ABSTRACT:
In the checking of cigarettes, there is the problem that, for contactless measurement, they have had to be guided at an exactly defined distance from the sensor. It is proposed to measure the distance from the two axial end faces, to form the sum of the distances or standardize the signals relative to one another, and to generate an error signal resulting in separation out when the sum of the distances is outside a predetermined threshold range set in accordance with the color of the tobacco in the cigarettes.
