Abstract
To determine the thickness profile of rolled metal sheets by measuring the absorption of X-rays a slit diaphragm is used which is rotatable about the imaginary center axis of the X-ray tube, the rotation consisting of a reciprocating movement lying in a range of less than 36.degree.. Between the reversal points of the rotation the rotational movement takes place in steps with rest intervals lying therebetween.
