Method for non-contact processing on a ribbon-like article, preferably for the production of electrochemical cells

A method for non-contact processing on a ribbon-like article, preferably for the production of electrochemical cells, comprising:

• providing at least two operating units configured to perform non-contact processing on the ribbon-like article, said operating units being movable along a loop path comprising a processing portion along which said operating units face the ribbon-like article and a reset portion, subsequent to said processing portion along said loop path, wherein said operating units move being placed the one in a different position from the other in said loop path,
• providing said operating units with a set of processing instructions on the basis of which to carry out a predetermined non-contact processing on the ribbon-like article,
• advancing the ribbon-like article on a conveying device,
• performing by at least one of said operating unit the further predetermined non-contact processing provided to said operating unit on the ribbon-like article while said ribbon-like article is moving on said conveying device and at least one of said operating unit is displacing along said processing portion,
• providing one of said operating units with a further set of processing instructions on the basis of which to carry out a further predetermined non-contact processing on the ribbon-like article when said operating unit transits along the reset portion, and
• performing by said operating unit the further predetermined non-contact processing provided to said operating unit on the ribbon-like article while said ribbon-like article is moving at said feed rate and while said operating unit is displacing along said processing portion.
