A circular saw blade straightening and tensioning machine has a set of straightening and tensioning rollers on both sides of a saw blade. The rollers are mounted on parallel shafts. Each shaft has a hub at its end, comprising a center portion horizontally eccentric with respect to the center line of the shaft, and a pair of side portions disposed on opposite sides of the center portion. Each of the side portions is horizontally eccentric with respect to the shaft center line, but in a direction opposite to that of the center portion. A roller is rotatably mounted on each of the center and side portions of the hubs. An actuator rotates each of the upper and lower shafts selectively ninety degrees in both the clockwise and counterclockwise directions. Rotation of the shafts selectively force a center roller against one surface of the saw blade while simultaneously forcing the side rollers against the other surface of the saw blade, thereby to level deformations in the blade. Rotation of the shafts in opposite directions forces the center rollers on both shafts against both surfaces of the saw blade, thereby to tension the blade. A sensor includes a movable foot pivotably mounted intermediate four fixed foot supports. The movable foot carries a gauge that measures the deviation underneath the movable foot from the plane determined by the fixed supports.
