Abstract

A process for micro-perforating hides using a laser, characterized by: positioning the hide below a plurality of laser sources disposed substantially aligned along a straight line perpendicular to the hide advancement axis, each laser source being provided with a galvanometric head comprising deflector mirrors, activating the laser sources to generate a first series of holes, the total triggering, ionization and quenching time of each laser source to form a hole being less than 10 µsec., each laser source generating, during the ionization stage, a pulse of power greater than its rated power for a time less than the rated working time, operating the deflector mirrors repetitively, alternately with the repetitive activation of the laser sources, to generate successive series of holes until completion of the field of action of the galvanometric head, advancing the hide/laser sources through a further length corresponding to the length of the hide surface treated by the galvanometric head measured in the direction of advancement of the hide/laser sources.
