MACHINE AND PROCESS FOR OBTAINING CELLS FOR ELECTRIC STORAGE BATTERIES AND CELL FOR ELECTRIC STORAGE BATTERY

摘要

Machine (1) for obtaining cells for electric storage batteries, comprising an apparatus (3) for feeding two continuous strips (4) of dielectric material, provided with coupling means (8) for coupling the two strips (4) in their extension; a first and a second apparatus (5′, 5″) for distributing first electrodes (10) of the same polarity and a third apparatus (11) for distributing second electrodes (12) with opposite polarity with respect to the first electrodes (10). The machine comprises a folding head (6) provided with a stacking surface (7) adapted to receive the two strips (4) from the feeding apparatus (3). The third distribution apparatus (11) is adapted to transfer the second electrodes (12) to the coupling means (8), between the two strips (4), spaced from each other along the extension of the strips (4). The feeding apparatus (3) is adapted to release, to the folding head (6), the pair (13) of strips (4) with the second electrodes (12) interposed. The folding head (6) is adapted to receive, from the feeding apparatus (3), a composite layer (14) formed by a section of the pair (13) of strips (4) with a second electrode (12) interposed, with each passage between a first position (A) and a second position (B), translated with respect to the first position (A), forming a fold (45) from two successive composite layers (14); such folding head (6) is adapted to receive, on the layer (14), a first electrode (10) from the first distribution apparatus (5′) when it is in the first position (A) and a first electrode (10) from the second distribution apparatus (5″) when it is in the second position (B), in order to form, on the stacking surface (7), a stack of composite layers (14), alternated with the first electrodes (10). A process for obtaining cells for electric storage batteries and a cell for electric storage batteries also forms the object of the present invention.
