The invention relates to a roll supporting device to correct the roll gap in a cluster mill for strips. Each working roll (W1, W2) has at least one set of supporting rollers R allocated to it, which comprises supporting rollers (4) distributed over the entire axial length of the working roller (W1, W2) and supporting rollers (4) fitted to rotate on a bearing spindle (3) retained in the mill housing (2). The bearing spindle (3) is supported on bearings (5) arranged between the supporting rollers (4) and borne by the mill housing (2), said bearing position being adjustable by appropriate adjusting devices by means of adjusters K with wedges (6). In order to correct the roll gap following the various elastic deformations relatively easily, several adjusters (K) are set by a single, shared adjusting drive (8-11).
