Abstract
A method for detecting the local and overall distribution of tension in saw blades involves elastically deflecting a properly-tensioned model blade, which is loose in the center, into a compound curvature in the form of a saddle, and adjusting the amount of deflection until the blade surface becomes flat and rectilinear along one of two perpendicular axes of the deflection. Any similar blade of unknown tension which is to be treated is then subjected to the same deflection, and inspected for rectilinearity along the same axis of deflection. Any regions projecting from this axis contain excess tension, and are designated for hammering to loosen them. The blade is rotated while the deflection axes remain stationary, so that the local and overall tension levels in the entire blade may be conformed to those of the model blade.
