FIELD: woodworking industry.
SUBSTANCE: invention relates to woodworking, particularly, to production of band-saws. Belt saw comprises web, toothed and trailing edges. Saw blade is divided into alternating sections of various rigidity connecting the saw and back edges of the saw and arranged with pitch corresponding to the teeth pitch. At the same time axis of section with lower rigidity coincides with top of base of tooth of saw tooth.
EFFECT: reduced bending rigidity of saw blade, reduced level of fatigue cyclic stress concentration in saw blade and higher reliability of tool.
