Abstract
A disc chipper having a knife disc having a plurality of segments, each segment separated from an adjacent by a chip opening extending segment approximately in the radial direction of the knife disc between the inner and outer peripheries of the knife disc. The disc chipper further has at least one knife for each segment, located in the segment in the vicinity of the chip opening preceding it in the rotational direction and extending a distance axially from said knife disc and supported between two opposing surfaces. The disc chipper further includes at least one wedge element for each segment, adapted to adjust the position of at least one of the opposing surfaces relative to the knife disc, for setting the axial reach of said knife to a desired value. Characteristically, the wedge element is situated in the segment essentially at the end adjacent to the preceding chip opening.
