MANUFACTURE OF A FINE PERFORATED MATERIAL. |
| abstract |
The disclosed method of perforating sheet material (11) includes releasably holding 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 to remove from the support body (12) the resulting perforated sheet material (11). The support surface is characterized by a low reflectance of the laser beam, so that the geometry of the perforations is not significantly affected by the reflected radiation. |
