ROLL TENSION MONITOR FOR SAW BLADE

摘要

Device for indicating roll tension or residual stress distribution in saw blade. Device has forming means for deforming selected length of saw into longitudinal curve of known geometry so that saw is bowed transversely across width thereof. Forming means has face datum and edge datum and selected length is located relative thereto. Sensing means adjacent saw face detects spacing of saw face from data. Visual display means cooperating with sensing means provides visual display of saw profile so that residual stress distribution can be assessed.
