Machine geometry modification
Machine geometry changes are improving PM runnability and speed.
Already a small change can make a big difference on sheet run.
Unsupported section change:
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.
Supported section change:
Runnability problem in the group caps are solved by minimizing the open free draw. EVsf web stabilizer can be installed to the group cap.
