Machine geometry modification

Machine geometry changes are improving PM runnability and speed.

Already a small change can make a big difference on sheet run.

Runnability problems at the section change can be a bottleneck also after the single felt has been equipped with web stabilizers. These problems are a result of moving surfaces, and mainly caused by pressure differences and axial air flows caused by pumping effect of dryer fabrics.

Runnability problem in the group caps are solved by minimizing the open free draw. EVsf web stabilizer can be installed to the group cap.
