ABSTRACT:
A method for transforming a scale flow of printed products into a delivery flow of printed products in forced formation, typically a delivery flow in which each printed product is guided by a gripper, essentially comprises four method steps, namely a first deflection or reversal (1) through which a scale flow (B) with downwardly directed leading printed product edges is formed; a timing step (2) in which the spacings between the printed products are made uniform, increased; decreased and/or differentiated, a second deflection or reversal (3) in which a scale flow (D) with upwardly directed leading edges is produced; and an acceptance (4) in which the printed products are individually or groupwise taken over by grippers. The first and/or second deflection or reversal can be omitted. The apparatus for performing the method essentially comprises a supply belt conveyor (5) and a conveying away means (6), between which are arranged a timing element (21) and at least one intermediate belt conveyor. The timing element (21) has a stationary stop element (21.1), which individually or groupwise stops the printed products, and a movable conveyor element (21.2), which raises the printed products in timed individual or groupwise manner over the stop element (21.1).
