Paper machine equipment vibration problems can be very complicated to troubleshoot, because the source of the vibration is not always local, but may be generated from process equipment far upstream. ...Jake Zwart’s extensive practical engineering experience with vibration measurement and analysis makes his company “Spectrum Technologies” very effective in troubleshooting and resolving complex paper machine vibration issues to optimize the process.

Our stack has had a barring problem for as long as we can remember. Finally we asked Jake Zwart to recommend offsets for our stack. After installing the offsets as recommended, we have run our stack under a variety of operating conditions, changing both grade and speed. The stack has been running very smoothly without a trace of barring. We are very satisfied. When it comes time to change the next stack in this mill, I will be pushing to have Jake calculate the offsets.
