Rebuild in 1991: FLENDER Gearbox (ratio 2:1) at unwinder for rolldiameter increase and 50% speed reduction
With this rebuild the diameter of the PM-roll at the unwind was increased from appr. 2.15 m to 2.60 m. We added an additional gearbox (ratio 2:1) between the generator at the unwind and the PM-roll in order to be able to increase (double) the torque without replacing the generator and drive system. The motors of the drums were replaced.
