    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 is rotatably mounted to rotate with a continuous law of motion around a second rotation axis (12) so as 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 segment of the processing path (P2) is substantially straight and each holding device (14) is configured to grab one end of the composite material (8) and hence start the spiral winding of the composite material (8) while the corresponding winding head (13) moves along the substantially straight segment of the processing path (P2).

    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.

    Abstract: A method for non-contact processing on a ribbon-like article includes providing at least two operating units configured to perform non-contact processing on the non-contact ribbon-like article. Operating units are movable along a loop path. The operating units is provided with a set of processing instructions on the basis of which to carry out a predetermined non-contact processing on the ribbon-like article. The non-contact ribbon-like article advances on a conveyor device. At least one of said operating units performs the predetermined non-contact processing on the ribbon-like article. One of the operating units is provided with a further set of processing instructions on the ribbon-like article when said operating unit transits along a reset portion of the loop path. The operating unit performs the further predetermined non-contact processing provided.
