Addex Inc., Stoughton, Mass., claims it now can produce nearly perfect blown film rolls with an oscillating die—an industry first. Addex combines standard air-ring or IBC-based gauge control with die oscillation limited to an angle based on the distance between two die ports (to distribute port lines over the roll). The system, called ARC (Addex Roll Control), could be especially valuable to stretch-film producers. ARC reportedly allows an oscillating die to produce rolls of film with quality comparable to rolls made with an oscillating hauloff. Up to now, oscillating dies often produced rolls with as much as 10% weight variation among rolls slit from the same core. Addex’s first ARC system produced 40% less thickness variation and negligible roll-weight variation. (781) 344-5800 • ww.addexinc.com
