Surveys & Alignments

Precision alignment of paper production equipment as well as other large rotating equipment is a critical factor in their maintenance.  Alignment using optical or laser methodology depending on the specific requirements extends the life of machinery and markedly improves product quality. Alignment often allows for increased machine speeds, as well as reduced waste and downtime.

The PPD Group Engineers are experienced in aligning machinery in all areas of industry. We can align paper, printing, hydro, or any other process line that needs alignment.

Typical problems include:

  • Tracking problems
  • Slow machine speeds
  • Short felt life
  • Erratic seams
  • Coating profile
  • Baggy edges
  • Wrinkles
  • Bearing wear
  • Poor product quality
  • Vibration
  • Misalignment in drive systems
  • Scissor effect between press rolls
  • Head box profiles
  • Uneven dewatering
  • Wet end and foil misalignment
  • Roll misalignment
  • Bent or warped machine frames
  • Misalignment due to poor installation
  • Misalignment due to settling
  • Lin shaft bearing misalignment

To date, the PPD Group has performed hundreds of Alignment surveys and corrections both Nationally and Internationally. We have also been involved in many major Installations throughout World.

Alignment Recording 

All alignment readings are recorded and issued with the equipment drawing in AutoCAD format.
