An apparatus for conveying elongated flexible material such as metal strips, wire and tubes by means of rotating shafts in a processing container holding a treatment-fluid for treatment of the material chemically, electrolytically, by pickling, deposition and similar processes, provides for the means of: coiling the material, imparting the coiled material the shape of a helix having a plurality of loops; causing at least a partial immersion of the loops of the helix in the treatment-fluid; advancing the helix in the said container at an advance speed; controlling the entry speeds of the helix relative to a predetermined speed withdrawal of the helix from the container.
