On June 1 and 2, less than three months after its startup, the PM 2 paper machine at Propapier PM2 GmbH in Eisenhüttenstadt, Germany, produced corrugating medium (Wellenstoff) at a basis weight of 80 and 90 g/m2at a speed of more than 1,500 m/min for several hours. The top speed reached during the test period was 1,602 m/min.
The speed test was started on June 1. The machine speed was continuously increased from 1,300 to 1,600 m/min. During the 19 hours from the moment it reached the speed of 1,500 m/min until the end of the test run at a speed of 1,602 m/min, the PM 2 line continued production without any breaks. The hourly production intermittently exceeded 90 tonnes, and the quality of the produced Wellenstoff was excellent, according to Metso.
