Apparatus and method for non-contact processing on a ribbon-like article, preferably for producing electrochemical cells

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

• a conveying device of the ribbon-like article comprising an inlet section, an outlet section and a connecting segment extending between said inlet section and said outlet section, and
• 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, said loop path comprising a processing portion facing said connecting segment along which the operating units can perform non-contact processing on the ribbon-like article,
• wherein said conveying device being configured to advance the ribbon-like article at a feed rate along said connecting segment and said operating units are configured to displace at a first speed along said processing portion, wherein the speed difference between said first speed (and said feed rate is lower than a predetermined value.
