[origin: WO2022106093A1] The invention relates to a roll device (1) for rolling metal strips, comprising at least a first and a second work roll (4, 6, 6') which define a roll gap (W) therebetween, and at least a first and a second support roll (11, 12), wherein: in a common rolling stand (2), at least one work roll (4, 6') is mounted in work roll chocks (5, 9') and the support rolls (11, 12) are mounted in support roll chocks (13, 14); the work roll chocks (5, 9') are designed such that the first and/or the second work roll (4, 6') can each be replaced by a roll arrangement (10) having a work roll (6) with a smaller diameter and at least one additional roll (8); and the work roll (6) with the smaller diameter is supported via the additional roll (8), the additional roll is mounted in additional roll chocks (7), and the work roll with the smaller diameter is situated in work roll bearings (9) of the additional roll chocks (7). The invention also relates to a roll arrangement (10) for use in such a roll device (1), and to a method for converting a roll device (1).
