Title (EN) MANUFACTURE OF FINELY PERFORATED SHEET MATERIAL
(FR) FABRICATION D'UN MATERIAU EN FEUILLE A MINCES PERFORATIONS
Abstract: front page image
(EN)A method of perforating a sheet material (11) comprising removably supporting the sheet material (11) on a support surface of a support body (12), exposing the sheet material to a laser beam (16) to form perforations in the sheet material (11) and removing the resultant perforated sheet material (11) from the support body (12). The support surface has a low reflectivity to the laser beam such that the geometry of the perforations is not significantly affected by reflected radiation.
(FR)Le procédé décrit, qui permet de perforer un matériau en feuille (11), consiste à maintenir de façon amovible le matériau en feuille (11) sur une surface de support d'un corps de support (12), à exposer le matériau en feuille à un faisceau laser (16) pour former des perforations dans le matériau en feuille (11) et à retirer du corps de support (12) le matériau en feuille perforé (11) qui en résulte. La surface de support se caractérise par un faible pouvoir de réflection du faisceau laser, de sorte que la géométrie des perforations n'est pas affectée de façon sensible par le rayonnement réfléchi.
