Verfahren zur Erzeugung von konischen Perforationen in plattenförmigen Dokumenten |
| 摘要 |
<p>Production of conical perforations in plate-like objects comprises moving a laser beam in the form of a closed curve on the edge of the perforation to be formed. The intensity and speed of the laser beam are selected so that the cross-section is reduced with increasing depth of the perforation region.</p> |
