摘要： Method for producing an aluminum foil with integrated security features. An aluminum foil is rolled down to a thickness of less than 150 μm in a plurality of cold rolling passes, texturing that runs in the direction of rolling being induced simultaneously on both surface sides of the foil. In a final cold rolling pass, the foil is fed to a working roller pair, in which, on at least one roller surface, the relief-like surface structuring generated in the rolling direction by grinding was reduced on the basis of contrast and motif in a region of 10 to 50% relative to the average surface roughness to form a motif for a security feature that is transferred to the surface side of the foil facing the roller surface. The generated aluminum foil has a glossy appearance on both sides such that the security feature rises clearly due to its dull appearance.
摘要翻译： 具有集成安全特征的铝箔的制造方法。 在多个冷轧道中，铝箔被轧制成小于150μm的厚度，在箔的两个表面侧同时诱导在轧制方向上延伸的纹理。 在最后的冷轧道次中，将箔送入加工辊对，其中在至少一个辊表面上，通过研磨在轧制方向上产生的浮雕状表面结构减少，基于对比度和图案 相对于平均表面粗糙度为10至50％的区域，以形成转印到面向辊表面的箔的表面侧的安全特征的图案。 生成的铝箔在两侧具有光滑的外观，使得安全特征由于其暗淡的外观而明显上升。
