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.

Abstract: A variable-position die set for trimming metal or other sheet stock to a particular length which is determined by the stock thickness, including upper and lower actuating die plates, a stationary cutting block arrangement positioned between and secured to the die plates, and a movable cutting block arrangement positioned between the die plates in spaced parallel relationship with the stationary cutting block arrangement. Stock thickness-sensing apparatus is also positioned between the lower and upper actuating die plates. Operatively associated with the sensing apparatus is a device for positioning the movable cutting block arrangement in relation to the sensed stock thickness.
