METHOD OF TENSIONING SAW BLADE AND CONTROLLING IT IN SAW MACHINE, AS WELL AS CONTROLLING AND TENSIONING DEVICE Russian patent published in 2011 - IPC B27B13/10 

FIELD: process engineering.

SUBSTANCE: proposed device comprises elements generating magnetic force and control elements to continuously regulate magnetic forces in sawing. Saw blade tension is controlled in sawing by elements generating magnetic force acting on saw blade. Saw blade moves sideway toward selected sawing line. Note here that sawing line is set in sawing part between aforesaid elements. Saw blade is continuously subjected to magnetic force effects in sawing. Saw blade from magnetic material is controlled by several pairs of elements generating magnetic force or driving sideway. Said pairs are located nearby saw blade relative blank to be sawn on its opposite sides. In the case of circular saw, said pairs are arranged at 180°. In the case of saw blade, they are arranged on parts of saw blade in different directions. Note here that magnetic forces and lateral driving forces are inter-adjusted. Simultaneous adjustment is used for the other element of the pair.

EFFECT: continuous action of elements generating magnetic force, ruling out of drive mechanical effects.
