Abstract: 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).

A second winding head (13), which follows the first winding head (13) along the processing path (P2), is configured to grab the new free end of the composite material (8) and start the winding of the composite material (8) while first winding head (13) is still completing the winding of its own composite material (8).

Abstract: An apparatus (100) for making a coil (B) comprises a feed unit (2) configured to feed at least one strip-shaped article (N) formed by a plurality of strips (N1, N2, N3, N4) and a winding unit (1). The winding unit includes a plurality of winding heads (10) and a movement device (3) of said winding heads (10) configured to displace said winding heads (10) along a working path (P). The apparatus further comprises a storage device (4) configured so as to store a variable amount of said at least one of said strips (N1, N2, N3, N4) and an actuating device of the storage device (4) which displaces said storage device (4) to vary the stored amount of strip.

Abstract: An apparatus (100) for making a coil (B) comprises a feed unit (2) configured to feed at least one strip-shaped article (N) and a winding unit (1). The winding unit includes a plurality of winding heads (10) and a movement device for moving (3) said winding heads (10) configured to displace said winding heads (10) along a working path (P). Each winding head (10) supports a gripping device (11) which is configured to grasp a portion of said strip-shaped article (N) and is configured to wind said strip-shaped article (N) so as to make said coil (B). The movement device (3) is further configured so as to displace a respective winding head (10), when it is grasping said portion of said strip-shaped article (N), along an operative segment (P1) of said working path (P) in a direction discordant to a feed direction (f) of the strip-shaped article.
