The method is especially characterized in that at least one of the guides (9,11) of each blade (4), and in such a case guides corresponding to each other for all blades (4), separate or together with said corresponding guide of remaining blades in the form of a guide package (9?,11?) during the sawing are floating substantially in the axial direction of the blades (4) and hereby continuously positioned laterally in response to move- ments and position of the workpiece (1) being sawn, substantially in the axial direction of the blades in connection to the guide or guide package and/or the lateral movements and lateral position of the blade(s) in connection to the guide (9,11) or guide package (9?,11?).
