FIELD: woodworking industry.
SUBSTANCE: invention relates in particular to band saws for high-performance and high-quality division in the longitudinal and transverse directions of the wood of soft-wooded broadleaved species. A band saw for processing the wood of soft-wooded broadleaved species contains a body, alternating main teeth (2), made straight-sharpened, and scoring teeth (3), acting as smoothing tools and made bevel-sharpened. The height difference between the main and scoring teeth is 0.5 mm. Between the main and scoring teeth there are guide teeth (4), the height of which is equal to the height of the main teeth. The guide teeth protrude beyond the outer contour of the band saw by the amount of elastic recovery of wood fibres equal to 0.1-0.2 mm, and have a lateral radial undercut angle of 40 minutes.
EFFECT: quality of the cut walls increases without reducing the productivity of the sawing process.
