ABSTRACT:
A device for piercing holes in rod-shaped items particularly cigarettes, on which the items are housed inside respective recesses mounted so as to rotate around their own axes on a conveyor moving cross wise in relation to the recesses. A focusing lens is associated with each respective recess. When the conveyor is operated, the focusing lenses are struck successively by a pulsating laser beam and reflected by a reflecting device located between the laser source and the route travelled by the focusing lenses. The beam is then focused by the focusing lenses on to the periphery of the relative items as they turn.
