 8 and 11 can also be supported by a support roller (14). In this way, a rounding machine is created which has very good rounding properties even with small rounding diameters.
