Manufacturing machine (9) and method for manufacturing a cylindrical electrochemical cell (2) consisting of a spiral winding of a composite material (8) comprising at least two conductor bands (4, 6) and at least two separator bands (5, 7) overlapping one another. They are provided: a plurality of winding heads (13), each of which supports a holding device (14) which is configured to grab an end of the composite material (8) and to rotate on itself around a first rotation axis (15) so as to obtain a spiral winding of the composite material (8); a drum (11) which supports the winding heads (13) and which is mounted in a rotary manner so as to rotate with a continuous law of motion around a second rotation axis (12) in order to move the winding heads (13) along a processing path (P2); and a feeding unit (10) configured to feed the composite material (8) to the winding heads (13).
