Manufacture of a two-sided product with an integrated device including microscale structures

摘要

Apparatus for producing a two-sided product with an integrated device on a material web, comprising: a first rotating microscale structure forming unit for providing a first structure for forming a first microscale structure on one side of a web section; a second rotating microscale structure forming unit having a second structure for forming a second microscale structure on a second side of the track section; wherein the first and second microscale structures and the track portion between the first and second microscale structures together form the integrated device; and a web feeding system for feeding the web of material between the first and second rotating microscale structure forming units.
