Machine and process for obtaining cells for electric storage batteries and cell for electric storage battery

Machine for obtaining cells for electric storage batteries, which comprises:

• a support structure set on the ground;
• a feeding apparatus for feeding at least one continuous strip of dielectric material, mounted on said support structure;
• a first and a second distribution apparatus for distributing electrodes, wherein said first and said second distribution apparatus are mounted on said support structure;
• a folding head mounted on said support structure and provided with a stacking surface susceptible to receive said at least one continuous strip of dielectric material from said feeding apparatus, and such folding head is movable between a first position and a second position translated with respect to said first position along a direction orthogonal to a lying surface of said at least one continuous strip of dielectric material released from said feeding apparatus in order to obtain a plurality of layers with said electrodes interposed;
• wherein:
• said feeding apparatus is adapted to release, on said folding head, two continuous strips of dielectric material and comprises coupling means for coupling said two continuous strips in their extension with respective opposite internal faces;
• said first distribution apparatus and said second distribution apparatus are adapted to distribute first electrodes having the same polarity;
• said machine comprising at least one third distribution apparatus for distributing second electrodes having opposite polarity with respect to the polarity of said first electrodes, such third distribution apparatus adapted to transfer said second electrodes to said coupling means of said feeding apparatus, between the internal faces of said two continuous strips of dielectric material, spaced from each other, said feeding apparatus being adapted to release towards said folding head said pair of continuous strips with said second electrodes interposed that are spaced from each other along an extension direction of said two continuous strips,
• said folding head, with each passage between said first position and said second position, being adapted to receive from said feeding apparatus a composite layer formed by a section of said pair of continuous strips containing one of said second electrodes and being susceptible to form a fold between two successive layers of said composite layers, and said folding head being adapted to receive on said composite layer one of said first electrodes from said first distribution apparatus when it is situated in said first position and one of said first electrodes from said second distribution apparatus when it is situated in said second position in order to form, on said stacking surface, a stack composed of said composite layers alternated with said first electrodes.
