摘要 |
A process for the production of an embossing roller comprising silicon rubber for the continuous embossing of the surface of a thermoplastic film comprises use of a laser beam to form a positive of the structure to be replicated on the circumference of a secondary roller followed by casting of a silicon rubber negative which is removed and attached to the circumference of the embossing roller. <??>A process for the production of an embossing roller comprising silicon rubber for the continuous embossing of the surface of a thermoplastic film whereby the embossing of the surface comprises a negative pattern of the surface structure to be embossed, preferably of a grained structure and is characterized by production of a secondary roller that comprises, at least in the region of its circumference, a plastic or metal material having a smooth circumferential surface followed by directing of a laser beam onto the circumference which is moved relative to the surface and controlled in relation to the surface structure of a real or imaginary pattern sample such that a positive representation of the surface structure is produced on the circumferential surface of the secondary roller. A uniformly thick layer of silicon rubber is cast or applied to the circumferential surface and vulcanized to form a daughter embossing tool that is peeled from the secondary roller and adhered to the circumference of an embossing roller with the negatively structured embossing surface to the outside. |
