ABSTRACT:
A method and apparatus for controlling a conveyance of printed products are provided according to which the printed products are conveyed continuously and in successive manner in a conveying direction into a region adjacent a circuit when the circuit is open. The circuit includes at least two conductor parts and a voltage source. The printed products are scanned by simultaneously bringing the two conductor parts into scanning contact with a metallic contact portion of either a printed product or of a support therefore where such support is provided. The circuit is thus closed for allowing electric current to flow in the circuit. An actual time behavior of the electric current flowing in the circuit is monitored and a control signal in response to a divergence of the actual time behavior of the electric current from a desired time behavior of the electric current is generated.
