Keeping-Up with Extrusion

Extruder Line Converted To Four-Motor Drives—April 2007

Several extruder OEMs offer the four-motor, high-torque CMG drive from K&A Knoedler GmbH in Germany-but only on a single small extruder size, typically 90 mm. Addex Inc., Stoughton, Mass., is believed to be the fi rst machine builder anywhere to offer the four-motor drive on all its blown film extruders from 50 to 120 mm. Knoedler's drive uses a cluster of relatively inexpensive, conventional AC asynchronous motors. It reportedly offers high torque and 5% to 10% energy savings. Extruders with the new drives will be introduced at the K 2007 show in Dusseldorf in October. Tel: (781) 344-5800 . www.addexinc.com
