FIELD: metallurgical production, namely cleaning and finishing surface of rolled metallic strips. SUBSTANCE: apparatus includes metallic strip, rollers, uncoiler, coiler, rotary holder, vacuum chamber, vacuumizing system, waste material trap, cooling system, fluid-tight inlet, fluid-tight outlet, electronic-plasma modules, carrier. Surface of metallic strip is cleaned in addition at two sides in vacuum by means of electric arc discharges in mode corresponding to raising portion of volt-ampere characteristic and with use of graphite as anode and pressure rollers as cooler. EFFECT: enhanced quality of cleaned strip at both sides, increased efficiency of method. 3 cl, 4 dwg
