The gripper drum includes at least one gripper to individually remove respective signatures and a stopping device. The stopping device including a stop element to stop and align the signatures with the fold of the signatures in a forward direction. The sheet feeder includes an opening device to open the individual signatures, to deposit the signatures on the conveying device, and to reverse the forward direction of the signatures. The sheet feeder includes a delay element moving in the same direction as the gripper drum and at a conveying speed less than the gripper drum speed. A press-on device to press the signatures released by the gripper against the delay element and to slow down the individual signatures prior to the signatures hitting the stop element.

Abstract: For attaching at least one flat supplementary product to a printed product, one leaf of the printed product is brought from a folded configuration into an essentially horizontal orientation. A supplementary product is attached, especially by an adhesive, to this horizontal leaf, preferably from above. Supplementary products can be attached to the front side and to the rear side of the printed product. The supplementary product is, for example, a commercial sample or a card.
