Forest Products Industry

The forest products industry is overgrown with issues for which mills have little control. Changing tax laws and legislation, tariffs, supply and demand all affect your business’s bottom line. Regain control of changing costs by taking charge of production processes in your lumber, flooring or roofing product mills – beginning with your rolls!


When your Sander Tension Rolls, Sander Guide Rolls and Sander Pressure Rolls are round, free of chatter, and working at - or better than - OEM specifications, your mill will experience consistent and accurate results in many ways:

  • Improved product quality
  • Very uniform product thickness due free of sander roll defects
  • Improved process efficiency
  • Reduced downtime due to unplanned maintenance and catastrophic equipment failure
  • Reduced waste and energy consumption


Four Keys to Roll Optimization

If your rolls are out of specification, you’re bound to have performance problems. Your equipment will not run as fast and will, in time, cause inconsistencies throughout your product. PRG’s service incudes adjustments to all four critical aspects of roll optimization:

  • Balance –PRG’s Dynamic Balancing Machine enables the precise simulation of your plant’s operating conditions, allowing for perfect synchronization between rolls, rotors and drums.
  • Tolerance – Plywood, veneer and other products require precision with no variation in thickness. Tight tolerances are the key to greater uniformity across your product line.
  • Roll Profile – Roundness prevents the most common roll defects – namely barring, feedlines and chatter. Even slight roll inconsistencies produce defects at high speeds.
  • Bearing Life Improvement – Regular inspection of both bearings and bearing seats will ensure concentricity to the roll face.


PRG guarantees your rolls will be in spec. If It’s Not in Spec, Don’t Send us a Check! PRG’s maintenance includes:

  • Ensuring rolls are round and concentric with profiles in specification in all 360 degrees around the roll
  • Removal of roll defects
  • Complete inspection of housing and bearings
  • Correction of bearing and journal fit so that rolls run to full bearing life
  • Detailed cleaning and painting of housing
  • Match set requirements for the diameter of drive roll pairs
