A roll stand for a planetary rolling mill having a housing, and two stationary support members mounted in chocks, with rolling segments and intermediate and work rolls mounted in rotationally driven cages. The support members have a plurality of rolling segments, spaced about an outer surface thereof. By the turning of the support members, the rolling segments can be brought, in each case, into working position. In order to be able to effect a change of the rolling segments while using the favorable torque division of the drive system for the roll cages, the support members (1) are rotatably mounted in their chocks (15) adapted to be clamped (20) in the working position of the rolling segments (16). A drive is selectably engaged to rotate the support member into a new working position.
