FIELD: rolled stock production, namely, roll assemblies of stands for cold and hot nonreversing metal rolling. SUBSTANCE: roll assembly of four-high sheet rolling stand includes working and backup rolls with shaped barrels and with working roll chocks non-fixed in axial direction and having lateral guiding surfaces inclined by 1-5 deg relative to axis of working roll. In order to provide enhanced accuracy and planeness degree of sheets backup rolls have convex barrels with curvature of profile line 0.01-0.06 0,01-0,60•10^-3 m^-1 and working rolls have concave barrels with curvature of profile line 0.01-0.05 0,01-0,05•10^-3 m^-1. EFFECT: improved design. 1 cl, 1 tbl, 1 dwg
