The apparatus for forming an imbricated product formation, in which the pitch between successive printed products can be deliberately selected, comprises successively arranged first and second conveyors. A scanning device detects the printed products arriving on the first conveyor at a first imbrication pitch, and delivers for each printed product a signal to a measuring unit. This measuring unit determines a time dependent value, such as the repetition frequency of the signals produced by the scanning device and delivers such to an evaluation circuit. In the evaluation circuit the thus determined time dependent value is combined with a signal proportional to the deliberately selected pitch between the products and which deliberately selected pitch is different from the first imbrication pitch, and the resultant signal value is delivered to a motor regulator. This motor regulator compares this resultant signal value with a signal generated by a tachogenerator coupled to a drive motor driving the second conveyor, and reglates the drive motor such that the conveying velocity of the second conveyor is adjusted such that the pitch or spacing between successive printed products corresponds to the deliberately selected pitch or spacing.
