Definitions

  • Figure 1 is a side view of a conventional disc chipper.
  • Figure 2 shows the wood chipping process.
  • Figure 3 shows a knife disc seen along the shaft, from the knife cutting side or from the log feeding side,
  • Figures 4a and 4b show an application of the knife and guide component in a knife system according to the invention, from the knife side and as a cross-section.
  • Figure 4b shows an asymmetrical guide 14 which is turned around to obtain two different distances from the cutting edge of the knife 10.
  • Distance L + T is with an unsharpened knife and distance L with a sharpened knife, whereby T is the sharp ⁇ ening distance.
  • Figure 5 shows another structural application of a knife 9' , whereby the cutting edges 30 and 30* of a section knife 10' are on the same side of the knife, that is, they meet the plate surface 12.
  • the knife 10' according to Figure 5 has a recess part 12' made in the plate surface and providing surfaces 12 and 12' with a level difference k. Given the structure shown in the figure, the surface 12 work ⁇ ing chips loose from the log is at a higher level than the mounting surface 12• and thus the risk of penetration by dust and sticks is considerably less than with one level surface
  • the knives in a chipper according to Figure 9 are exchange ⁇ able from one side of the disc by means of screws 31 extending through the knife holder component 23.
  • the system according to Figure 9 also guarantees that sticks resulting from the chipping will not enter between the knife block 21 and the knife 10, because the knife surface 12 protrudes from the joint between the knife block 21 and the knife towards a chip opening 41, thus protecting the joint from the chip flow.
