RPM CalculatorGetaGrip! Ending Roll RPM Calculator

The rolls must move the lumber from one side of the production line to the other, during the time it takes for the production line to move the lumber the length of the rolls.

This difficult calculation is made easy with our exclusive Ending Roll RPM Calculator featured below.

  • Finding just the right ratio of lugs per minute to ending roll RPM involves 5 variables.  It is critical for optimizing all ending roll systems and transfer roll cases.

  • Optimum velocity for the lumber is fast enough to hit the target and slow enough to minimize bounce back.

  • Maximum traction with GetaGrip! holds the lumber in position.

  • For ending rolls, the ratio of lugs/min to roll RPM stays the same when the lugs/min changes.  Mill designs need to tie the 2 together.  If the lumber line stops, slows or speeds up, so do the rolls.

Replace the blue numbers with your own.  To calculate, click on the Total or press your 'Tab' key.   Want us to figure it out?  Call toll free in USA & Canada 1-888-339-4747
