ABSTRACT:
A method and apparatus for forming perforations in articles in the form of bars, in which, during their movement through a piercing station, the articles are pierced by means of beams of laser rays emitted in a predetermined sequence by laser emitters, which can be laser generators or simple reflectors so positioned with respect to each said article to be pierced as to maintain the path length followed by the laser rays to form each perforation, once focused, constantly equal to the focal length thereof.
