Abstract
In the method for manufacturing embossing rollers for a device for embossing packaging materials that comprises a set of at least two embossing rollers of which one is driven, and whereby the embossing roller set comprises a male roller having a male surface structure including structural elements and/or logo structures and a female roller having a female surface structure that is associated to the surface structure of the male roller for the common embossing operation with the male roller, the female surface structure is produced independently of a previously produced or physically pre-existing associated male surface structure. Along with a high embossing accuracy, this allows creating a very large variety of embossing structures, on one hand, and using a very large number of the most diverse materials, on the other hand, as well as reducing transverse tensions in the embossed material.
