A system has: a transport chain, which is roof-shaped in an upper region, along which printed products are transportable astride, collectable, and optionally stitchable in an intermediate stitching station; and a stop, which is adjustable in accordance with a format of a printed product of the printed products being delivered, is arranged in a transport direction of the printed products, and is positioned after the intermediate stitching station along the transport chain, the stop corresponding to a location of delivery of the printed product from the transport chain. A cyclic transfer of the printed product during the delivery takes place via a delivery system, the delivery system having in an infeed region a printed product transporter configured to transfer the printed product being delivered, the printed product transporter having pivot arms, the pivot arms being controllable according to a measured thickness of the printed product being delivered.

A saddle stitcher for printed products includes a saddle chain; a stitching machine; a controller; an ejector; and a delivery system. The delivery system includes: at least one lower conveyor belt and one upper conveyor belt; and at least one deflection roller for the lower conveyor belt, the at least one deflection roller being arranged in a radius. The lower conveyor belt has a first controllable self-propelled drive. The upper conveyor belt has a second controllable self-propelled drive. The controller is configured to separately control the first controllable self-propelled drive and the second controllable self-propelled drive. The controller is configured to provide a control that is exact to a cycle and is adjustable according to a thickness and a format of a respective printed product in a product flow.
