Abstract: A band saw, a band saw assembly, and a method of spatially positioning a band saw blade are suggested. The band saw comprises a band saw blade against which a sawing material is adapted to be guided in a feed direction. A guide for the band saw blade has at least one magnet exerting a force on the band saw blade determining the spatial position thereof. The at least one magnet is adjustable in its force effect and the force is directed transversely to the feed direction. The guide, as viewed in the feed direction of the sawing material, has a front magnet and a rear magnet, the magnets facing a front area and a rear area, respectively, of the band saw blade. A method of spatially positioning a band saw blade is executed while a sawing material is guided against the band saw blade in a feed direction. A magnet force is exerted on the band saw blade. The magnet force, and thereby the position of the band saw blade is adjusted transversely to the feed direction.

Abstract: An apparatus for producing an essentially wedge-shaped wood flake comprises a chipping tool rotating about a first, horizontal axis for chipping the flake out of the wood such that the flake has a first, concave surface and a second, convex surface. 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.

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.
