'THE MACHINES ALWAYS HAVE TO IMPROVE'

摘要

Smurfit Kappa Hoya in Germany has an interesting history, the site was originally a military airport, and then was transformed into a carton miU in 1957. And the word "transformation" is a key word at Hoya, as it keeps pace with ever more demands on speed and output. The mill uses 100% recycled fiber as its raw material source and has two machines PM 2 and PM 4, but it is PM 2 that has seen a flurry of attention over the years. The machine's original specification when it was started up in 1990 was of a 7.5 m wide linerboard machine producing 150,000 tonnes/yr of 100-300 g/m~2 product at a speed of 600 m/min. It was rebuilt in 2001 which increased the speed up to 710 m/min and increased output to 290,000 tonnes/ yr of fluting and testliner. But more recently, even more was needed out of the workhorse PM 2.
