Abstract

A system for processing an article (A1) for performing a process in a predetermined zone of the article is described, the system comprising: a transport conveyor (2) configured for transporting the article (A1, A2) into a processing zone along a feed direction (d1), a laser source (4), positioned at the processing zone, and configured to perform the process on the article (A1, A2) in said processing zone, at least one video camera (5A, 5B) configured for detecting a frame in the processing zone, a control unit (7) in communication with the video camera (5A, 5B) and the laser source (4), and being configured to detect a relative position of the article (A1, A2) in the frame, and orienting the laser source (4) with respect to the frame as a function of the relative position and a predetermined processing position of the article (A1, A2) in the processing zone. A corresponding method for processing an article (A1, A29 is also described.
