Nicholson FiberGuard Feedrolls with replaceable inserts save high-value wood fiber and feedroll rebuild time! TOLL FREE: NORTH AMERICA PARTS 1-888-656-3131 New Nicholson A8 and A5B Highspeed Debarkers come standard with Fiberguard feedrolls.  Most older Nicholson roll feed debarkers from 12 to 44 inches, and many debarkers from other manufacturers can be retro-fitted with Fiberguard feedrolls. You can now quickly reconfigure your feedrolls to provide significantly more useable fiber for your products. Our simple bolt-on FiberGuard Inserts can be quickly changed to provide more or less aggressive feedroll gripping forces. Spikeless Nicholson FiberGuard Feedrolls (Patented) provide more contact area than spiked rolls to avoid penetration of the log’s surface and protect the high-value wood on the outside of the log. You can change inserts quickly to adjust to seasonal and log supply changes. FiberGuard is the way to adjust to frozen log applications. Well maintained feedrolls need far lower clamping pressures. This saves surface fiber, air, electrical power and your debarker! You will also reduce the time and cost of rebuilding your feedrolls. A FiberGuard Feedroll can be rebuilt in 2 hours or less, as compared to the typical 17 hours required to rebuild a standard feedroll using the remove, cut, weld and re-install method. You only need a wrench!. No welding, grinding, cutting or alignment jigs!  And using FiberGuard inserts will make sure that the top of every feedroll flute is at the same height. This avoids the major problem of having to increase roll pressure due to areas of no contact on flutes that are not at the correct height.  You can even rebuild the rolls one at a time on the debarker during regular maintenance. No need to remove the feedrolls from the debarker (a time and safety advantage). Fiber savings and important maintenance advantages make these rolls an economic necessity for your mill!  Call Nicholson today and get a quote for upgrading your debarker to FiberGuard Quick Change Feedrolls!
