How is bark removed from roundwood products?
Bark can be removed by hand or by two types of machines. Hand peeling with a draw knife removes the bark and very little wood from the raw material. This process produces a unique look for untreated architectural purposes.Machine peeling allows most of the sapwood (the treatable wood) to remain on the raw material, making it the most desirable for pressure treatment. A “doweler” machine produces a product that is exactly the same diameter from one end to the other. This process yields a visually uniform architectural product that can also be treated properly if the right species is used.A “peeler” machine essentially follows the taper of the raw material. Depending on the type of machine, the operator can determine the amount of material removed and some or most of the taper can be taken out.The variables in each manufacturer’s peeling process can create a unique “finger print” of sorts for its products.
