Weig Karton Saves 190 Hours/Yr for Roll Cleaning at Mayen Plant in Germany

Due to severe fouling inside the DuoStabilizer rolls of the first dryer group on its KM 6 board machine, Weig Karton, Mayen, Germany, has had to clean the stabilizer rolls once a year. This cleaning process is extremely laborious, as the approximate 130 mm thick tender side covers have to be dismantled every time. As production time increased, the dirt on the rolls caused considerable difficulties.
The mill worked with Voith, Germany, and its FRS OnSite group to make the laborious cleaning process easier. The project began with drilling manholes into the tender side covers of five rolls. In addition, openings and covers were provided in the disks separating threading zone and rolls. These measures allow Weig Karton to save about 38 hours of cleaning work a year for each of the five rolls – around 190 hours in total.
The difficult part of this process was to drill through the particularly thick covers. But after just 80 man-hours, FRS OnSite successfully completed its work on KM 6, considerably faster than envisaged in the ambitious 96-hour scheduled program. It was also possible to dynamically balance the DuoStabilizer rolls during this mechanical service at the customer's premises. This helps the machine run at optimum performance.
At its Mayen plant, Weig produces board on two machines, KM 3 and KM 6. The 5.30 m wide KM 6 machine produces about 340,000 metric tpy of plasterboard for the corrugated and plasterboard industry.
