The device has successively disposed receiving elements (14). These are formed by a channel-like base (42) and a wall (44) trailing as viewed in circumferential direction (U). The circumferential path (24) extends in the working section (38) at an incline such that the printed products (18) fed by means of the first conveyor (10) come to rest in the system at the base (42) and plane against the wall (44). A sliding body (60) is associated with each receiving element (14), the sliding body displacing the fed printed products (18) along the wall (44) of the receiving section (46) in the insertion section (48) by abutting the same. The printed products (18) are opened, wherein the second product part (18″) is placed behind the hold-open element (50), which is disposed on the forward receiving element (14). Inserts (20) are added to the printed products (18) by means of a second conveyor (12).
