Abstract
An apparatus for non-contact processing a ribbon-like article includes a conveying device of the ribbon-like article including an inlet section, an outlet section and a connecting part, and at least two operating units configured to perform non-contact processing on the ribbon-like article, the operating units being movable along a loop path. The apparatus also includes a device for varying the speed of movement of said operating units configured in such a way as to vary the speed of each of the operating units, individually, depending on a position thereof along the loop path.
Claims24
An apparatus for non-contact processing a ribbon-shaped article comprising:
- a conveying device of the ribbon-shaped article comprising an inlet section, an outlet section and a connecting part extending between said inlet section and said outlet section;
- at least two operating units, wherein the at least two operating units are laser heads, configured to perform non-contact processing on the ribbon-shaped article, said operating units being movable along a loop path, said loop path comprising a processing portion facing said connecting part along which said operating units can perform non-contact processing on the ribbon-shaped article;
- and
- a device for varying the speed of movement of said operating units, said variation device being configured in such a way as to vary the speed of each of said operating units, individually, according to a position thereof along said loop path.
A method for non-contact processing a ribbon-shaped article comprising in the order:
- arranging at least two operating units configured to perform non-contact processing on the ribbon-shaped article, said operating units being movable along a loop path comprising a processing portion along which said operating units are facing the ribbon-shaped article;
- feeding the ribbon-shaped article at a feed rate on a conveying device;
- performing by means of at least one of said operating units a predetermined non-contact processing on the ribbon-shaped article while said ribbon-shaped article moves at said feed rate and said at least one operating unit moves along said processing portion at a first speed;
- and
- increasing the speed of said at least one operating unit to a second speed, which is higher than said first speed when it has finished non-contact processing on the ribbon-shaped article, at a reset portion of said loop path.
