METHODS AND DEVICES FOR PROCESSING POLYMER FILMS |
摘要 |
Stretched polymeric films can be used in a variety of applications, includin g optical applications. The stretching conditions and shape of the stretching tracks (64) in a stretching apparatus can determine or influence film properties. Take-away systems (140, 140.prime., 141, 141.prime. ) can be use d to receive the film after stretching. The configuration of the take-away system can, in at least some instances, influence final film properties.</SD OAB>
