  • Patent number: 5930734
    Abstract: The invention relates to a method for measuring the thickness of non-circular elongated workpieces in which the thickness of the workpiece is measured along three measuring axis, the measurements are fed into a computer to determine minimum and maximum values and associated angular positions of the measuring axis, the measuring systems are rotated to a zero measuring position and the measured thicknesses are correlated by an algorithm, and the computer computes the degree for which angular position of the mimimum and maximum changes when the workpiece is advanced.
