Abstract
A device for cutting a strip fed continuously on a roller through a cutting station where a series of at least partial transverse cuts are made successively in the strip by a cutting unit. On the cutting unit, a hollow rotary drum receives a laser beam emitted by a laser source, and focuses the beam at at least one point which, as the drum rotates, moves along an annular trajectory, the plane of which intersects the route of the strip at the cutting station and forms a given angle with a line intersecting the route of the strip.
