Abstract: Apparatus and method for measuring the thicknesses of material on opposite sides of the reinforcing cord disposed within a tire ply, the material of the reinforcing cords having a high effective atomic number relative to the atomic number of the material applied to the opposite sides of the cords. Sources of X-ray radiation on opposite sides of the tire ply are directed at the tire ply. Radiation detectors on opposite sides of the ply having optimum sensitivity to backscatter radiations, produce first and second signal outputs, each of which have components functionally related to the thicknesses of the material on both sides of the reinforcing cords. Processing circuits are provided which process the first and second signals so that the first and second signals each are related to the thicknesses of material on both sides of the ply. Solution networks combine the processed signals to obtain third and fourth signals, the third signal being representative of the thickness of material on one side of the cord and substantially independent of changes in the thickness of rubber on the opposite side of the cords, and the fourth signal being representative of the thickness of material on the opposite side of the reinforcing cord and substantially independent of changes in the thickness of rubber on the other side of the cords. Optional apparatus for summing, subtracting and taking the ratio of the third and fourth signals to indicate the combined thickness of material on both sides of the cord, the difference of the thickness of material on one side of the ply compared to the other, or balance, and the cord position within the ply are provided.
