ABSTRACT:
A saw machine with one or more saw blades for ripping a log, after which are provided one or more parting knives. The problem occurring in saw machines of prior art is that the spacing of the fixed guiding points working the log, as viewed in the direction in which the log is being sawn, becomes so large that curve-sawing is no longer possible. The saw machine of the invention is characterized in that both the saw blades (7) and the parting knives (8) are located in a separate sawing unit (6) articulatedly attached to the frame (9) of the saw machine and thereby following the crookedness of the log (11).
