FibreMax feedrolls

Valon Kone debarkers come standard with new FibreMax feedrolls which feature replaceable inserts. The new feedrolls improve efficiency and reliability of the debarker, as well as minimise fibre loss. The FibreMax feedroll is a patented product.

Three different insert models

Three different insert models for varying debarking conditions are available for FibreMax feedrolls. The sharpened teeth is installed as standard in all VK machines. It is intended for debarking in normal conditions. A flat teeth can be used when the grip of the rolls is not as essential – for example, when debarking soaked wood. The third model, the spiked insert, is intended for debarking in difficult conditions, when the wood is frozen, for example. The various insert models can be used simultaneously on separate feedrolls of the machine. This can be done to minimise the marks left on the wood by the rolls.

Minimal wood loss and better chip quality

FibreMax feedrolls ensure that the wood is held in place and that it does not rotate in difficult debarking conditions. Therefore, the risk of splitting the ends of a log is reduced. The new feedrolls do not leave cutting marks on the logs, which improves the quality of the woodchips.

Easier maintenance of the feed rolls

The reliability of the FibreMax feedrolls is easy to maintain thanks to the simplicity of the maintenance procedures. The screw-fastened inserts can be replaced quickly and without any special expertise. Replacing the inserts of a single roll takes about an hour.


The new FibreMax feedrolls can be installed on the old VK debarkers as a retro-fit package. For more information about FibreMax feedrolls, please contact Valon Kone Sales or After Sales.
