Abstract
Apparatus for engraving a rotating cylinder by means of a laser, in which the laser beam is focused onto a small area of the cylinder surface by a lens, including means for defining a path for the flow of compressed air across the path of the laser beam, and a suction device communicating with the region between the lens and the cylinder for extracting air from this region, the flow of air serving to remove debris from the area being engraved and to prevent it from reaching the lens.
