Device for cutting a web of material

A device for cutting a web of material, comprising:

• movement means by which a web of material to be cut is made to advance and defining for the web a feed path which is at least partly rotatable about a central axis;
• the movement means comprising at least a conveyor mounted around the central axis and defining an at least partly curved cutting zone;
• at least one laser cutting head laser equipped with a laser source configured to generate a laser beam, and an optical system configured to direct the laser beam towards the cutting zone;
• Wherein the optical system of the cutting head comprises at least one directing member located inside the conveyor to direct the laser beam away from the central axis towards the cutting zone;
• the directing member being rotatable about its axis of rotation and oriented in such a way that the laser beam defines on the web a cutting line transversal to the feed path of the web.
