    摘要: Disclosed herein are embossing drums, systems, methods for their use and their maintenance, and films made using the drums. In one embodiment, an embossing drum system can comprise: a mandrel, a primary journal extending from a first end of the mandrel, a secondary journal extending from a second end of the journal, and a seamless sleeve disposed around the mandrel to form a drum. The sleeve comprises a pattern cut into a sleeve outer surface. In one embodiment, a method of making optical films, comprises: introducing a polymer to an embossing drum system, forming the pattern into a surface of the polymer to produce a film, and removing the film from the drum. The embossing drum system comprises a drum with a pattern cut into a drum outer surface. The film has a continuous, seamless pattern having a length that is greater than the drum circumference.
