Method for producing structured, particularly deep-structured folded material web, involves providing material web with regularly arranged structures, particularly with distorted and bent structures with foldings and cavities

摘要

The method involves providing a material web (1) with regularly arranged structures, particularly with distorted and bent structures with foldings (7, 8) and cavities (6). The recesses are formed transverse to V-shaped matrix increasingly deep and perpendicular to the plain. The convex sides of the recesses are pressed against the convex sides of the bent cavities of the material web. The ruffle of the structured edge is same as the ruffle in the structured material web. An independent claim is also included for a folded, structured material web with a base.
