An electrolytic apparatus for treating continuous strip material comprises a tank defining a rinse chamber and a contact roller assembly which includes an idler roller and two driven electrical contact rollers supported by shafts for rotation about vertical axes to define a serpentine path for strip material passing through the chamber. Three sleeves project upwardly from the bottom wall of the tank to a position above the liquid level in the chamber and respectively receive the shafts therethrough. Each electrical contact roller has a diametrically enlarged annular flange at its upper end disposed externally of the chamber. A brush holder associated with each flange carries a plurality of carbon brushes which engage a radially disposed surface of the flange. Torque limiters are provided for limiting the torque which may be applied to the driven contact rollers.
