Stretched polymeric films can be used in a variety of applications, including 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 used to receive the film after stretching. The configuration of the take-away system can, in at least some instances, influence final film properties.

Des films polymères étirés peuvent être utilisés dans une variété d'applications, y compris des applications optiques. Les conditions d'étirement et la forme des voies d'étirement (64) dans un appareil d'étirement peuvent déterminer ou influencer les propriétés des films. Des systèmes de tirage (140, 140', 141, 141' ) peuvent être utilisés afin de recevoir le film après étirement. La configuration du système de tirage peut, au moins dans certains cas, influencer les propriétés finales de films.
