ABSTRACT:
To prevent formation of burrs and splinters upon sawing a workpiece (3) with a continuously moving saw band (9) operating in a cutting movement direction (18), the saw band (9) is guided at an inclination or angle (19) with respect to a support surface (2) of the workpiece (3) at least just before cut-through, in which the angle (19) is open or away from the support surface, with respect to the cutting movement direction (18). A saw band holder (8) can be tipped or tilted about a pivot axis (7) offset from the support surface, or guided, already initially, at the angle which, preferably, is between about 1.degree. and 10.degree. and, especially, about 3.degree..
