ABSTRACT:
For counting printed products (D) conveyed in a scale flow, a contact element (K) is moved in the printed product conveying direction at a speed (v.sub.2) higher than the conveying speed (v.sub.1). Thus, the contact element (K) contacts the trailing edge (F.sub.k) of a printed product (D.sub.k) and on each contact a counting pulse is emitted and the contact element is subsequently returned to its starting position. This process is cyclically repeated correlated with the average time interval between two succeeding printed products (D.sub.k, D.sub.k-l).
