Apparatus for forming electrical energy storage devices

An apparatus for forming devices for storing electrical energy, of the type comprising a cylindrical winding formed by at least one anode element, a cathode element and a separator interposed between said anode and cathode elements, and having a pair of metal disks applied at the opposite ends thereof, adapted to make contact with the terminals of said anode and cathode elements, said apparatus comprising:

• a rotatable member for carrying said cylindrical windings in succession by means of gripping members at a series of operative stations;
• first feeding means adapted to feed said cylindrical windings in an ordered sequence;
• means for transferring said cylindrical windings to said rotatable member;
• second feeding means adapted to feed to said rotatable member of said pairs of metal disks;
• means for centering said metal disks and said respective cylindrical windings respectively configured to simultaneously align the disks of each of said pair of metal disks with said terminals of the respective cylindrical winding and to position the axis of the cylindrical winding in a predefined position;
• means for welding said pairs of metal disks configured to simultaneously weld each pair of metal disks to the respective terminals of said anode and cathode elements of the cylindrical windings.
