A machine which is constructed for slitting travelling webs, such as corrugated boards or similar material, characterized by a slitting tool with the shape of a thin rotary blade, which is provided with a cutting peripheral edge. The rotary blade is contained within a holder so that only a small portion of the cutting edge will emerge from a narrow slot in a wall of the holder, which wall is placed very close to the path of the web. The holder also contains a liquid for cooling and lubricating the rotary blade.
