The apparatus for forming an imbricated product formation, in which the pitch or spacing between successive printed products is essentially constant, comprises two successively arranged conveyors. A scanning device detects the arriving printed products and delivers for each printed product a signal to a measuring unit. This measuring unit determines the repetition frequency of the signals produced by the scanning device and delivers such to an evaluation circuit. In the evaluation circuit the determined repetition frequency is multiplied by a signal proportional to a predeterminate pitch or spacing between the products and the resultant multiplication product is delivered to a motor regulator. This motor regulator compares this resultant multiplication product with a signal delivered by a tachogenerator and regulates a drive motor such that the conveying velocity of the second or downstream conveyor of the two successively arranged conveyors is adjusted such that the pitch or spacing between successive printed products corresponds to the predeterminate pitch or spacing.
