My TAPPI Story: McKenna Goulette
It was in the late ‘60s that Mead Paper decided to add the No. 3 Paper Machine and Off Machine Coater (OMC) to its mill in Escanaba. Beloit Corporation designed and built the machines using a lineshaft with a differential mechanical drive system with analog DC helper drives. The Paper Machine’s lineshaft is driven with a classic steam turbine. The Off Machine Coater’s lineshaft prime mover is two “in-line” dc motors and respective drives.
The Drive Systems have been up-graded several times over the years, but this paper is about the February 2002, OMC mechanical rebuild that replaced the PIV’s on each of the machines five lineshaft differentials.
