APPARATUS AND METHOD FOR MAKING COILS, PREFERABLY FOR AN ELECTROCHEMICAL CELL INTENDED FOR BATTERY PRODUCTION

An apparatus () for making coils, preferably for electrochemical cells intended for battery production, comprises a feed unit () configured to feed at least a first strip-shaped article (N) intended to form a first coil (B) and a second strip-shaped article (N) intended to form a second coil (B), a winding unit () comprising a plurality of winding heads () including at least a first winding head () configured to wind the first strip-shaped article (N) and a second winding head () configured to wind the second strip-shaped article (N) and at least one movement device () of said winding heads () configured to move said first winding head () and said second winding head (). Said first winding head () and said second winding head () define respective winding axes (X X) substantially parallel to each other. Said winding unit () is configured so as to define a separation plane (P), said separation plane (P) being substantially perpendicular to said winding axes (X X) and being positioned so that said first strip-shaped article (N) and said second strip-shaped article (N) are located one on one side and the other on the opposite side of said separation plane (P) at least at said first winding head () and said second winding head ().
