Abstract
The invention relates to an intermediate product, a method for processing the intermediate product and a wood chipping device for processing the intermediate product. The intermediate product is substantially rod shaped and is sized in a range that includes between one and two times as oriented strand (OS) chips. The intermediate product is fed to a wood chipping device. The wood chipping device has a number of blades. The number of blades each have a number of cutting edges that run parallel to a blade ring axis, and which enclose a working chamber. The intermediate product is rotated about the blade ring axis and is aligned in such a way that it lies substantially parallel to the blade ring axis and is pressed by centrifugal force against the cutting edges.
