A device for cutting a web of material, comprising: a movement system by which the 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 system comprising a conveyor mounted around the central axis and defining an at least partly curved cutting zone; a laser cutting head including 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 laser cutting head comprises a 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 an axis of rotation and oriented such that the laser beam defines on the web a cutting line transversal to the feed path of the web; wherein the directing member is rotatable at least between a first angular, start-of-cutting position and a second angular, end-of-cutting position, and wherein the conveyor comprises a rotatable drum having an at least partly spherical lateral surface constituting the cutting zone and being curved both along the feed path and transversely to the feed path; the directing member being located at a center of the lateral surface so as to remain equidistant from all points of the cutting zone.
