ABSTRACT:
A wood-chipping cutter drum is rotatable about a drum axis and carries at least one elongated blade which has a cutting edge defining an orbit of rotation of the drum and which is radially displaceable in a blade direction relative to the drum axis. An adjustment device for aligning the cutting edge on an ideal desired orbit centered on the drum axis has an elongated alignment bar with a flat surface that can be brought into engagement with the cutting edge of the blade on a non-rotating drum to push it into a position lying exactly on the desired orbit. This bar is pivotal about an axis parallel to the cutting edge being adjusted and positioned relative to this cutting edge so that a line between the point of contact with the bar and the pivot axis for the bar forms a right angle with the displacement direction of the blade in the drum.
