DEVICE FOR BAND SAW BLADE TENSIONING Russian patent published in 2019 - IPC B27B13/08 

FIELD: woodworking industry.

SUBSTANCE: invention relates to woodworking industry, in particular, to tape saws tensioning devices. Device for band saw blade tension comprises power electromagnetic elements and sawing blade from magnetic material. Power electromagnetic elements are made in the form of linear motors installed in upper and lower parts of cutting zone. Linear motors envelope the saw blade with the stator in contact with the gap between the internal side surfaces of the motor stator and the saw blade. Linear motors provide electromagnetic forces which create multidirectional, balanced and balanced stretching forces of the working section along the longitudinal axis of the saw.

EFFECT: increased rigidity and stability of saw in cutting zone.
