Abstract
A system for introducing 'tensioning' stress distribution into the wide bandsaw blade without its plastic deformation, for automatically compensating for blade temperature expansions and blade manufacturing inaccuracies, and for controlling blade position on the bandsaw wheels, comprising: torsional loading of the back, noncutting section of the bandsaw blade by using two actuators acting as a couple; continuously sensing for a displacement of the bandsaw blade during sawing from a set position on the wheels and countering the adverse effect of such displacement by generating a corrective displacement in the opposite sense relative to the said set position through the change of the ratio of forces forming the said couple.
