FIELD: rolling-and-inspection machines. SUBSTANCE: driven drum of device is connected with drive drum by means of electromagnetic slip clutch having negative feedback with it by rotational speed through tachogenerator. Excitation winding of clutch is connected to rotational speed setter of driven drum of potentiometric type. Movable contact of potentiometer is output member of roll present radius measuring transducer converting this radius into motion of contact according to preset law ensured by leverage and corresponding to required rotational speed of driven drum. EFFECT: improved quality of material rolling. 4 dwg
