ABSTRACT:
A thickness responsive blank gauge is disclosed for comparing the thickness and length of a flat blank to a standard blank. The gauge includes a thickness sensor positioned by the blank and an output indicator engaged by the thickness sensor. Operably associated with the output indicator is a device for shifting the output indicator a distance equal to the change in length from the standard times the reciprocal of a predetermined constant. The output indicator will shift a distance equal to the distance through which the thickness sensor moves if the ratio of the change in length of the blank from the predetermined standard to the change in thickness of the blank from the predetermined standard is equal to the predetermined constant.
