摘要: A device and a method for producing zones of desired air permeability in the enveloping material rod-shaped articles, particularly tobacco-processing industry. The comprises beam-guiding focusing an energy-rich beam, generated by radiation source, onto order to form perforation zones, as well multiple beam-generating that generates beam from single beam. is provided with at least one optical element fixed its operating position relative
