Process and apparatus for the measurement and correction of a stress profile in a saw blade

摘要

The continuous blade (10) is passed through the cutting station via alignment control monitors (28) and has the blade position monitored w.r.t. the guide plane. The blade is driven by friction rollers in a drive unit (26) alongside the cutting position, with the alignment control via the drive. The blade alignment is monitored at the edges of the blade. A support force at right angles to the blade plane is exerted at a position a set distance from the edges, and where the maximum amount of lateral distortion is expected. The cutting station and control system also regulates the tension in the blade.
