ABSTRACT OF THE DISCLOSURE THICKNESS MEASUREMENT ON PRINTED PRODUCTS IN A SCALE FLOW In a scale flow, particularly in A dense scale flow (54) of flat articles, e.g. printed products, the thickness of each individual element between a deflectable measurement part and a reference part is measured, in that the reference part in a timed movement for each measurement engages below that part of the scale which forms the surface of the scale flow. In the preferred embodiment of the apparatus the reference part is constructed as an impeller (22), which is positioned laterally of the scale flow (54) in such a way that its vanes (22.1/2/3/4), if the impeller (22) is rotated about its spindle (23), are moved between the scale located on the surface and the remainder of the scale flow. The deflectable measurement part is constructed as a sensing roll (21), which is pressed into an adjustable neutral position by a spring tension. The deflection of the sensing roll (21) is measured and interrogated in timed manner. The timed cycle of the movement of the reference part and the timed cycle of the interrogation of the measured value are synchronized and are matched to the speed of the scale flow and the reciprocal spacing of the scale flow elements.
