The flake is delimited between the surfaces. A circular saw blade is provided rotating about a second, vertical axis for removing wood in an area in which the surfaces intersect in an imaginary tip, prior to the chipping out.

  • Patent number: 6532850
    Abstract: A method and an apparatus for dissecting logs in a sawing installation are disclosed. The installation having a reciprocally moving longitudinal conveyor for moving the logs reciprocally through a double band saw assembly utilizing band saw blades having sawing teeth both on a forward longitudinal edge and a rearward longitudinal edge thereof. As a consequence, the log is sawn both during the forward stroke and during the backward stroke of the reciprocally moving conveyor. Between subsequent strokes the band saw blades are displaced radially with respect to the conveying direction such that during each stroke the log first comes into contact with an outward band saw blade and then with an inward band saw blade, both relative to the log axis.
