During the downtime, Metsä Tissue noticed some problems with the sealing of the Yankee cylinder. Voith tissue engineers worked through the day and night to seal the Yankee and to re-start production as soon as possible on PM2 at Metsä Tissue’s Stotzheim mill.Voith Paper and Metsä Tissue worked out an operation schedule to not only be able to seal the Yankee, but also to service the suction press roll in the Voith Service Center at the same time. The suction press roll was returned to the mill completely overhauled just two days later.Re-installation of the serviced roll and the successful work on the Yankee allowed PM2 to re-start production after only four days of downtime.
