The apparatus is provided in a portion of or in relation to the mash seam welder for taking up the copper wire having been used once for welding and squeezed to have a substantially flat sectional profile as taken-up wire and feeding again the taken-up wire as rewound wire to the mash seam welder to be used again for welding between said upper and lower roller electrodes.
