Improved tail threading process at the Sappi Somerset mill (PM2) in Skowhegan, Maine
EV Group Oy (EVG) contributed to an improved tail threading process at the Sappi Somerset mill’s paper machine 2 (PM2) in Skowhegan, Maine. Bottlenecks in the PM2 tail threading process have been efficiently eliminated by installing a system for the transfer of the tail into the ropes in the single felted area of the machine. The delivery included the Gap, Stop, Cut and Transfer blow Technology, supported by a tail threading vacuum zone being drilled to one dryer cylinder on site. The rope pulleys were also relocated, adjusted to the new technology being installed. Additionally, the dryer section improvement supporting edge nozzles was installed in the press section to prevent harmful sheet edge flutter after the suction transfer roll.
The total delivery of the rebuild was supported by EVG Engineers, who supervised both the installation and start-up. After the PM2 improvements, tail threading into the ropes became more efficient and reduced the overall time needed for threading. The original project targets for threading were clearly achieved!
